I have an Ubuntu 20.04 system which has been working perfectly with an nvidia 1080Ti card.
I recently allowed the software updater on ubuntu to install some pending updates and my nvidia card stopped working.
I did not upgrade to ubuntu-20.04 from a previous version of ubuntu. This system has been running ubuntu-20.04 for a while with no issues, and I just allowed some updates to be installed.
Only one of my three attached monitors works now and when I run the nvidia-settings app, I get a small blank screen instead of seeing the nvidia settings listed.
I think this is because nvidia driver is not loading anymore :
$ sudo prime-select query nvidia $ nvidia-smi NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
Here is some additional information which may assist in diagnosing what is wrong:
$ dkms status nvidia, 460.39, 5.8.0-45-generic, x86_64: installed (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING!
