Mac Mini 2020 M1 keyboard problem (some key combinations doesn't work)#466

I installed Asahi Linux 3 weeks ago and have been trying to find a solution since then, but without success.

I am using a Windows keyboard on both Asahi Linux and macOS. When I press CTRL+SHIFT+P, CTRL+SHIFT+U, or CTRL+SHIFT+K, the key combinations are not recognized. All three keys work correctly when pressed individually or with other modifier combinations.

These key combinations work properly on macOS with the same keyboard.

System info:

  • Distro: Fedora Linux Asahi Remix 42 (KDE Plasma Desktop Edition)
  • Kernel: 6.18.15-400.asahi.fc42.aarch64+16k
  • Device: Mac Mini M1 (2020)
  • Keyboard: USB Windows keyboard (Vendor: 0c45, Product: 760a)

What I have tested so far:

  • sudo evtest — CTRL+SHIFT+U/K/P produces no output at the kernel level
  • sudo libinput debug-events — same result, no output for these combinations
  • xkbcli interactive-wayland — no output for these combinations
  • Killed all IBus processes — issue persists
  • Normally using Turkish (tr) keyboard layout. Switched to us layout to test — issue persists
  • Wayland is in use, X11 is not available
