I recently encountered an issue with my Ubuntu 20.04 setup after attempting to upgrade CUDA from version 10.1 to 11.4. After the upgrade, I noticed that the nvidia-smi command was no longer functioning properly. In an attempt to resolve the issue, I ran ubuntu-drivers autoinstall, but unfortunately, this caused my system to stop booting normally. Now, I can only boot into recovery mode.

I've tried reinstalling Ubuntu 20.04 and 22.04 while using safe graphics mode (the try and install option led to a black screen), but this hasn't resolved the problem. It seems that I'm still stuck with the issue. Has anyone else faced a similar problem or have any suggestions on how I can get my system back to its normal state?

Edit

I've noticed an interesting detail that might be relevant. The command ubuntu-drivers list lists nvidia-340 among the drivers. However, when I try to remove it using sudo apt remove nvidia-340, I receive the message: Package 'nvidia-340' is not installed, so not removed.

I've identified the solution to my issue. I realized that I have a GeForce 210 graphics card inserted into my motherboard. After reinstalling Ubuntu, the Nouveau driver was automatically activated. However, the graphics card cannot communicate with the nouveau driver through VGA, and this resulted in a black screen.
