[nvidia] After update display resolution is only 640X480

[Michael Ehrlich]

After a normal software update, the display is no longer recognized. Only resolution offered is 640X480. I think the update did something to the nvidia 460 driver. Tried using the 450 driver, no change. tried going back to 460, no change. I had a very stable systen before update.

It sounds like the Nvidia driver is not happy with the new kernel.

Please try booting an older kernel or forcefully reinstalling the Nvidia kernel driver:

  sudo apt install --reinstall nvidia-dkms-460

and then reboot.

You can also find other kernels to test at https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D

Let's track this is bug 1919285 because it seems pretty similar.
