NVIDIA driver not functioning with GUI

Hello, We are having problems with our NVIDIA GeForce RTX 2080 Ti. We have successfully downloaded and set up its driver (Version 460.32.03) and upon startup at terminal screen it works just fine. We check with nvidia-smi. However, as soon as we activate the GUI via systemctl start lightdm the screen starts glitching constantly and the computer is uncontrollable. When the native Intel GPU is chosen, the problem does not occur.

OS details:

Ubuntu 18.04.5, kernel: 4.15.0-51-generic

Any help will be appreciated and happy to provide more details.

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Dear generix, thanks for your reply! I have updated my post as requested. The bug report was generated from the terminal at the startup screen when nvidia gpu was running.

Here is the bug report after we try initiating gui from terminal when the nvidia gpu is running.

As soon as the Xserver starts on the nvidia gpu you’re getting all kinds of XID errors across the board. This looks like defective hardware, please

  • reseat the gpu board in its slot (pull it out, put it back in)
  • check system memory ( remove memory modules one-by-one, check if crashes appear )
  • run gpu-burn to test the gpu
  • check if the gpu works in another system

Thanks a lot for checking it and for the advice. Will do all of the mentioned points and update the results here.

Just to give an update for others encountering the same issue, we proved in fact that it was a hardware issue. Replacing it with a different GPU output 0 gpu_burn errors as compared to millions of the previous one.

Thanks for the help.
