Sometime in the last few weeks, a Fedora 35 PC that uses the NVIDIA
drivers lost use of its virtual consoles. By this I mean that if I
switch to a VC with <Ctrl-Alt-Fx>, a getty service is started but I
don't see any video: both of the two monitors just go to sleep.
Evidently this has been a common issue with the NVIDIA drivers over the
years but this is my first time to experience it.
[root@calvin ulrick]# rpm -qa 'kmod-nvidia*'
Boot command line:
[ 0.000000] Command line:
root=UUID=1a53e9b9-b298-4dab-8dbe-732b418b4d75 ro rootflags=subvol=root

nvidia_modeset 1167360 7 nvidia_drm
nvidia_uvm 1204224 0
nvidia 39153664 342 nvidia_uvm,nvidia_modeset
I added video=efifb just now. I also tried removing the
acpi_enforce_resources=lax parameter and replacing nvidia-drm.modeset=1
with nomodeset. I also ran 'depmod -ae' in case I was affected by that
issue. None of these fix the issue.
Any suggestions on how I might proceed with troubleshooting this issue?
