On other operating systems you can hit ‘e’ in the grub screen which allows you to edit the linux kernel’s parameters. Doing that for qubes OS also brings up a bunch of stuff but I don’t see anything related to ‘linux’. I need this because I’d blacklisted my gpu in grub and was running off my igpu, I can’t use my igpu anymore so I need to un-blacklist it otherwise I won’t be able to boot into qubes.
Edit: Never mind, it turns out you can, you just need to scroll down in the grub prompt
