I’m trying to setup PCI passthrough for VM and it was going ok until I could no longer load my login screen after blacklisting nvidia graphics. Got an error: [FAILED] failed to start simple desktop display manager. Other services start after that, like radarr, sonarr, but then it gets stuck in console screen and I have to reboot in safe mode.
Do I have to reset SDDM? Do I have to reset xorg? How do I do that? I don’t want to bork my system any worse.
Installed optimus manager and switched to Intel graphics hoping it would fix the issue. Now I can’t boot even in recovery mode.
I tried different display managers, tried logging in in console and running startx, nothing works. “No screens found”. My xorg and display manager must be all screwed up.
At this point I should just reinstall the system, but I’ve managed to lose my installer USB media.
NVidia drivers? Installed the proprietary drivers with pamac, I think. That was a long time ago. Do I just need to uninstall them? I’ve set the KVM modules so that vfio took over the GPU and Intel graphics should be fine. The only thing not working is SDDM (not starting) and X (no screens error).
I can only take pics with my phone. Don’t know how I would be able to upload logs without GUI.
Here’s the kernel line:
Here’s the xorg log:
So, it’s trying to load the NVidia drivers, then trying to load Intel, but can’t and defaulting to previous, which does not show any screens (cause the GPU is disabled/blacklisted)?
Ok… Trying to reset xorg was a bad idea. I deleted everything possible related to xorg/X/X11 and reinstalled. End result is that now even GDM/Wayland doesn’t work and I’m stuck with no GUI again.
After days of scratching my head and trying different things, I reinstalled xorg-xkbcomp and ran X and it worked!!! I had tried pretty much everything before.
