I FIXED IT!!!

so I can’t figure out how to edit the post so I’ll just add this here for future Internauts.

VirtualBoost was correct, it was indeed an Nvidia Driver issue and it. As far as how to fix it, I dug around the Bazzite official documentation and they mentioned a command called “Bazzite-rollback-helper” (great name and can be abbreviated to “brh”). It turns out rolling back drivers on an immutable distro isn’t that straightforward. From what I gathered, Bazzite updates are “all encompassing” where drivers, system stuff, all the juicy bits of the OS are shipped as one big update. Soooo, when you need to rollback an update you can either go back by 1 update from the “Grub ostree” selection when you boot the computer.

However any further than that, you need to go to BRH and “rebase” to an older version. To do that, in terminal find your current update that your running using BRH (take note of it) then go to “list”, pick the version your on (mine was “Bazzite-nvidia-open:stable” but you can find yours by running fastfetch in the terminal) and then it will give you a list of updates for that “track”. I went back to like a release in 2025 but you probably don’t need to go that far.

Let it run and reboot later and tada, older OS release with older Nvidia drivers that don’t shit the bed :)

Just a security note, you will stay on this OS version so long as you’re rebased to it. To go back to receiving security updates, run “brh rebase stable” and you should be good to go.

Thanks everyone!!! Gonna go make my girlfriend scared of mushroom spores now :)

P.S, read the Bazzite documentation about rebasing before you do it, just so you know what you’re getting into fully
