Keyboard media keys (Fn + F keys, eg. vol mute, +/-, brightness etc.) do NOT yet work in mainline kernel. There is some good work going on over here on github but it’s preliminary.

Also note kernel 6.10 broke the bottom display it would appear; I’m using kernel 6.13-rc4 currently.

If you happen to be trying to do this on a laptop with dual-graphics and the GPU is NVIDIA, it took me a while to find that one often can get proper GPU support by adding this just before wine (as in, right before it on the same command line):

__NV_PRIME_RENDER_OFFLOAD=1 \
  __GLX_VENDOR_LIBRARY_NAME=nvidia wine <game .exe> ...

NEW METHOD which avoids the udev ‘event storm’ caused by docking/undocking the keyboard

[/usr/local/bin/asusUX8406_kbdwatch]

#!/bin/bash

me=$(basename "$0")
laststate=2

while true; do
  sleep 3
  output=$(lsusb -d 0b05:1b2c)
  stat=$?
  if [ $stat == 1 ] && [ $laststate != 1 ]; then
    ## kbd removed, enable lower display
    laststate=1
    logger -p user.info "${me} KEYBOARD REMOVED"
    xrandr --auto && xrandr --output eDP-2 --below eDP-1
  elif [ $stat == 0 ] && [ $laststate != 0 ]; then
    ## kbd replaced, disable lower display
    laststate=0
    logger -p user.info "${me} KEYBOARD DOCKED"
    xrandr --output eDP-2 --off
  fi
done

Hook this up to your init system, or run from a nohup session redirected to /dev/null on login or session startup … for example, on my system I am member of group video, so installing it to /usr/local/bin and setting ownership to root:video and sudo chmod ug+rx allows it to be run on session login automatically.
