Description karaluh 2010-02-03 11:58:53 UTC 
Version:            (using KDE 4.4.0)
Installed from:    Ubuntu Packages

When i go to Desktop in System settings the resume compositing button is available, then after about two seconds and some flicker all the options are greyed out. glxgears works, glxinfo|grep rendering - direct rendering: Yes

what is your graphics card, driver and version?
Comment 2 karaluh 2010-03-01 09:26:15 UTC 
It is Intel integrated GPU, lsusb:

00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)

/var/log/Xorg.0.log:
(II) LoadModule: "intel"
(II) Loading /usr/lib/xorg/modules/drivers/intel_drv.so
(II) Module intel: vendor="X.Org Foundation"
        compiled for 1.7.5, module version = 2.9.1
        Module class: X.Org Video Driver
        ABI class: X.Org Video Driver, version 6.0

I just had a look at the driver check methods and it looks like we don't enable compositing for Intel 8x cards. You can try to disable the functionality checks in the advanced desktop effect dialog
Comment 7 karaluh 2010-03-02 09:06:20 UTC 
The "Advanced" tab is greyed out, I cannot even activate it.
Comment 8 Thomas Lübking 2010-03-02 16:37:20 UTC 
close the kwin compositing kcm (notably the "configure windows" dialog or systemsettings)

then edit ~/.kde/share/config/kwinrc, find the [Compositing] section and set:
DisableChecks=true
Enabled=true
OpenGLIsUnsafe=false

next maybe call "qdbus org.kde.kwin /KWin reconfigure" and reopen the config dialog, pray that it won't segfault ;-)
Comment 9 karaluh 2010-03-04 08:16:07 UTC 
Ok, compositing works and doesn't even crash, but is sluggish. It feels like I'm on fglrx and agp ati card. Is this why this intel chipset isn't supported? Is there anything I can do to improve the compositing experience, like file a bug on freedesktop or something?
