Comment 18 for bug 154104

This problem still exists for me. I have a Samsung X20 with a mobile 915G integrated graphics controller.

Until about last week, compiz-fusion worked fine using the normal xserver-xorg. After some updates (the "normal" ones coming out of the standard repositories!), compiz-fusion stopped working and complains in the following way:

mneisen@samsumm:~$ compiz --replace
Checking for Xgl: not present.
Detected PCI ID for VGA: 00:02.0 0300: 8086:2592 (rev 03) (prog-if 00 [VGA])

Checking for non power of two support: present.
Checking for Composite extension: present.
Comparing resolution (1400x1050) to maximum 3D texture size (2048): Passed.

Checking for FBConfig: present.
Checking for Xgl: not present.
Starting kde-window-decorator
/usr/bin/compiz.real (core) - Fatal: No GLXFBConfig for default depth, this isn't going to work.
/usr/bin/compiz.real (core) - Error: Failed to manage screen: 0
/usr/bin/compiz.real (core) - Fatal: No manageable screens found on display :0

If I install XGL, compiz will work, but it is unbearingly slow - and it wasn't that slow until last week. Plus, I have noticed that my GFX card has no direct rendering any more:

mneisen@samsumm:~$ glxinfo | grep direct
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
OpenGL renderer string: Mesa GLX Indirect

I would appreciate if someone could sort this out. If you need any additional information, please do not hesitate to ask.
