Public bug reported:
## Summary
After BIOS update to version FX608JHR.309 (2026-01-28), the Super key stopped
working on Linux. The asus_wmi driver receives scancode 0x4f but has no mapping
for it, logging "Unknown key code 0x4f".
## Hardware
- Model: ASUS TUF Gaming F16 FX608JHR
- BIOS: FX608JHR.309 (2026-01-28)
## Software
- OS: Ubuntu 24.04
- Kernels tested: 6.14.0-37 and 6.17.0-22 (both affected)
- asusd: v6.1.21
## Root Cause
BIOS 309 added a new WMI event in the DSDT ACPI table:
Case (0x31) <- WMI internal event
{
If (ATKP)
{
^^^ATKD.IANE (0x4F) <- scancode sent to asus_wmi
}
}
The scancode 0x4F is not present in the asus_wmi/asus_nb_wmi keymap,
resulting in:
asus_wmi: Unknown key code 0x4f
## Evidence
dmesg:
[22.271983] asus_wmi: Unknown key code 0x4f
evtest /dev/input/event8 (Asus WMI hotkeys):
Event: type 4 (EV_MSC), code 4 (MSC_SCAN), value 4f
Event: type 1 (EV_KEY), code 240 (KEY_UNKNOWN), value 1
Event: type 1 (EV_KEY), code 240 (KEY_UNKNOWN), value 0
Note: The key is emitted as instant down+up (~10 microseconds apart),
making it impossible to use as a modifier key even with userspace remapping.
## Expected Behavior
Scancode 0x4f should map to KEY_LEFTMETA (Super/Windows key).
## Proposed Fix
Add the following entry to the asus_nb_wmi keymap in
drivers/platform/x86/asus-nb-wmi.c:
{ KE_KEY, 0x4F, { KEY_LEFTMETA } },
## Additional Notes
The key generates instant down+up events (not sustained hold), which suggests
the BIOS may need to be fixed as well to properly report key hold state.
A BIOS fix would be needed for modifier combinations (Super+L, Super+arrows)
to work correctly.
