Hi everyone, My problem is that my Nvidia Graphic Card is not recognized since a few days. I’ve got this return form lspci, I don’t understand why my Card is shown has that lspci -vnn | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation UHD Graphics [8086:9bc4] (rev 05) (prog-i…

Please try running sudo prime-select nvidia and reboot. Also, please try if you can manually load the driver sudo modprobe nvidia

Prime-select nvidia didn’t work. The other command return : modprobe: ERROR: could not insert ‘nvidia’: Key was rejected by service

sudo dkms remove nvidia/460.39 --all This command returns : Error! There are no instances of modules: nvidia 460.39 located in te DKMS tree. I don’t know if i have an instance of this module, and what version is mine, do you know how can I get the information ?

Please post the output of dkms status

Please try adding the graphics drivers ppa and re-install the driver from there.

According to this: https://askubuntu.com/questions/1323913/all-resolution-options-except-1024x768-gone-after-upgrade-to-ubuntu-20-04-2-lts there should be new ubuntu updates released that fixes the situation.

dkms status return this : nvidia, 460.56, 5.8.0-45-generic, x86_64: installed Nice, thanks for the info and for your help, I’m really grateful
