I recently got a good deal on a W540 i7-4800MQ with NVIDIA K2100M, and it’s running Qubes 4.1 with the 5.14.63-1.fc32 kernel, for the most part, without any issues. The only major problem I am experiencing is that sometimes the audio will stop working after disconnecting a secondary display via the Mini Display Port or the VGA. I cannot always replicate the problem, and a reboot will solve the issue.
I have checked the PulseAudio control and everything indicates that it’s working and is not on mute. I can only guess this is due to the NVIDIA K2100M taking over when a second display is detected.
If I understand correctly, Qubes doesn’t work well with NVIDIA. Therefore, I would like to persistently disable the NVIDIA graphics to see if NVIDIA is the culprit. Would anyone know the best way to disable the NVIDIA graphics, so it will only run on the integrated Intel HD 4600 graphics?
If any other W540/W541 users out there have a similar experience, I would be grateful for any tips. Thank you.
