Screen resolution issue in Focal 20.04LTS

Asked by Jaime Cruz on 2021-02-20

I've been a user of Ubuntu since Precise 12.04LTS. Focal is the first time I am using Ubuntu without the Unity desktop (I installed it under Bionic, but my tests under Focal indicated too much was "broken" and even the Ubuntu Unity project has failings). Understand, I don't know if the issue is with Focal, or with the Gnome desktop but I've discovered if I play a game that goes into "Full Screen Mode" under a different resolution than my desktop, when the game ends and I return to the desktop the resolution remains the same as the one set by the game. I have to go into Settings -- Display and change the resolution back manually.

This occurs when I play the native Linux version of Rise of the Triad, Dark Places (Quake engine for Linux) or DOSBox. This was never a problem under Unity; the desktop always reverted back to the correct settings once the game ended.

Running Focal 20.04.2LTS with no proprietary drivers installed. The last time I needed proprietary drivers was with Precise; since then all LTS versions have run just fine with the open source drivers on my system.

You could make a script to run the game, then when it ends use xrandr to set the resolution back. It's a work around but should be OK.

Thank you for that work-around. I'll have to give it a shot. It would be nice if the Gnome developers would address it though; I can't imagine I'm the only person experiencing this.

Can you help with this problem?
