Hi. Have problem with nvidia drivers at ubuntu 20.10. Installed a new system and llast drivers nvidia 460.

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

Have you disabled Secure Boot? If so how exactly have you installed the drivers? Did it work at some point and then this happen or never worked?

[grabasimo]

Secure boot is off. I installed drivers on new system. Yes worked before. Happens after when i upgrade system from 20.04 to 20.10. I tried all drivers (ppa from 418 to 460, drivers from nvidia.com). I update bios and my kernel lost signed. i decide to install new system should work without issues. Even when using nouveau looks it not see nvidia card. just use intel card...




EDIT!

Finally i installed driver and working. I removed all nvidia driver from system (ppa) and dkms. reboot system and without any drivers (ctrl+alt+f3) login to system. install binary drivers from nvidia.com without dkms! after reboot is working.
