I switched to Linux as my daily driver back last summer and have been able to play every game I've tried with literally no issues. Admittedly, I had issues at first but then I switched to Pop!_OS, which has built-in support for Nvidia hybrid graphics. That solved the few gaming issues I had.
With how easy it was and how many games work with no issues, I'm genuinely surprised to hear people say they are having issues with it. I'm not even close to a linux expert. I'm not a programmer. I don't want my OS to be a hobby, I want it to just work. And so far it has.
Do you still do this by just pressing enter when you change your password? (i.e. entering no password as your password)
