Ubuntu 20.04.2 LTS uses llvmpipe (LLVM 11.0.0, 256 bits) instead of Nvidia card

Hello there,

for some reason llvmpipe (LLVM 11.0.0, 256 bits) is used instead of my 1060Ti. I have already tried several solutions like installing the latest drivers, changing the GRUB config etc. but hopefully someone here can help me.

Disable secure boot.

Thanks a lot!
