Like everybody else who is a linux-head, I'm really excited about the fact that Steam now ships with built-in support for playing non-native titles on Linux via Proton.
When I went to try it out on my relatively new Manjaro install today, however, it uh... it just wouldn't launch. This is after I woke up to having no internet connection because I updated my kernel and didn't have a built version of the driver for my wifi adapter under this particular kernel.
Anyway, I think Steam was just having some kind of issue updating, because after a fresh reinstall it worked... after I restarted my computer. That's something I always forget to do on linux these days because more often than not (especially lately) I'm doing sysadmin stuff on remote servers where the issue is always me being new and not "hey have you tried restarting it." I guess I'm happy that I've learned enough that my problems have circled back around to the same kinds of problems sane, non-power users have.
