naegling23 already asked in 2008, but i really would like to know it too. could any1 tell me what to write in the konsole, would like to use it in a script...
or is setting it with "kwriteconfig" and than "kwin --replace" the only "easy" way???

check compositing state with
'qdbus org.kde.kwin /KWin compositingActive'
returns "true" when active
toggle it with
'qdbus org.kde.kwin /KWin toggleCompositing'

This is a really nice plasmoid. Thanks it makes it so easy to toggle on and off composite it is incredible. Thank you!!!

Any chance of making the revert changes dialog appear *after* compositing has been turned on (as it does in System Settings)? Sometimes, KWin takes too long to refresh, so the dialog vanishes before I'm able to accept the changes.

This is the single most useful plasmoid I have come across to date! Especially useful for gamers who (sadly) get better FPS when kwin compositing is disabled.

Thankyou for taking the time to create this, and keep up the good work :).

Thank you just what I was looking for

some artefacts. Please look at screenshot

When put into a panel, it doesn't save position when plasma restarts. I got it between task manager and pager. When restarting it goes right twice, between tray applet and show dashboard.

It would be nice to have an option to remove the border when put on the dashboard, too.

This is great!!!
Just what i need!

There http://www.recast1.com/trash/plasma-applet-toggle-compositing_0.2.3-1_i386.deb kubuntu i386 package.

Contact me if you want to get it.

I found that on KDE 4.2 it's not keeping it's size. When adding it it's quite small, if I resize the panel, it corrects it's size, but on a reboot, it is back to being small again.

Should be fine now.

This is a wonderful widget, and I really enjoyed using it! Thank you!

The bad news is I was able to compile this for 4.2 Beta 2, Kubuntu 8.10; however, and the widget fails after an update to 4.2 RC 1, and cannot be recompiled:

=======================================
CMake Error at /usr/share/kde4/apps/cmake/modules/FindPlasma.cmake:13 (message):
FindPlasma.cmake is deprecated. Now with KDE 4.2 Plasma is part of kdelibs
and automatically found using find_package(KDE4) instead.

Replace the variables previously coming from FindPlasma.cmake as follows:

PLASMA_OPENGL_FOUND -> KDE4_PLASMA_OPENGL_FOUND

PLASMA_LIBS -> KDE4_PLASMA_LIBS

PLASMA_INCLUDE_DIR -> KDE4_INCLUDE_DIR or KDE4_INCLUDES, should be already
set anyway

PLASMA_FOUND -> nothing, it's always there if KDE4, version 4.2 or newer
has been found.

If you see this error message in a module within KDE/, update it from svn,
it has been fixed already.

Call Stack (most recent call first):
CMakeLists.txt:5 (find_package)
=======================================

Somewhat related bug in KDE (where unsupported widgets crash plasma):
https://bugs.kde.org/show_bug.cgi?id=172996

You can get a version that compiles with 4.1.96(4.2RC1), here:
http://ivplasma.googlecode.com/files/toggle-compositing-0.2.2.tar.gz

I would update the links, but currently there seems to be some bug or change in
the kde-look.org site code, that prevents me from doing it.

Thank you for the new build. It indeed compiles on my system (KDE 4.2 RC 1), and so far works beautifully!

I hope you can update the link soon. Thanks again.

Is it possible to add action to change between kwin and compiz ??

Not about your applet, your applet works perfectly

KDE 4.1.85, kubuntu 8.10

Hi,
I think this little tool is simply great.Really good job.
I have recently upgraded from hardy 8.04 to 8.10 and a lot of the applets are not working,it seems to me (my linux mojo is limited) that the files are not found by plasma, maybe.

Can you please help me out ?

Thanks a lot.

Thanks for a nice, simple and effective way to manage compositing in KDE 4.1 without going through the rigmarole of going to KDE control center. Two thumbs up :-D

Is it posible to make the button semi-stransparent? (like glass)?
Very usefull!

Simply by switching plasma theme.

Ebuild is here - http://sonylaptoptools.sourceforge.net/ebuilds/toggle-compositing-0.2.1.ebuild

This plasmoid is good when i whant switch off the compositing before start my preferred Quake3 based games :D

Nice Job!
