I actually had my most difficult time ever setting up Linux on my 5800X3D and 3070 recently.
PopOS wouldn't save my resolution on reboot, and then after fixing it all of my games were running at the wrong resolution or breaking in various frustrating ways. All Linux native games too. Jumped to Fedora and every single game flickered like mad and then once I got that fixed my package manager inexplicably broke. I was about to install Ubuntu before saying fuck any chance of instability and going to Debian.
I had to manually install way more than any of the other distros, but everything just worked once I got my graphics driver installed. I was really disappointed given I've been using Linux on and off for 8 years, and my Steam Deck has been nothing but solid. I'm honestly just disappointed things have trended in a bad direction, and I hope this was just a one off experience and not the norm now.
