Function keys stopped working after last update on Lenovo 300 usb keyboard

I’ve been using Majaro for around two months and I didn’t have any problems with fn key combinations (volume control, sound player control). After the yesterday’s update these combinations stopped working but the output of sudo showkey shows the key codes of fn+(f1,f2…). I updated kernel from 5.10.102-1 to 5.15.25-1 but it didn’t help. Is it possible to make these fn key combinations work again? Here is the output of inxi -Fxza:

Hello @Danil :wink:

Normally these keys are hardcoded in the firmware and not changeable. So Linux could not disable it in my view.

  • Maybe you switch a trigger somewhere in the UEFI-Settings or there was a reset?
  • Are the shortkeys disabled in the Settings of the UEFI or XFCE?
