I have the same error on Pop!_OS 21.10

Likewise on Manjaro 5.15.41-1 Nvidia 2080 with driver version 510.73.05

I do not see a device named "VIRTUAL1" and am getting the above error with every other device in the dropdown.

Same error on EndeavourOS; Kernel 6.1.7-arch1-1 Nvidia GT640; drive ver. 470xx

I tried with other screen resolutions, it worked in a very buggy way, but then it stopped working completely.
