Out of curiosity, what distribution have you been using lately instead of Debian?

Anecdotally, I've been using Fedora Workstation for a few years already, and my Steam + Proton Experimental experience has been fantastic with an AMD GPU using the drivers that come with the kernel.

Although I must admit, I miss having a Debian-based distribution sometimes, because in some situations I can't find rpm packages for more specific things I'm trying to do in my system. The problem is I just don't know any other distribution that's not Debian Testing that could work like Fedora Workstation but with .deb packages.

Fedora Workstation (42)

I add flathub.org and remove the fedora flatpak repo. The few other things I need are in copr/terra, but honestly they are very rare. I think I have maybe 1 piece of software per thing that doesn't release a native .rpm (ghostty is one)

When it comes to Steam, I go to steam -> settings -> compatibility -> Enable Steam Play for all titles

I have used Nvidia GPUs and more recently switched to an AMD 6700. No issues with either.
