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)

@wustdsh I've got the same issue. I can still launch gamescope from a tty, but gamescope session just starts and nothing else happens.

My Gamescope session cmd:

/usr/bin/gamescope -e --xwayland-count 2 -O *,eDP-1 --default-touch-mode 4 --hide-cursor-delay 3000 --fade-out-duration 200 -R /run/user/1000/gamescope.AlRBZeP/startup.socket -T /run/user/1000/gamescope.AlRBZeP/stats.pipe

I am starting with greetd display manager:

[terminal]
# The VT to run the greeter on. Can be "next", "current" or a number
# designating the VT.
vt = "next"

# The default session, also known as the greeter.
[default_session]

# `agreety` is the bundled agetty/login-lookalike. You can replace `/bin/sh`
# with whatever you want started, such as `sway`.
command = "agreety --cmd openbox"

# The user to run the command as. The privileges this user must have depends
# on the greeter. A graphical greeter may for example require the user to be
# in the `video` group.
user = "media"

[initial_session]
command = "gamescope-session-plus steam"
user = "media"

@lgdsgd, I'm having the same issue right now. It seems to be connected to locale and is specific to KDE Plasma 5 over Wayland, as far as i could have gathered. No clue, as of yet, how to fix this though
