Zorin OS 15 (ubuntu 18.04) Unclaimed GTX 475


I am running Zorin OS 15 (Ubuntu 18.04) and I think my computer don’t recognizes my graphic card (NVIDIA GeForce GTX 475).
This is the result of lshw -c display:

PS: I have try to update my driver multiple time, they appear in my driver list, but my card is still recognize as “llvmpipe (LLVM 10.0.0, 256 bits)”

[ 0.009282] secureboot: Secure boot enabled

Disable secure boot in the BIOS.

Make sure the nouveau driver is blacklisted.


Thanks for the quick response !
I’m totally new to linux (I start using it 2 days ago), can you tell me how to do those things please ?

Go into your computers BIOS and look for Secure Boot → disable it.


I disable the Secure Boot and it works totally fine now !

Thanks a lot for your time, have a nice day !
I will mark you answer as solution, I hope it’s enough to close this topic.

Thanks again !
