Hi, I am trying to install the driver for rtx 2070 super on ubuntu 20.04 lts. The driver is installed automatically during system installation (build 440.100). However, after installation it is not possible to enter the graphical interface, there seems to be a conflict with the video card. A purple screen appears and a prompt to enter an authorization password. It was not possible to go further. Tell me a way to solve the problem.
output of lspci -d 10de:* -nn

This rather sounds like you enabled disk encryption or secure boot module signing and now it asks for the password you were required to create for it.
That’s right, but the password doesn’t work. If i remove the nvidia driver, the GUI loads.
Is this an ASUS mainboard? Some of those have a bios bug so importing the signing key doesn’t work.
amd msi X570-A pro
UEFI+Legacy bios mode
Does it work if you run
sudo mokutil --disable-validation
to disable validation and afterwards install the driver?
driver is installed now. I see that with nvidia-smi
sorry, I didn’t see the MOK window on the first try. Now i disabled security boot, but purple screen still with me :)
I really don’t know what kind of screen you’re stuck and which password it asks for. Rather try installing Ubuntu 18.04, 20.04 has some ugly bugs that need to be ironed out.
