Arch Linux User Repository

Hello, I made a guide to integrate this package into an SDDM+KDE environment if anyone is interested. https://www.reddit.com/r/archlinux/comments/1p2fmso/comment/nqjvr44/

The only thing I can't get working are these settings that are completely ignored :

# Set the specific values allowed for refresh rates
CUSTOM_REFRESH_RATES=40,50,60
# Set the range of the refresh rate slider in the Steam client
export STEAM_DISPLAY_REFRESH_LIMITS=40,60

EDIT 29/07/2025: My bad, it works out of the box, I should have not overriden CLIENTCMD environment variable. The steam command line option -steamdeck is required in order to show the 4 different levels of performance details (included in the default CLIENTCMD value). Then, with a DualShock 4 Controller, in game, I just have to press PS button + X and the performance overlay appears at the right of the screen. This is so cool.

Hi!

Anyone knows how to enable mangohud in a dedicated gamescope session with this package? Some environment variables to set in ~/.config/environment.d/gamescope-session-plus.conf?

Or any working ways to display a performance overlay?

Thanks.

You need to use "gamescope-session-plus steam".

Best of luck!

The service file doesn't seem to work for me.

@ripplingsnake switch to desktop and a game mode shortcut are out of the scope of this package. It is not possible to do this in general as it requires a very specific configuration, including autologin configured and a known session manager and desktop environment.

See how it is done in ChimeraOS (lightdm + Gnome) by taking a look at these files:

• https://github.com/ChimeraOS/chimeraos/tree/master/rootfs/etc/lightdm (lightdm configuration)
• https://github.com/ChimeraOS/chimeraos/blob/master/rootfs/usr/share/applications/org.chimeraos.session-return.desktop (game mode shortcut)
• https://github.com/ChimeraOS/chimeraos/blob/master/rootfs/usr/share/wayland-sessions/gnome-session-oneshot.desktop (special one off gnome session - so that switching to desktop/gnome is not permanent)
• https://github.com/ChimeraOS/chimeraos/blob/master/rootfs/usr/bin/gnome-session-oneshot (see above)
• https://github.com/ChimeraOS/chimeraos/blob/master/rootfs/usr/lib/os-session-select (the script called by Steam when switching to desktop)

@xiota addressed your comments, thanks.

I have this and gamescope-session-steam git the problem is when selecting switch to desktop it doesn’t . Steam shuts down and the the gamescope session restarts. What have I missed to get it to exit to desktop? Also there is no return to game mode desktop shortcut I can find. Thanks

gamescope-git at least requires libliftoff but isnt a runtime dependency. Insstalling that package let it work for me.

Currently using SDDM, Plasma Wayland, gamescope-session-git and gamescope-session-steam-git. You also need glfw-x11 installed to satisfy mangoapp dep (included with manohud package)
