Thanks for the bug report. It appears your Nvidia kernel driver is not
loading anymore so low resolution is expected. This may have been caused
by a recent kernel update. Please try this:
sudo apt install --reinstall nvidia-driver-510/jammy
sudo apt install --reinstall nvidia-dkms-510/jammy
** Description changed:
I often have to forcibly power down my PC because of this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1970808. Well, the
most recent time I did that, when the computer restarted, the resolution
is stuck on 1024x768 even though I am on a 1920x1080
