The whole problem started when I tried to connect to the GPU in order to get the correct version of cuda. Unfortunatly it didn’t work and I ended updating the driver as mentionned in the error code. Using Ubuntu 20.04 and Titan GPU I removed the current driver (460.xx, remove + sudo autoremove) and installed the recommanded one (470.xx). The installation went fine but when i reboot I am stuck on a blinking black screen with a cursor. I tried many things like removing installing another version, modified the kernel nomodeset (i have access to the terminal), enabling/disabling waylands, The commands nvidia setttings and nvidia-smi are not working. I can’t acess the bios and I don’t know if uefi could be the cause of this problem. Attached to this post is the bug report if someone can help. If more info are needed do not hesitate since i already spent many hours on that problem.
