I have an older nvidia card (1070) and had more of an issue than that getting the correct version of the driver installed for my card, and getting it to use the correct driver instead of the open source one that didn’t work well. It’s also possible I was doing something wrong. But yeah, it’s definitely doable, and it’s not too bad, but it’s fiddly compared to the ubuntu driver gui or something like bazzite that works out of the box with it.




It’s going to be a total re-install, so that depends on what kind of setups you have. Not really different than switching to/from another distro.
Bazzite ships with KDE, so you could likely copy your themes and customizations for that pretty easily.
Bazzite is fedora based, and doesn’t use apt, but you can use distrobox like I mentioned in my post to get familiar ubuntu packages, if there are things that you need to be not flatpaks. You also can probably copy config files from non-flatpak apps into the flatpaks for most apps. I did this with my Cura configs. It may depend on the application.
Basically, I just backed up my user folder (~/) and pulled any configs out of there. You could just back up ~/.config and ~/.local but with ubuntu there are likely some things in a snap directory and such. Mainly ~/.config and ~/.local, but some applications may use other directories, like snap, etc.
