GV100 lost the drivers

the GV100s lost the Nvidia drivers. it looks like the Nvidia Drivers are still loaded but we are unable to run the nvidia-smi command or the access the control panel etc.
I tried to reload the drivers both thru the Desktop updates and manually on the command line. I even tried to purge and uninstall, and then re-install. No luck.
any suggestions?

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

You’ve set your system compiler to llvm/clang so on kernel update, the driver didn’t compile. Please set it back to the standard gcc 9.4 and use dkms to recompile the driver
sudo dkms install nvidia/510.54

Thanks for the information. can you maybe give me a little more detail, on how to change the compiler back to gcc. thanks


generix, thank you for all your help and your patience.
