+# GPU Passthrough Testing Guide with Safety Timeout
+
+This guide will help you safely test GPU passthrough with automatic revert functionality.
+
+## System Configuration
+
+- **CPU:** Intel i7-14700KF (NO integrated graphics)
+- **GPU:** NVIDIA RTX 4090 (01:00.0)
+- **Audio:** NVIDIA Audio (01:00.1)
+- **Display Manager:** SDDM
+- **Local IP:** 10.10.10.9
+
+## Safety Features
+
+All scripts include:
+1. ✅ **Automatic timeout** - VM shuts down after specified minutes
+2. ✅ **Error handling** - Attempts to restore GPU if binding fails
+3. ✅ **Comprehensive logging** - All actions logged to journald
+4. ✅ **Cleanup traps** - Ensures restoration on script errors
+
+## Testing Phases
+
+### Phase 1: Pre-Flight Checks (5 minutes)
+
+Run the system verification script:
+
+```bash
+cd ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH
+./gpu-passthrough-preflight-check.sh
+```
+
+**Expected output:**
+- ✅ IOMMU enabled
+- ✅ GPU and Audio devices found
+- ✅ SSH running
+- ✅ virt-manager installed
+
+**If any errors:** Fix them before proceeding.
+
+---
+
+### Phase 2: Test GPU Bind/Unbind (2 minutes)
+
+This test verifies the GPU can be bound to vfio-pci and restored WITHOUT starting a VM.
+
+**IMPORTANT:** Your display will go BLACK for 30 seconds during this test!
+
+**Setup:**
+1. Have SSH ready on phone/laptop: `ssh coops@10.10.10.9`
+2. Save all work and close applications using GPU
+3. Run the test:
+
+```bash
+cd ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH
+sudo ./test-gpu-bind-unbind.sh 30 # 30 seconds test
+```
+
+**What happens:**
+1. Display goes BLACK (SDDM stops, nvidia unloads)
+2. GPU binds to vfio-pci
+3. Waits 30 seconds
+4. GPU returns to nvidia
+5. Display returns (SDDM starts)
+
+**Via SSH, monitor the test:**
+```bash
+# Watch logs in real-time
+sudo journalctl -f | grep -E "gpu|nvidia|vfio"
+
+# Check current GPU driver
+watch -n 1 'lspci -k -s 01:00.0 | grep "Kernel driver"'
+```
+
+**Success criteria:**
+- ✅ Display goes black, then returns after 30 seconds
+- ✅ No error messages in logs
+- ✅ Desktop fully functional after restoration
+
+**If it fails:**
+- Display doesn't return: Via SSH, run `sudo systemctl start sddm`
+- Check logs: `sudo journalctl -t vm-gpu-start -t vm-gpu-stop -n 100`
+
+---
+
+### Phase 3: Install Hooks (1 minute)
+
+Install the libvirt hooks for automatic GPU passthrough:
+
+```bash
+cd ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH
+sudo ./install-gpu-passthrough-hooks.sh win11
+sudo systemctl restart libvirtd
+```
+
+**Verify installation:**
+```bash
+ls -la /etc/libvirt/hooks/
+ls -la /etc/libvirt/hooks/qemu.d/win11/
+```
+
+Should show:
+```
+/etc/libvirt/hooks/qemu (executable)
+/etc/libvirt/hooks/qemu.d/win11/prepare/begin/start.sh (executable)
+/etc/libvirt/hooks/qemu.d/win11/release/end/stop.sh (executable)
+```
+
+---
+
+### Phase 4: Create Windows VM (30-45 minutes)
+
+Follow the documentation in:
+```
+/home/coops/git/dusky/Documents/pensive/linux/Important Notes/KVM/Windows/
+```
+
+**Key steps:**
+1. Launch virt-manager
+2. Create new VM with Windows 11 ISO
+3. Configure: Q35 chipset, UEFI firmware, TPM 2.0
+4. Set CPU to host-passthrough
+5. Use VirtIO for storage and network
+6. Attach virtio-win ISO
+7. Install Windows
+
+**DO NOT add GPU to VM XML yet!** First verify Windows boots without GPU passthrough.
+
+---
+
+### Phase 5: Add GPU to VM (5 minutes)
+
+Once Windows is installed and working with QXL display:
+
+```bash
+# Edit VM configuration
+sudo virsh edit win11
+```
+
+Add inside `` section (BEFORE the closing `` tag):
+
+```xml
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+Save and exit (`:wq` in vi).
+
+**Verify XML:**
+```bash
+sudo virsh dumpxml win11 | grep -A5 hostdev
+```
+
+---
+
+### Phase 6: First GPU Passthrough Test (10 minutes)
+
+**CRITICAL SETUP:**
+
+1. **Open SSH session from another device:**
+ ```bash
+ ssh coops@10.10.10.9
+ ```
+
+2. **Set safety timeout (5 minutes for first test):**
+ ```bash
+ export GPU_PASSTHROUGH_TIMEOUT=5
+ echo "export GPU_PASSTHROUGH_TIMEOUT=5" >> ~/.bashrc
+ ```
+
+3. **Verify timeout is set:**
+ ```bash
+ echo $GPU_PASSTHROUGH_TIMEOUT # Should show: 5
+ ```
+
+4. **Start monitoring logs (in SSH session):**
+ ```bash
+ sudo journalctl -f -t vm-gpu-start -t vm-gpu-stop -t vm-gpu-timeout
+ ```
+
+5. **From host desktop, start the VM:**
+ ```bash
+ virsh start win11
+ # OR use virt-manager GUI
+ ```
+
+**What happens:**
+
+```
+Time Event
+---- -----
+0:00 Click "Start" in virt-manager
+0:02 Display goes BLACK (host loses graphics)
+0:05 Hook script completes
+0:10 Windows should appear on physical monitor
+0:15 Use Windows normally
+5:00 VM automatically shuts down (safety timeout)
+5:05 Display returns to Linux desktop
+```
+
+**Via SSH, monitor status:**
+```bash
+# Check if VM is running
+watch -n 2 'virsh list --all'
+
+# Check GPU driver
+watch -n 2 'lspci -k -s 01:00.0 | grep "Kernel driver"'
+
+# Should show: vfio-pci when VM is running
+# nvidia when VM is stopped
+```
+
+**Success criteria:**
+- ✅ Linux display goes black within 5 seconds
+- ✅ Physical monitor shows Windows boot within 60 seconds
+- ✅ Windows is usable with GPU
+- ✅ After 5 minutes, VM shuts down automatically
+- ✅ Linux desktop returns within 10 seconds
+
+**If something goes wrong:**
+
+Via SSH:
+```bash
+# Force stop VM
+sudo virsh destroy win11
+
+# Run recovery
+gpu-recovery
+
+# Or manually restore
+sudo /etc/libvirt/hooks/qemu.d/win11/release/end/stop.sh
+
+# Check logs for errors
+sudo journalctl -t vm-gpu-start -t vm-gpu-stop -n 100
+```
+
+---
+
+## Phase 7: Extended Testing (Optional)
+
+Once the 5-minute test works perfectly, try longer durations:
+
+```bash
+# 15 minute test
+export GPU_PASSTHROUGH_TIMEOUT=15
+virsh start win11
+
+# 30 minute test
+export GPU_PASSTHROUGH_TIMEOUT=30
+virsh start win11
+
+# Disable timeout (use manually)
+export GPU_PASSTHROUGH_TIMEOUT=0
+virsh start win11
+# You must manually shut down Windows or run: virsh shutdown win11
+```
+
+---
+
+## Troubleshooting
+
+### Display never returns after VM shuts down
+
+**Via SSH:**
+```bash
+# Check if VM is actually stopped
+virsh list --all
+
+# Check GPU driver
+lspci -k -s 01:00.0 | grep "Kernel driver"
+
+# If still vfio-pci, manually run stop script
+sudo /etc/libvirt/hooks/qemu.d/win11/release/end/stop.sh
+
+# Force restart display manager
+sudo systemctl restart sddm
+```
+
+### VM doesn't show on monitor
+
+**Possible causes:**
+1. Windows hasn't installed NVIDIA drivers yet (first boot)
+2. Monitor input not switched correctly
+3. GPU ROM issue (rare)
+
+**Check via SSH:**
+```bash
+# Verify GPU is in VM
+sudo virsh dumpxml win11 | grep -A5 hostdev
+
+# Check VM is actually running
+virsh list --all
+
+# Check GPU driver
+lspci -k -s 01:00.0 # Should show: vfio-pci
+```
+
+### nvidia module won't unload
+
+**Via SSH:**
+```bash
+# Check what's using nvidia
+sudo lsof /dev/nvidia*
+
+# Common culprits:
+# - Docker containers with nvidia runtime
+# - Wayland compositor
+# - Steam, Discord with hardware acceleration
+
+# Stop those services first, then retry
+```
+
+### VM crashes or freezes
+
+**Via SSH:**
+```bash
+# Check VM logs
+sudo tail -f /var/log/libvirt/qemu/win11.log
+
+# Force destroy VM
+sudo virsh destroy win11
+
+# GPU should auto-restore via stop hook
+# If not, manually run:
+gpu-recovery
+```
+
+---
+
+## Log Locations
+
+```bash
+# Hook execution logs
+sudo journalctl -t vm-gpu-start
+sudo journalctl -t vm-gpu-stop
+sudo journalctl -t vm-gpu-timeout
+
+# Libvirt logs
+sudo journalctl -u libvirtd
+
+# VM console output
+sudo tail -f /var/log/libvirt/qemu/win11.log
+
+# All GPU-related logs from last boot
+sudo journalctl -b -t vm-gpu-start -t vm-gpu-stop -t vm-gpu-timeout
+```
+
+---
+
+## Quick Reference Commands
+
+```bash
+# Start VM with timeout
+export GPU_PASSTHROUGH_TIMEOUT=5
+virsh start win11
+
+# Stop VM manually
+virsh shutdown win11 # Graceful shutdown
+virsh destroy win11 # Force stop
+
+# Check VM status
+virsh list --all
+
+# Check GPU driver
+lspci -k -s 01:00.0 | grep "Kernel driver"
+
+# Emergency recovery
+gpu-recovery
+
+# Watch logs
+sudo journalctl -f -t vm-gpu-start -t vm-gpu-stop
+
+# Test bind/unbind without VM
+sudo ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH/test-gpu-bind-unbind.sh 30
+```
+
+---
+
+## Safety Checklist
+
+Before EVERY test:
+- [ ] SSH accessible from another device
+- [ ] Know your IP address (10.10.10.9)
+- [ ] Timeout is set (`echo $GPU_PASSTHROUGH_TIMEOUT`)
+- [ ] All work saved
+- [ ] No other applications using GPU
+- [ ] Have phone/laptop ready for SSH
+
+---
+
+## Next Steps After Successful Testing
+
+1. **Install NVIDIA drivers in Windows VM**
+2. **Test gaming/applications**
+3. **Adjust timeout or disable it**
+4. **Consider network streaming (Sunshine/Moonlight) if you want to view VM from other devices**
+5. **Set up shared folders between host and VM**
+
+---
+
+## Removing GPU Passthrough
+
+If you want to go back to standard VM without GPU:
+
+```bash
+# Edit VM
+sudo virsh edit win11
+
+# Remove the blocks for GPU and Audio
+# Save and exit
+
+# Delete hooks (optional)
+sudo rm -rf /etc/libvirt/hooks/qemu.d/win11
+sudo systemctl restart libvirtd
+```
+
+The GPU will stay with the host (nvidia driver) all the time.

+
+## What You Need to Do Next
+
+### Step 1: Test GPU Bind/Unbind (5 minutes)
+
+This tests the GPU can be bound to vfio-pci WITHOUT starting a VM:
+
+```bash
+# Have SSH ready on phone/laptop first!
+# ssh coops@10.10.10.9
+
+cd ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH
+sudo ./test-gpu-bind-unbind.sh 30
+```
+
+**What happens:**
+- Your display will go BLACK for 30 seconds
+- GPU binds to vfio-pci, then back to nvidia
+- Display returns automatically
+
+**Success = Ready to proceed. Failure = Check logs and troubleshoot.**
+
+---
+
+### Step 2: Install Hook Scripts (2 minutes)
+
+```bash
+cd ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH/Single_GPU_KVM_PASSTHROUGH
+sudo ./install-gpu-passthrough-hooks.sh win11
+sudo systemctl restart libvirtd
+```
+
+Verify:
+```bash
+ls -la /etc/libvirt/hooks/
+ls -la /etc/libvirt/hooks/qemu.d/win11/
+```
+
+---
+
+### Step 3: Create Windows VM (30-45 minutes)
+
+Follow the documented procedure in:
+```
+~/Documents/pensive/linux/Important Notes/KVM/Windows/
++ MOC Windows Installation Through Virt Manager.md
+```
+
+**Key configuration:**
+- Name: win11 (must match hook directory name!)
+- Chipset: Q35
+- Firmware: UEFI with Secure Boot
+- CPU: host-passthrough
+- Storage: VirtIO (with virtio-win ISO)
+- Network: VirtIO
+- TPM: 2.0 emulated
+- Hyper-V enlightenments enabled
+
+**Important:** Test the VM works BEFORE adding GPU passthrough!
+
+---
+
+### Step 4: Add GPU to VM XML (5 minutes)
+
+Once Windows is installed and working:
+
+```bash
+sudo virsh edit win11
+```
+
+Add inside ``:
+
+```xml
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+---
+
+### Step 5: First GPU Passthrough Test (10 minutes)
+
+**CRITICAL PREPARATION:**
+
+1. **Open SSH on phone/laptop:**
+ ```bash
+ ssh coops@10.10.10.9
+ ```
+
+2. **Set safety timeout:**
+ ```bash
+ export GPU_PASSTHROUGH_TIMEOUT=5 # 5 minutes
+ echo 'export GPU_PASSTHROUGH_TIMEOUT=5' >> ~/.bashrc
+ ```
+
+3. **Validate readiness:**
+ ```bash
+ ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH/validate-gpu-passthrough-ready.sh win11
+ ```
+
+4. **Start monitoring (in SSH session):**
+ ```bash
+ sudo journalctl -f -t vm-gpu-start -t vm-gpu-stop -t vm-gpu-timeout
+ ```
+
+5. **Start the VM:**
+ ```bash
+ virsh start win11
+ ```
+
+**What will happen:**
+
+| Time | Event | What You See |
+|------|-------|--------------|
+| 0:00 | VM starts | Linux desktop |
+| 0:05 | GPU unbinds | Display goes BLACK |
+| 0:10 | VM boots | Physical monitor shows Windows |
+| 0:15-5:00 | VM running | Windows on monitor, host is headless |
+| 5:00 | Timeout | VM shuts down |
+| 5:05 | GPU restores | Linux desktop returns |
+
+**Success criteria:**
+- ✅ Display goes black smoothly
+- ✅ Windows appears on monitor
+- ✅ VM is usable (install NVIDIA drivers in Windows if needed)
+- ✅ After 5 minutes, VM shuts down automatically
+- ✅ Linux desktop returns
+
+**If something goes wrong:**
+- Via SSH: `sudo virsh destroy win11` (force stop)
+- Via SSH: `gpu-recovery` (restore GPU to host)
+- Check logs: `sudo journalctl -t vm-gpu-start -n 50`

+
+---
+
+## Important Reminders
+
+### ⚠️ Your System Has NO Integrated Graphics
+
+When the VM runs:
+- **Host becomes completely headless**
+- **NO display output from host**
+- **Monitor shows ONLY the VM**
+- **Control host ONLY via SSH**
+
+This is NOT like systems with iGPU where:
+- Host keeps display on integrated graphics
+- Looking Glass shows VM in a window
+- Both host and VM have displays simultaneously
+
+**Your workflow:**
+1. Linux desktop visible
+2. Start VM → display goes BLACK
+3. Monitor shows Windows
+4. Stop VM → Linux desktop returns
+
+### 🔒 SSH is MANDATORY
+
+You MUST have SSH access from another device:
+- Phone with Termux
+- Laptop on same network
+- Another computer
+
+Test SSH BEFORE attempting GPU passthrough!
+
+### ⏱️ Safety Timeout is Your Friend
+
+For testing, ALWAYS use a timeout:
+```bash
+export GPU_PASSTHROUGH_TIMEOUT=5 # 5 minutes
+```
+
+Once you're confident everything works, you can disable it:
+```bash
+export GPU_PASSTHROUGH_TIMEOUT=0 # No automatic shutdown
+```
+
+---
+
+## Next Steps Checklist
+
+- [ ] Run preflight check: `./gpu-passthrough-preflight-check.sh`
+- [ ] Test GPU bind/unbind: `sudo ./test-gpu-bind-unbind.sh 30`
+- [ ] Install hooks: `sudo ./install-gpu-passthrough-hooks.sh win11`
+- [ ] Create Windows VM using virt-manager
+- [ ] Test VM boots without GPU
+- [ ] Add GPU to VM XML: `sudo virsh edit win11`
+- [ ] Validate readiness: `./validate-gpu-passthrough-ready.sh win11`
+- [ ] Set timeout: `export GPU_PASSTHROUGH_TIMEOUT=5`
+- [ ] Have SSH ready on another device
+- [ ] First test: `virsh start win11`
+- [ ] Monitor via SSH: `sudo journalctl -f -t vm-gpu-start`
+- [ ] Verify VM appears on monitor
+- [ ] Wait for automatic shutdown (5 min)
+- [ ] Verify Linux desktop returns
+- [ ] Install NVIDIA drivers in Windows
+- [ ] Test gaming/applications
+- [ ] Adjust or disable timeout as needed

+## Verification Commands Run
+
+```bash
+# Check for old paths without subdirectory
+grep -rn "user_scripts_local" . --include="*.sh" --include="*.md" | \
+ grep -E "(~/|/home/|HOME)" | \
+ grep -v "Single_GPU_KVM_PASSTHROUGH" | wc -l
+# Result: 0 (no old paths remaining)
+
+# Verify all paths include the subdirectory
+grep -rn "user_scripts_local/Single_GPU_KVM_PASSTHROUGH" . --include="*.sh" --include="*.md" | wc -l
+# Result: Multiple correct references found
+```
+
+## All Correct Path Formats
+
+The following path formats are now used consistently:
+
+1. **Absolute paths:**
+ - `/home/coops/user_scripts_local/Single_GPU_KVM_PASSTHROUGH/`
+
+2. **Tilde paths:**
+ - `~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH/`
+
+3. **$HOME paths:**
+ - `$HOME/user_scripts_local/Single_GPU_KVM_PASSTHROUGH/`
+
+4. **$SUDO_USER paths (in root scripts):**
+ - `/home/$SUDO_USER/user_scripts_local/Single_GPU_KVM_PASSTHROUGH/`
+
+## Quick Start (Updated)
+
+All commands now work with the new directory structure:
+
+```bash
+cd ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH
+
+# Check system
+./gpu-passthrough-preflight-check.sh
+
+# Test binding
+sudo ./test-gpu-bind-unbind.sh 30
+
+# Install hooks
+sudo ./install-gpu-passthrough-hooks.sh win11
+
+# Validate readiness
+./validate-gpu-passthrough-ready.sh win11
+```

+# GPU Passthrough Scripts and Documentation
+
+## Quick Start
+
+```bash
+cd ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH
+
+# 1. Check system readiness
+./gpu-passthrough-preflight-check.sh
+
+# 2. Test GPU binding (display will go black for 30 seconds!)
+# Have SSH ready first: ssh coops@10.10.10.9
+sudo ./test-gpu-bind-unbind.sh 30
+
+# 3. If test passes, install hooks
+sudo ./install-gpu-passthrough-hooks.sh win11
+
+# 4. Create Windows VM (follow documentation)
+
+# 5. Validate everything is ready
+./validate-gpu-passthrough-ready.sh win11
+
+# 6. Start testing with safety timeout
+export GPU_PASSTHROUGH_TIMEOUT=5
+virsh start win11
+```
+
+## Available Scripts
+
+### System Checks
+- `gpu-passthrough-preflight-check.sh` - Comprehensive system verification
+- `validate-gpu-passthrough-ready.sh` - Final readiness check before testing
+
+### Testing
+- `test-gpu-bind-unbind.sh [seconds]` - Test GPU binding without starting VM
+ - Example: `sudo ./test-gpu-bind-unbind.sh 30`
+ - Display will go black for specified duration
+ - GPU binds to vfio-pci then returns to nvidia
+
+### Installation
+- `install-gpu-passthrough-hooks.sh [vm-name]` - Install libvirt hooks
+ - Example: `sudo ./install-gpu-passthrough-hooks.sh win11`
+ - Copies hooks to /etc/libvirt/hooks/
+ - Sets correct permissions
+
+### Hook Scripts (in libvirt-hooks/)
+- `qemu` - Main libvirt hook dispatcher
+- `win11/prepare/begin/start.sh` - Runs before VM starts (unbind GPU from host)
+- `win11/release/end/stop.sh` - Runs after VM stops (restore GPU to host)
+
+### Documentation
+- `IMPLEMENTATION-SUMMARY.md` - What has been done and next steps (READ THIS FIRST!)
+- `GPU-PASSTHROUGH-TESTING-GUIDE.md` - Complete testing procedure with troubleshooting
+- `single-gpu-passthrough-guide.md` - Full GPU passthrough guide (updated for no-iGPU)
+- `single-gpu-passthrough-audit.md` - Technical audit findings
+- `README-GPU-PASSTHROUGH.md` - This file
+
+## Safety Features
+
+### Automatic Timeout
+Set before starting VM:
+```bash
+export GPU_PASSTHROUGH_TIMEOUT=5 # Minutes
+```
+
+VM will automatically shut down after timeout, restoring GPU to host.
+
+### Recovery Commands
+```bash
+# Emergency recovery
+gpu-recovery
+
+# Force stop VM
+sudo virsh destroy win11
+
+# Manual GPU restore
+sudo /etc/libvirt/hooks/qemu.d/win11/release/end/stop.sh
+
+# Check logs
+sudo journalctl -t vm-gpu-start -t vm-gpu-stop -n 50
+```
+
+## Important Notes
+
+### ⚠️ Your CPU Has NO Integrated Graphics
+- i7-14700KF has no iGPU
+- When VM runs, host becomes HEADLESS
+- Monitor shows ONLY the VM
+- Control host via SSH only
+
+### 🔒 SSH is MANDATORY
+Test SSH access before any GPU passthrough:
+```bash
+ssh coops@10.10.10.9
+```
+
+### 📊 Monitoring
+```bash
+# Watch VM status
+watch -n 2 'virsh list --all'
+
+# Watch GPU driver
+watch -n 2 'lspci -k -s 01:00.0 | grep "Kernel driver"'
+
+# Follow logs
+sudo journalctl -f -t vm-gpu-start -t vm-gpu-stop
+```
+
+## Workflow
+
+**Normal Operation:**
+1. Linux desktop (GPU using nvidia)
+2. Start VM → Display goes BLACK
+3. Monitor shows Windows (GPU using vfio-pci)
+4. Stop VM → Linux desktop returns
+
+**With Safety Timeout:**
+1. Set: `export GPU_PASSTHROUGH_TIMEOUT=5`
+2. Start VM
+3. After 5 minutes, VM auto-shuts down
+4. GPU automatically returns to host
+
+## Configuration
+
+Current system:
+- VM Name: win11
+- GPU: 0000:01:00.0 (NVIDIA RTX 4090)
+- Audio: 0000:01:00.1
+- Display Manager: sddm
+- SSH IP: 10.10.10.9
+
+Edit hook scripts if your configuration differs:
+- `libvirt-hooks/win11/prepare/begin/start.sh` (lines 10-12)
+- `libvirt-hooks/win11/release/end/stop.sh` (lines 10-12)
+
+## Need Help?
+
+1. **Read documentation:** `IMPLEMENTATION-SUMMARY.md` and `GPU-PASSTHROUGH-TESTING-GUIDE.md`
+2. **Check logs:** `sudo journalctl -t vm-gpu-start -n 50`
+3. **Test without VM:** `sudo ./test-gpu-bind-unbind.sh 30`
+4. **Verify hooks:** `./validate-gpu-passthrough-ready.sh win11`
+
+## Files Not To Delete
+
+Keep these in ~/user_scripts_local/Single_GPU_KVM_PASSTHROUGH/:
+- All .sh scripts (you might need them again)
+- All .md documentation
+- libvirt-hooks/ directory (source for reinstallation)

+# Single GPU Passthrough Guide
+
+Pass your only GPU to a VM on-demand, without breaking host boot.
+
+## ⚠️ Know Your Hardware First
+
+**Do you have integrated graphics?**
+
+Run this command to check:
+```bash
+lscpu | grep "Model name"
+lspci | grep -i vga
+```
+
+**If you see:**
+- Intel CPU ending in **F** (i7-14700KF, i5-13600KF): ❌ **NO** integrated GPU
+- Intel CPU without F (i7-14700K, i9-13900K): ✅ **HAS** integrated GPU
+- AMD CPU ending in **G** (5600G, 5700G): ✅ **HAS** integrated GPU (APU)
+- AMD CPU without G (5800X, 7950X): ❌ **NO** integrated GPU
+- Only one entry in `lspci | grep -i vga`: ❌ Single GPU system
+
+### What This Means for You
+
+| Your System | When VM Runs | Host Display | Best Viewing Method |
+|-------------|--------------|--------------|---------------------|
+| **No iGPU** (F-series Intel, most AMD) | Host becomes headless | ❌ None | Physical monitor shows VM directly |
+| **Has iGPU** (non-F Intel, AMD APU) | Host keeps display on iGPU | ✅ Working | Looking Glass (view VM in window) |
+
+**If you have no iGPU:** Read Step 0 carefully and set up SSH BEFORE attempting passthrough.
+
+## How It Works
+
+Instead of binding the GPU to vfio-pci at boot (which breaks display), we:
+1. Boot normally with nvidia driver
+2. When starting the VM: stop display manager → unbind nvidia → bind vfio-pci → start VM
+3. When stopping the VM: unbind vfio-pci → bind nvidia → start display manager
+
+This is achieved with **libvirt hooks** - scripts that run before/after VM start/stop.
+
+## Prerequisites
+
+- IOMMU enabled in BIOS (VT-d for Intel, AMD-Vi for AMD)
+- libvirt, qemu, virt-manager installed
+- Your VM already configured (we'll add the GPU later)
+
+## ⚠️ CRITICAL: Systems WITHOUT Integrated Graphics
+
+**If your CPU has NO integrated GPU (Intel F-series like i7-14700KF, or AMD CPUs without graphics):**
+
+When you pass through your only GPU to the VM:
+- **Your host display will go COMPLETELY BLACK**
+- The host becomes **headless** (cannot render any graphics)
+- Your physical monitor will show **only the VM's output**
+- You **MUST** set up SSH access for emergency recovery
+
+**This is NOT optional.** Read Step 0 below before proceeding.
+
+## Step 0: Emergency Recovery Setup (MANDATORY for No-iGPU Systems)
+
+### 1. Enable and Test SSH
+
+```bash
+# Enable SSH daemon
+sudo systemctl enable --now sshd
+
+# Verify it's running
+sudo systemctl status sshd
+
+# Get your local IP address (write this down!)
+ip -4 addr show | grep "inet " | grep -v 127.0.0.1
+# Example output: inet 192.168.1.100/24
+```
+
+### 2. Test SSH from Another Device
+
+From a phone (using Termux), laptop, or another computer on the same network:
+
+```bash
+ssh your-username@192.168.1.100 # Use your actual IP
+```
+
+If this doesn't work, **DO NOT proceed** with GPU passthrough until SSH is working.
+
+### 3. Create Emergency Recovery Script
+
+```bash
+mkdir -p ~/.local/bin
+
+cat > ~/.local/bin/gpu-recovery << 'EOF'
+#!/usr/bin/env bash
+set -euo pipefail
+sudo /etc/libvirt/hooks/qemu.d/win11/release/end/stop.sh
+sudo systemctl start sddm # Change to your display manager
+EOF
+
+chmod +x ~/.local/bin/gpu-recovery
+
+# Add to PATH if not already
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
+```
+
+### 4. Test the Recovery Script
+
+```bash
+source ~/.bashrc
+gpu-recovery # Should run without errors
+```
+
+**Recovery procedure if display goes black:**
+1. SSH from another device: `ssh user@192.168.1.100`
+2. Run: `gpu-recovery`
+3. Your display should return
+
+## Step 1: Enable IOMMU (Keep This)
+
+The `intel_iommu=on iommu=pt` kernel parameters are fine to keep. They enable IOMMU without binding anything to vfio.
+
+Verify IOMMU is working:
+```bash
+dmesg | grep -i iommu
+# Should show IOMMU enabled messages
+```
+
+## Step 2: DO NOT Configure Early vfio-pci Binding
+
+**This is what caused your boot issue.** Make sure these are NOT set:
+
+```bash
+# /etc/mkinitcpio.conf - MODULES should be empty or not include vfio
+MODULES=()
+
+# /etc/modprobe.d/vfio.conf - should NOT exist or be empty
+# DELETE this file if it exists
+```
+
+## Step 3: Identify Your GPU's PCI Addresses
+
+```bash
+# Find your GPU
+lspci -nn | grep -i nvidia
+# Example output:
+# 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation AD102 [GeForce RTX 4090] [10de:2684]
+# 01:00.1 Audio device [0403]: NVIDIA Corporation AD102 High Definition Audio Controller [10de:22ba]
+```
+
+Note the addresses: `01:00.0` (GPU) and `01:00.1` (audio). The full PCI path is `pci_0000_01_00_0`.
+
+## Step 4: Create the Libvirt Hooks Directory Structure
+
+```bash
+sudo mkdir -p /etc/libvirt/hooks/qemu.d/win11/prepare/begin
+sudo mkdir -p /etc/libvirt/hooks/qemu.d/win11/release/end
+```
+
+Replace `win11` with your VM's exact name as shown in virt-manager.
+
+## Step 5: Create the Main Hook Script
+
+```bash
+sudo nano /etc/libvirt/hooks/qemu
+```
+
+```bash
+#!/usr/bin/env bash
+#
+# Libvirt QEMU Hook Dispatcher
+# Executes hook scripts based on VM lifecycle events
+#
+set -euo pipefail
+
+GUEST_NAME="$1"
+HOOK_NAME="$2"
+STATE_NAME="$3"
+
+BASEDIR="$(dirname "$0")"
+HOOK_PATH="$BASEDIR/qemu.d/$GUEST_NAME/$HOOK_NAME/$STATE_NAME"
+
+if [[ -f "$HOOK_PATH" ]]; then
+ "$HOOK_PATH" "$@"
+elif [[ -d "$HOOK_PATH" ]]; then
+ while read -r file; do
+ "$file" "$@"
+ done <<< "$(find -L "$HOOK_PATH" -maxdepth 1 -type f -executable | sort)"
+fi
+```
+
+```bash
+sudo chmod +x /etc/libvirt/hooks/qemu
+```
+
+## Step 6: Create the VM Start Script
+
+```bash
+sudo nano /etc/libvirt/hooks/qemu.d/win11/prepare/begin/start.sh
+```
+
+```bash
+#!/usr/bin/env bash

+```
+
+```bash
+sudo chmod +x /etc/libvirt/hooks/qemu.d/win11/release/end/stop.sh
+```
+
+## Step 8: Add GPU to VM Configuration
+
+Edit your VM's XML configuration:
+
+```bash
+sudo virsh edit win11
+```
+
+Add the GPU and audio devices inside the `` section:
+
+```xml
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+Adjust the bus/slot/function to match your `lspci` output (01:00.0 = bus 0x01, slot 0x00, function 0x0).
+
+## Step 9: Restart libvirtd
+
+```bash
+sudo systemctl restart libvirtd
+```
+
+## Step 10: Test It
+
+**Before starting:** Have an SSH session ready on another device, or accept that your monitor will show the VM directly.
+
+### For Systems WITHOUT iGPU (i7-14700KF):
+
+1. **Open an SSH session from another device** (phone/laptop):
+ ```bash
+ ssh user@192.168.1.100 # Your host's IP
+ ```
+
+2. **From virt-manager on the host, start your Windows VM**
+
+3. **Your display will go BLACK** - this is normal! The host no longer has graphics capability.
+
+4. **Wait 30-60 seconds** - your monitor should show the Windows boot screen
+
+5. **Your monitor now displays the VM directly** - use it like a normal Windows PC
+
+6. **To control the host:** Use the SSH session from step 1
+
+7. **To stop the VM:** Either shut down Windows normally, or from SSH:
+ ```bash
+ sudo virsh shutdown win11
+ ```
+
+8. **After VM stops:** Your Linux desktop should return automatically
+
+### For Systems WITH iGPU:
+
+1. Open virt-manager
+2. Start your Windows VM
+3. Your display might flicker briefly
+4. Use Looking Glass or physical monitor to see the VM
+5. When you shut down the VM, your Linux desktop continues normally
+
+### Expected Timeline:
+
+```
+0s: Click "Start" in virt-manager
+2s: Display manager stops, screen goes black
+5s: Hook script completes, VM begins booting
+15s: Windows boot logo appears on monitor
+30s: Windows desktop ready
+```
+
+### If Something Goes Wrong:
+
+**Display stays black after 2 minutes:**
+
+From SSH:
+```bash
+# Check if VM is running
+sudo virsh list --all
+
+# If VM is running but no display:
+# Check VM logs
+sudo tail -f /var/log/libvirt/qemu/win11.log
+
+# Force stop VM and restore display
+sudo virsh destroy win11
+gpu-recovery
+```
+
+**Can't SSH in:**
+
+1. Press `Ctrl+Alt+F2` to try accessing a TTY
+2. Login and run: `gpu-recovery`
+3. If TTY doesn't work, hard reboot (hold power button)
+
+## Viewing the VM Display
+
+Since your GPU is passed to the VM, you need a way to see the VM's output.
+
+**The method you choose depends on whether your CPU has integrated graphics:**
+
+### For CPUs WITHOUT Integrated Graphics (i7-14700KF, AMD F-series)
+
+When the VM starts, your host becomes **completely headless** (no display capability at all).
+
+#### Option 1: Physical Monitor (Recommended - Zero Latency)
+
+**This is the standard approach for single GPU passthrough.**
+
+- Your physical monitor(s) connected to the GPU will display the VM directly
+- When VM starts: monitor goes black → shows Windows boot screen
+- When VM stops: monitor shows Linux desktop again
+- To control the host while VM is running: SSH from another device
+
+**Setup:** None needed - just use your existing monitor(s).
+
+#### Option 2: Network Streaming (Sunshine + Moonlight)
+
+Stream the VM's display to another device over your local network.
+
+**In the Windows VM:**
+1. Download and install [Sunshine](https://github.com/LizardByte/Sunshine/releases)
+2. Configure Sunshine and set a PIN
+
+**On your viewing device (phone/tablet/laptop):**
+1. Install Moonlight client
+2. Connect to the VM's IP address
+3. Enter the PIN
+
+**Latency:** Adds ~10-20ms, suitable for most gaming.
+
+#### Option 3: Remote Desktop (RDP)
+
+**In Windows VM:**
+- Enable Remote Desktop in Windows Settings
+- Note the VM's IP address
+
+**From another device:**
+```bash
+# Linux
+rdesktop
+
+# Or use Remmina GUI
+```
+
+**Latency:** Higher (~50-100ms), not ideal for gaming.
+
+---
+
+### ❌ Looking Glass - NOT Compatible Without iGPU
+
+**Looking Glass REQUIRES the host to have display capability** (integrated GPU or second discrete GPU).
+
+If your CPU has no iGPU (F-series Intel, many AMD chips), Looking Glass **will not work** because:
+- The host cannot render the Looking Glass window (no GPU available)
+- When your only GPU passes to the VM, the host becomes headless
+
+**Looking Glass is only for:**
+- Dual GPU systems (iGPU + dGPU passing through)
+- Systems with multiple discrete GPUs (one for host, one for VM)
+
+If you have an iGPU, Looking Glass is excellent. If not, use physical monitor or network streaming.
+
+---
+
+### For CPUs WITH Integrated Graphics (Most Intel non-F, AMD APUs)
+
+#### Option: Looking Glass (Recommended - Low Latency)
+
+Looking Glass lets you view the VM in a window on your host desktop.
+
+**Install in VM:** [Looking Glass Host](https://looking-glass.io/downloads)
+
+**Install on host:**
+```bash
+paru -S looking-glass # or build from source
+```
+
+**Add shared memory to VM XML:**
+```bash
+sudo virsh edit win11
+```
+
+Add inside ``:
+```xml
+
+
+ 64
+
+```
+
+**Create shared memory file:**
+```bash
+sudo touch /dev/shm/looking-glass
+sudo chown $USER:kvm /dev/shm/looking-glass
+sudo chmod 660 /dev/shm/looking-glass
+```
+
+**Make it persistent (create systemd tmpfile):**
+```bash
+echo 'f /dev/shm/looking-glass 0660 $USER kvm -' | sudo tee /etc/tmpfiles.d/looking-glass.conf
+```
+
+**Run Looking Glass client:**
+```bash
+looking-glass-client
+```
+
+The VM will display in a window on your host desktop.
+
+## Troubleshooting
+
+### Viewing Logs
+
+The hook scripts now log to journald. View them with:
+
+```bash
+# View start hook logs
+sudo journalctl -t vm-gpu-start -n 50
+
+# View stop hook logs
+sudo journalctl -t vm-gpu-stop -n 50
+
+# Follow logs in real-time
+sudo journalctl -t vm-gpu-start -t vm-gpu-stop -f
+
+# View libvirt logs
+sudo journalctl -u libvirtd -n 50
+
+# View VM console output
+sudo tail -f /var/log/libvirt/qemu/win11.log
+```
+
+### VM won't start, display manager keeps restarting
+
+**Symptom:** Display flickers black, then returns to login screen immediately.
+
+**Cause:** Another process is using the GPU.
+
+**Fix:**
+```bash
+# Check what's using the GPU
+lsof /dev/nvidia*
+
+# Common culprits:
+# - Wayland compositors (use X11 instead, or stop compositor first)
+# - Steam
+# - Discord (hardware acceleration)
+# - Chrome/Firefox (hardware acceleration)
+# - Conky or other desktop widgets
+
+# Close those apps, then try again
+# Or add a longer sleep in start.sh:
+sleep 5 # After stopping display manager
+```
+
+### "vfio-pci: failed to bind" error
+
+**Cause:** IOMMU groups incorrect, or device still in use.
+
+**Check IOMMU groups:**
+```bash
+#!/usr/bin/env bash
+for d in /sys/kernel/iommu_groups/*/devices/*; do
+ n=${d#*/iommu_groups/*}; n=${n%%/*}
+ printf 'IOMMU Group %s: ' "$n"
+ lspci -nns "${d##*/}"
+done | grep -E "VGA|Audio"
+```
+
+**Your GPU and its audio device should be in the same IOMMU group, OR in separate groups.**
+
+If other devices (USB controllers, SATA controllers) are in the same group, you have two options:
+1. Pass through ALL devices in that group to the VM
+2. Enable ACS override patch (breaks IOMMU isolation - research first!)
+
+### Black screen after VM shutdown
+
+**Symptom:** VM shuts down, but Linux desktop doesn't return.
+
+**Cause:** Stop hook script failed.
+
+**Fix via SSH:**
+```bash
+ssh user@your-host-ip
+
+# Check if VM is actually stopped
+sudo virsh list --all
+
+# Check logs to see what failed
+sudo journalctl -t vm-gpu-stop -n 50
+
+# Manually run the stop script
+sudo /etc/libvirt/hooks/qemu.d/win11/release/end/stop.sh
+
+# If that fails, manually restart display manager
+sudo systemctl start sddm
+```
+
+**Fix via TTY:**
+```
+Ctrl+Alt+F2
+login
+gpu-recovery
+Ctrl+Alt+F1
+```
+
+### nvidia module won't unload
+
+**Symptom:** Hook script fails with "module nvidia is in use"
+
+**Cause:** Application is using the GPU.
+
+**Fix:**
+```bash
+# Check what's using nvidia
+lsof /dev/nvidia*
+
+# Common issues:
+# - Docker containers using nvidia runtime
+# - Persistent nvidia daemon
+# - Background apps (Steam, Discord)
+
+# Stop nvidia-persistenced if running
+sudo systemctl stop nvidia-persistenced
+
+# Kill processes using GPU
+sudo fuser -k /dev/nvidia*
+
+# Try unloading again
+sudo modprobe -r nvidia_drm nvidia_modeset nvidia_uvm nvidia
+```
+
+### VM starts but no display output
+
+**Symptom:** VM is running (virsh list shows it), but monitor shows "No Signal"
+
+**Possible causes:**
+
+1. **Windows hasn't installed GPU drivers yet**
+ - First boot: Windows uses generic display driver
+ - Install NVIDIA drivers in Windows
+ - Reboot VM
+
+2. **Monitor input not switching**
+ - Manually switch monitor input to the correct port
+ - Try a different cable (DisplayPort vs HDMI)
+
+3. **GPU ROM issue**
+ - Some GPUs need VBIOS ROM dumping
+ - Add to VM XML:
+ ```xml
+
+
+
+
+
+
+ ```
+
+### Check if passthrough is working
+
+**From host (via SSH while VM is running):**
+```bash
+# GPU should be bound to vfio-pci
+lspci -k -s 01:00.0 # Use your GPU address
+# Should show: Kernel driver in use: vfio-pci
+
+# VM should be using the GPU
+sudo virsh dumpxml win11 | grep -A5 hostdev
+```
+
+**From Windows VM:**
+1. Open Device Manager
+2. Look for your GPU under "Display adapters"
+3. Install NVIDIA drivers if not present
+
+## Complete Directory Structure
+
+```
+/etc/libvirt/hooks/
+├── qemu # Main hook dispatcher (executable)
+└── qemu.d/
+ └── win11/ # Your VM name
+ ├── prepare/
+ │ └── begin/
+ │ └── start.sh # Runs before VM starts (executable)
+ └── release/
+ └── end/
+ └── stop.sh # Runs after VM stops (executable)
+```
+
+## AMD GPU Users
+
+Replace nvidia modules with amdgpu:
+
+In start.sh:
+```bash
+modprobe -r amdgpu
+```
+
+In stop.sh:
+```bash
+modprobe amdgpu
+```
+
+## Quick Reference
+
+### System Workflow (No iGPU)
+
+| Action | What Happens | What You See |
+|--------|--------------|--------------|
+| **Boot host** | Normal boot with nvidia driver | Linux desktop |
+| **Start VM** | SDDM stops → nvidia unloads → vfio-pci binds → VM starts | Display goes BLACK → Windows boot screen |
+| **VM running** | Host is headless, GPU in VM | Monitor shows Windows |
+| **Stop VM** | vfio-pci unbinds → nvidia loads → SDDM starts | Brief black screen → Linux desktop |
+
+### Where Is the GPU?
+
+| Scenario | GPU Bound To | Host Display | Monitor Shows | Control Host Via |
+|----------|--------------|--------------|---------------|------------------|
+| Host booted | nvidia | ✅ Working | Linux desktop | Keyboard/mouse |
+| VM starting | (transition) | ❌ BLACK | Nothing | Wait... |
+| VM running | vfio-pci (VM) | ❌ No graphics | Windows VM | SSH only |
+| VM stopping | (transition) | ❌ BLACK | Nothing | Wait... |
+| VM stopped | nvidia | ✅ Working | Linux desktop | Keyboard/mouse |
+
+## Emergency Recovery
+
+If something goes wrong and your display doesn't return, you have several options:
+
+### Method 1: SSH (Recommended)
+
+From another device on the same network:
+
+```bash
+# SSH into your host
+ssh user@192.168.1.100 # Use your actual IP
+
+# Check if VM is running
+sudo virsh list --all
+
+# Force stop the VM
+sudo virsh destroy win11 # Replace win11 with your VM name
+
+# Run the recovery script
+gpu-recovery
+
+# Or manually run the stop script
+sudo /etc/libvirt/hooks/qemu.d/win11/release/end/stop.sh
+
+# Check what went wrong
+sudo journalctl -t vm-gpu-start -t vm-gpu-stop -n 100
+```
+
+### Method 2: TTY Console
+
+If you can't SSH but the system is responsive:
+
+1. Press `Ctrl+Alt+F2` (or F3, F4, etc.) to switch to a TTY
+2. Login with your username and password
+3. Run: `gpu-recovery`
+4. Press `Ctrl+Alt+F1` to return to graphical interface
+
+### Method 3: Hard Reset (Last Resort)
+
+If nothing else works:
+
+1. Hold the power button for 10 seconds to force shutdown
+2. Boot normally - the GPU will bind to nvidia driver as usual
+3. Check logs after boot: `sudo journalctl -t vm-gpu-start -n 100`
+
+### Viewing Logs
+
+Check what went wrong:
+
+```bash
+# Hook script logs
+sudo journalctl -t vm-gpu-start -t vm-gpu-stop -n 100
+
+# Libvirt logs
+sudo journalctl -u libvirtd -n 100
+
+# VM-specific logs
+sudo tail -f /var/log/libvirt/qemu/win11.log
+```
+
+### Common Issues and Fixes
+
+**Display never comes back after VM shutdown:**
+```bash
+# Via SSH:
+sudo systemctl start sddm # Or your display manager
+```
+
+**VM fails to start, display is black:**
+```bash
+# Via SSH:
+sudo virsh destroy win11
+gpu-recovery
+# Check logs to see what failed
+sudo journalctl -t vm-gpu-start -n 50
+```

+# Dusky Update Helper Scripts
+
+These scripts help you manage local changes to tracked files when running dusky system updates.
+
+## Problem
+
+When you run the dusky update, it does a `git reset --hard` to get the latest upstream changes. This can overwrite your local customizations. While the update script stashes your changes, it's not always clear:
+- What you've changed locally
+- What changed upstream
+- Whether you need to merge changes
+
+## Solution
+
+These helper scripts give you visibility and control over the update process.
+
+## Usage
+
+### 1. Before Update: `pre_update_check.sh`
+
+Run this **BEFORE** running the dusky update:
+
+```bash
+~/user_scripts/update_dusky/pre_update_check.sh
+```
+
+**What it does:**
+- Shows all your local changes to tracked files
+- Categorizes them (Hyprland configs, scripts, desktop files, etc.)
+- Optionally shows detailed diffs
+- **Creates a timestamped backup** of all your changes
+- Saves a full diff patch for reference
+
+**Output:**
+- Backup directory: `~/Documents/dusky_update_backups/YYYYMMDD_HHMMSS/`
+- Modified files list
+- Full diff patch
+
+### 2. Run Dusky Update
+
+```bash
+~/user_scripts/update_dusky/update_dusky.sh
+```
+
+The update will proceed as normal, stashing and applying changes.
+
+### 3. After Update: `post_update_merge.sh`
+
+Run this **AFTER** the update completes:
+
+```bash
+~/user_scripts/update_dusky/post_update_merge.sh
+```
+
+**What it does:**
+- Compares your backed-up files with the current versions
+- Detects which files changed upstream
+- Identifies potential conflicts (both you and upstream modified the same file)
+- **Interactive conflict resolution** for each conflicting file
+
+**Options for each conflict:**
+1. Keep current version (from update)
+2. Restore your backed-up version
+3. Open 3-way merge editor (vimdiff)
+4. Skip and decide later
+
+## Example Workflow
+
+```bash
+# 1. Check what you've changed
+~/user_scripts/update_dusky/pre_update_check.sh
+
+# Review the output, see your changes
+
+# 2. Run the update
+~/user_scripts/update_dusky/update_dusky.sh
+
+# 3. Merge your changes back
+~/user_scripts/update_dusky/post_update_merge.sh
+
+# Review conflicts and choose how to resolve them
+```
+
+## File Categories
+
+The scripts categorize your changes into:
+- **Hyprland Config** - Files in `~/.config/hypr/`
+- **Other Config** - Other files in `~/.config/`
+- **User Scripts** - Files in `~/user_scripts/`
+- **Desktop Files** - Files in `~/.local/share/applications/`
+- **Other** - Everything else
+
+## Backup Location
+
+Backups are stored in:
+```
+~/Documents/dusky_update_backups/YYYYMMDD_HHMMSS/
+```
+
+Each backup contains:
+- All modified files (full copies)
+- `modified_files.txt` - List of files that were modified
+- `full_diff.patch` - Complete diff of all changes
+- `metadata.sh` - Timestamp and file count info
+
+## Manual Recovery
+
+You can always manually restore files from the backup:
+
+```bash
+# List backups
+ls -lt ~/Documents/dusky_update_backups/
+
+# Compare a specific file
+diff -u ~/Documents/dusky_update_backups/YYYYMMDD_HHMMSS/path/to/file ~/path/to/file
+
+# Restore a file
+cp ~/Documents/dusky_update_backups/YYYYMMDD_HHMMSS/path/to/file ~/path/to/file
+```
+
+## Tips
+
+- Run `pre_update_check.sh` every time before updating
+- Keep old backups - they're timestamped so you can track history
+- Use the detailed diff option to review your changes before updating
+- For complex merges, option 3 (vimdiff) gives you full control
+
+## Requirements
+
+- `git` (already required for dusky)
+- `diff` (standard on all Linux systems)
+- `vimdiff` (optional, for 3-way merge - install with `pacman -S vim`)
