For me it is like this: Window-->ubuntu(a month)-->kubuntu(a week)-->Opensuse tumbleweed

I also tried Nobara, zorinos, arch and bazzite but never actually use them

The name of the pkg is plasma-welcome now you can use dnf to delete it

For Nvidia GPU, if u want squeeze the most out of it during gaming. I think there is 2 best options Bazzite(it is immutable so it will be really hard to break) or Nobara. Both of them is fedora base, so unfortunately your familiar with Debian based will not do much.

ty i gave up to do this long time ago until i found out your post
