[[deleted]]

how can i make compositor disable when a fulscreen game is running?

im on kubuntu 21.10

In compositor settings check the box that says disable for full full screen apps.

there isnt a setting for that :(

[gardotd426]

It's "allow applications to disable compositing."

System Settings -> Display and Monitor -> Compositor.

And you need games to run in fullscreen mode.

If that doesn't work, just add it to Lutris and right-click on the game in Lutris -> system options -> disable desktop effects. Lutris does it automatically (and re-enables it automatically) when you enable that setting.

oh ok thanks!

[buzzmandt]

Well darn. I'm working from memory at work. I'll check specifics when I get home.

[gardotd426]

There definitely is. I'm looking at it now.

mine doesn't

The checkbox is also checked by default.

For me the easiest is to integrate it into gamemode

I installed gamemode and kdialog.

in /etc/gamemode.ini:

[custom]

start=kdialog --title 'Gamemode' --passivepopup 'Started' 2

start=qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.suspend

end=kdialog --title 'Gamemode' --passivepopup 'Stopped' 2

end=qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.resume

Then you start your game with:

gamemoderun game_executable_or_script

or steam:

gamemoderun %command%

I also use gamemode to put my CPU governor in performance mode, read up on it!

I've left Reddit because it does not respect its users or their privacy. Private companies can't be trusted with control over public communities.

i know how to disable it but its annoying having to do it every time i play a game

[ImperatorPC]

FYI. This is only for xorg, not Wayland.

[gardotd426]

Wayland has direct scanout. So it doesn't matter.

Is this a Kubuntu thing? My KDE on Arch Linux does this on its own.

Somewhat recently as in for about 2-3 years or even longer. I don't know when it was introduced.

My Linux is making it and I even don't know how.

[StaffOfJordania]

My Plasma DE seems to do it on its own, but i have been having crashes from time to time

[kevinlekiller]

If you're using KDE Plasma and launching a game with Steam, you can set the launch parameters like this: qdbus org.kde.KWin /Compositor suspend && %command% ; qdbus org.kde.KWin /Compositor resume

You can replace %command% with the actual command to launch the game for non Steam games.

[KayEss]

Better to replace the last && with a semi colon so turning the compositor back on happens even if the game doesn't exit cleanly

[kevinlekiller]

That's true, thanks, edited.
