`gamescope` is slowly becoming the hammer to all of my gaming or recording issues on Linux PC.
Doesn’t capture in OBS via obs-vkcapture? Gamescope.
Get’s ideas about screen layout? Gamescope.
Has no built in FSR? Gamescope.
Doesn’t show up in the list for screenshare? Gamescope.
Does this post need a hashtag? #gamescope.
I usually play #FlyDangerous on Linux PC. I switched to Proton because I was eager to see some upcoming changes, like #headtracker support, on the public_beta branch. And while this works I was once more flabbergasted how complicated it is to set my desired display resolution of 5760×1200. I’m using a multihead setup with several displays and as usual the game engine would not let me _simply_ set that. Even in windowed mode (I mean I get that this won’t work with fullscreen).
There are several ways to work around this, especially with Proton, but I was looking for the prefs file I know from Linux. I found it in the end in the file compatdata/1781750/pfx/user.reg (that’s like the Windows registry but as plain file read by Wine) where the values are stored as dword under [Software\\StarGoat\\FlyDangerous]. In hex.
"Screenmanager Resolution Height_h2627697771"=dword:000004b0
"Screenmanager Resolution Width_h182942802"=dword:00001680
"Screenmanager Resolution Use Native_h1405027254"=dword:00000000
So 0780 and 04b0 are in the end 5760 and 1200. And sure enough, on the next game start I get _my_ desired resolution:
Sadly when I change settings in the game this gets overwritten again – so keep a backup around and drop it in again. This may even be added to a script – let’s see how long until this gets on my nerves and I automate that.
For the interested: This is how the same thing looks on the native version in the file ~/.config/unity3d/StarGoat/FlyDangerous/prefs
