Thanks for your reply.
My current problem is that I can’t uninstall the current broken driver. Last time, I used UI to upgrade driver to the latest version. Hence, I don’t know where the .run installers are. Don’t know how to use --uninstall.
I run “sudo apt install nvidia-driver-430”, and got the message
. "nvidia-driver-430 is already the newest version (430.26-Oubuntu0.18.04.2)
. 0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded
Unfortunately, I have the blank screen now after signing in on UI.
Is there anyway I can uninstall the prior Nvidia driver without using --uninstall option because I don’t know where is the .run file? The other way is to figure out a way to find the .run file and run --uninstall option.
Thanks in advance. I think once I uninstall the broken driver and follow your instruction, I will be able to use CUDA.
Note: I have attached my blank screen and the result of running the command “sudo apt install nvidia-driver-430”
