I remember being excited when I saw the first beta test of KDE but it seemed each version got a little bit worse after that and that's been the trajectory of the Linux desktop since 1995 or so.
awk, grep, tail, nginx and all that kind of stuff is fine.
(I tried taking the 1050 card from my media server I used for AI training long ago and put it in another cheap Linux box and put SteamOS on it. They claim it can run Windows games but it won't run anything out of my steam account including the games that the proton database claims works. That's the kind of brokenness as the expected condition that is endemic to the Linux GUI)
If I found a GUI app worked on Linux I'd be so surprised I'd have to file a feature report with their feature tracker.
Xorg has worked for decades, a multitude of window managers and desktop environments have been perfectly usable for decades, and a couple of million people (going by Steam HW survey results) seem to be able to run games via proton perfectly fine.
Doesn't mean you have to think it's perfect, doesn't mean you have to use it for everything, but 'can't use any GUI app on linux' is definitely a you problem.
