Troubleshooting

Name is not activable

Is the daemon running?

systemctl status cardwired.service

If it’s not running, enable the daemon with systemctl enable cardwired.service and reboot your device.

is the asus MUX enabled?

asusctl armoury list

then find

gpu_mux_mode:
  current: [(0),1]

0 means that the MUX is enabled, the dGPU IS the default GPU in this case

This shouldn’t happen, please create an issue with the output of

ls /sys/class/drm

and

cat /sys/class/drm/*/status
