I’ve been doing some experimentation with creating a GPU VM. In the process of doing so, I installed the package
xorg-x11-drv-nvidia in a standalone VM based on fedora-33. The package was installed from rpmfusion-nonfree.
After doing that, I rebooted the VM and now I am unable to run anything. I don’t know if Xorg is actually running, but I cannot get any application to run anymore.
My expectation was that nothing would change, since the qubes Xorg instance should be using the configuration from
/etc/X11/xorg-qubes.conf which always specifies the qubes drivers. In other words, I expected the nvidia drivers to exist, but not affect the existing configuration at all.
How can I debug this? What I want to find out is what changed in the boot process to prevent Xorg from running with the same configuration as before?
