Yes, I was having these same issues on mint. Literally everything else has worked fine, the most trouble I had was fixing the audio output, and that just took a few minutes.
I saw the power settings comment, when I get home I’m gonna test that and the graphics settings, just tinker with things to see if the suggestions I’ve gotten so far work. Switching distros will be my hail mary if all else fails.
I see, then yes: I installed steam with the built-in software manager. Thanks for the tip about Flatseal, I’ll be sure to look into it after work!
