I've got this problem with Nvidia driver for a few months now. Here is what I am usually doing:

I stop gdm3 (sudo service gdm3 stop), install driver with sudo ./NVIDIA-Linux-x86_64-418.74.run --no-x-check, then following instructions, then blacklisting noveau using blacklist-nouveau.conf file - it contains blacklist nouveau and options nouveau modeset=0 then I install cuda, cudnn etc... Everything works properly including nvidia-smi, I can run code on gpu (some NN models in tensorflow). After few reboots my driver breaks down. I boot into login screen set in 800x600 resolution without option to change it. nvidia-smi reports it cannot connect to driver. Then I reinstall driver and then it works for a while, but after few reboots it breaks down again.

Few times I reinstalled everything completely, including Cuda etc., no change in behavioer, however. Any idea what can be wrong?

  • I had the same problem using Nvidia Driver version 430.26. I installed the version 430.26 and ignored the warnings,it was working fine but after few days I upgraded the system to newer kernel and the problem was the same with the resolution. I reinstalled Ubuntu and using the Graphic Driver from apt-repository seems to be fine for now.. btw check this -> Automatic Install using PPA repository to install Nvidia Beta drivers in https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-ubuntu-18-04-bionic-beaver-linux – kannzzmm2 Jun 22 '19 at 11:55
  • Thank you, I'll try that! However, I am afraid that Beta drivers will not work properly with Cuda. Do you have any experience with that? – I-L-P Jun 22 '19 at 12:03
  • I dont have experience with that, but based on this https://askubuntu.com/questions/1077061/how-do-i-install-nvidia-and-cuda-drivers-into-ubuntu it seems to work using the repository ppa:graphic-drivers/ppa – kannzzmm2 Jun 22 '19 at 12:44
