toggle compositing?

[Naegling23]

I know that there is a plasmid to toggle compositing in kde4, so I know that it is possible, but I dont know exactly how to do it.

I would like to make a script to turn off the compositing features (like transparency, wobbly windows, shadows, etc) to better performance when Im playing a game. Something along the lines of the compiz script,
kwin --replace
launchgame&&
compiz --replace

but for kde's compositing effects. Does anyone know what I would put here?

I would also like to know the answer to this question. Have you made any progress Naegling?

well, I did stumble across the following command:

kwriteconfig --file kwinrc --group Compositing --key Enabled false

I found it in the following thread:
http://forum.kde.org/showthread.php?tid=6712

The only problem is that I cant seem to get it working in a script....maybe you can help me out here.

i guess thats what u looking for:
#!/bin/bash
### gamers-composite-disabler for KDE
# Small script that sets kwin as the window manager
# and then executes YOUR GAME. For use with kwin's compositing

# set to FALSE, doesnt matter it was false or true before
kwriteconfig --file kwinrc --group Compositing --key Enabled --type bool false
kwin --replace & #restart kwin for changes to take effect
sleep 2 #wait 2 seconds before excecute, dont know if its really necesary
/media/games/ut2004/ut2004-64 &&
sleep 2
kwriteconfig --file kwinrc --group Compositing --key Enabled --type bool true
kwin --replace &
and thx alot for the link-post :)

Well, in KDE4 if you just want to toggle compositioning, you can do it with dbus calls.

$ qdbus org.kde.kwin /KWin toggleCompositing

Neat and fast.
