Issues with Gamescope and Steam on openSUSE Slowroll (KDE, X11 and Wayland)

[Brunhylde]

Hi everyone,

I’m experiencing an issue running Gamescope with Steam on openSUSE Slowroll. I’m testing with a lightweight game, Limbo, on KDE Plasma. I’ve tried running it both on X11 and Wayland sessions, but I get the same error in both environments. L’m using the minimal command option : gamescope %command%.

This setup was working a few days ago, but it seems the recent Steam update might have broken something. When I run Steam from the terminal, I see the following messages:

Running gamescope glxgears works without any issues in the terminal. Any help would be greatly appreciated!

Thank you in advance!

Did you read the changelog of the steam update?

"Native titles will execute in ‘Steam for Linux runtime 1.0 (scout)’ by default, instead of the legacy runtime environment. This behavior is consistent with Steam Deck and promotes better compatibility across all Linux desktop distributions. Note that this new feature can be turned off globally with
-compat-force-slr off
on the Steam client command line. "

Does it work, if you start steam with disabled the new feature?
steam -compat-force-slr off

Thank you for the suggestion!

I tried launching Steam with the -compat-force-slr off option, but unfortunately, it didn’t change the result. I’m still encountering the same errors.

Hi all !

Some news. It now works with

gamescope – %command%

It’s even works with :

MANGOHUD_CONFIGFILE=/home/…/MangoHud/MangoHud.conf gamescope -f -h 720 -H 1080 -F fsr --mangoapp – %command%

So, it seems the “–” is important, but it was working without before.

Anyway, tanks again for help !

Thank you for sharing the solution.

Hi,

It’s normal

Hmmm, it’s seems the editor merge sometimes deux minus - and - into – . The correct instruction is with --: gamescope --. %command% without the dot after the 2 minus but a space.
