I guess that heavily depends on the games you’re playing

I think this is the key thing.

If you’re always buying the newest GPU to play the latest tech- envelope-pushing AAA title that requires the latest greatest driver, then you’re probably not going to have a good time with gaming on Debian.

But some of us don’t care about those types of games, or maybe in some cases we do but are willing to wait a while to play a particular title (hello Patient Gamers). In that case Debian is a nice, rock solid gaming platform.

Anecdotally, I probably do 85+% of my gaming on Debian (the rest being my steam deck). And it works fine for me because of the types of games I play and/or how long I tend to wait before getting new titles (giving Debian time to catch up).

It’s definitely not for every gamer, but I don’t think it’s as unusable for gaming as people often suggest.

If you want true for empty strings, you want -z not -n

if [[ -z "VARIABLE1"  && -z "VARIABLE2"  ]]; then
    echo "OK"
