🖥️ System Information
Laptop: ASUS TUF Gaming F15 FX506LHB_FX506LHB (1.0)
Environment: Wayland + Hyprland (Omarchy setup)
Kernel module involved: asus_wmi, asus_nb_wmi
Backlight device: /sys/class/leds/asus::kbd_backlight
❗ Problem Description
When using keyboard backlight controls via:
Fn + Super + Arrow Keys (Up / Down / Left / Right)
the SUPER (Windows) key stops functioning correctly.
Observed behavior:
SUPER + Enter (launch terminal) stops working
SUPER key sometimes becomes completely unresponsive
Issue persists even after turning backlight OFF
Behavior is inconsistent — sometimes SUPER works again after some time or reboot
Additional issue:
Breathing mode (via Fn + Super + Left/Right) does not work properly
🔁** Steps to Reproduce**
Boot into Hyprland (Omarchy setup)
Confirm SUPER + Enter works
Press: Fn + Super + Up / Down (keyboard backlight control)
Try: SUPER + Enter
❌ Expected Behavior
Keyboard backlight changes
SUPER key continues to function normally
✅ Actual Behavior
Backlight changes successfully
SUPER key stops working as a modifier
All SUPER + key bindings fail
State persists even after disabling backlight
Key finding:
The problem is caused by ASUS firmware behavior triggered via asus_wmi, not Hyprland or Wayland.
✔ Stable workaround
Avoid firmware-triggering path
Control backlight via:
/sys/class/leds/asus::kbd_backlight/brightness by cmd echo 1 | sudo tee /sys/class/leds/asus::kbd_backlight/brightness
