[Linux] Can't change screen resolution to anything other than my native resolution
When I try to change resolution, in options it says it has been changed, but it actually hasn't, and when I join any game, even in options it shows my native resolution again.

I tried using steam launch options, but again, I did not notice any change, and in options it still shows my native resolution.
