I’ve tried both 460 and 470, using the ppa and without it. In either case I have to use prime-select to switch from nvidia to intel (not sure why it tries to select nvidia since the Tesla T4 has no display capabilites). If I don’t use prime-select intel, the machine boots to a blank screen.
I’ve reviewed several of the posts here regarding this error and cannot find anything that solves it. any help is appreciated!
There is no sign of the driver trying to load.
Please first try sudo update-initramfs -c -k all and reboot.
If that doesn’t work, please switch to nvidia with sudo prime-select and then reboot. If you get a black screen, try to switch to a virtual console (Ctrl+Alt+F3) and run nvidia-bug-report.sh as root.
If you don’t get a console, reboot and run journalctl -b1 >kernel.txt and upload that file.
Thanks for pointing me in the right direction! After a few more steps I was able to get this working. After update-initramfs, there was no change. I then ran:
$ sudo prime-select nvidia
After a reboot, it went to a black screen again. I used ctrl-alt-f3 to get to the console. I was then able to run nvidia-smi and the driver was loaded correctly. I then assumed the problem is that it is trying to use the Tesla T4 as the display device.
Afterwards, I found instructions on how to use the integrated graphics unit on Ubuntu 20.04, and everything is working:
$ sudo prime-select on-demand
Then, I followed the instructions here to select the intel:
