Comment 14 for bug 1963805

I have found a temporary fix that has seemed to resolve the issue for me. I haven't had a crash or freeze in a while. Though, I am not sure of the overall effect. Use at your own risk:

freeavagames posted a somewhat odd looking solution that does indeed stop the error. Reproduced here for those that do not want to click the link:

"""
( Ubuntu 22.04.1 Nvidia 525.60.11 Kernel: 5.15.0-56-generic )

I have the line “options nvidia-drm modeset=1” in three files:

grep --include=*.conf -rnw ‘/’ -e “nvidia-drm” 2>/dev/null

“/usr/lib/modprobe.d/nvidia-kms.conf:3:options nvidia-drm modeset=1”
“/etc/modprobe.d/nvidia-graphics-drivers-kms.conf:3:options nvidia-drm modeset=1”
“/etc/modprobe.d/nvidia-nomodset.conf:1:options nvidia-drm modeset=1”

If the lines are commented out, the error message disappears.
If you leave this uncommented in at least one of the files, the error message will appear again.
"""

I hope for a full fix but in the meantime this has at least made my computer usable again.
