Fix "Unknown Chipset" with nouveau
Raw
fix.md

Booting from a Linux installation disk with a newer graphics card might trigger an "Unknown Chipset" error from nouveau.

Add nomodeset nouveau.modeset=0 to the kernel options to fix it.

In UEFI Boot Mode it might also hang at "Triggering uevents", which is the same issue without the error message.

Hello, I have the same error. I tried applying your solution, but nothing changed. I still get the message "unknown chipset."
Is what I entered and where I entered it correct?
