Force 16:10 w/Gamescope Resolution Control

[Salty Teemo]

Gamescope implementation does not allow user to set game input/output resolution.

Generally you use the following commands in launch options:

-W, -H: set the resolution used by gamescope. Resizing the gamescope window will update these settings. Ignored in embedded mode. If -H is specified but -W isn't, a 16:9 aspect ratio is assumed.

Defaults to 1280×720.
-w, -h: set the resolution used by the game. If -h is specified but -w isn't, a 16:9 aspect ratio is assumed. Defaults to the values specified in -W and -H.
-r: set a frame-rate limit for the game. Specified in frames per second. Defaults to unlimited.
-o: set a frame-rate limit for the game when unfocused. Specified in frames per second. Defaults to unlimited.
-U: use AMD FidelityFX™ Super Resolution 1.0 for upscaling
-n: use integer scaling.
-b: create a border-less window.
-f: create a full-screen window.



I recommend that a quick setting be available in steam deck which applies the following launch option successfully for games that only natively support 16:9.

gamescope -w 1280 -h 720 -W 1280 -H 800 -U -b -- %command%

This should stretch the resolution to 16:10 and remove black bars for those who don't mind vertically stretched games.

Currently this launch option seems to conflict with the gamescope session already running and thus causes games to fail to open with it.

I need this. Been researching but I can't find a way to force some games to run in 16:10.

What about games that use non-standard aspect ratios in general, and not just 16:9?
Some older games in particular only run in 4:3. 3:2 resolutions also exist, though (hopefully) no game should natively support that resolution.

Really hope this becomes a thing! There's lots of games that I'd love to get rid of the black bars of, even if it means stretching or zooming in slightly.
