NVidia driver stops working after a while on Ubuntu 18.04

NVidia graphics driver (460.xx) stops working after a while on Ubuntu 18.08.
It fork just fine for a while but then ‘nvidia-smi’ outputs that it is gone. Reinstalling it helps but
then situation repeats. It can work for days before this happens.

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

Thank I didn’t know about this. Will definitely do it next time problem arise.

Hi, I have a similar problem. Things were working fine until a reboot, then these problems occurred:

  • only one out of my two monitors were detected
  • the output of nvidia-smi is the following:
    NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I attached the bug report!

You used the runfile installer without dkms to install the driver so it gets lost on kernel updates.
Please uninstall the runfile driver, then use “Software&Updates” to install the driver from repo.
