for compiz I had to run it as:
$ LIBGL_ALWAYS_INDIRECT=true compiz --replace --indirect-rendering

as running 'compiz --replace' I get:
ompiz (core) - Fatal: GLX_EXT_texture_from_pixmap is missing
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0

maybe the problem has something to do with this.

Dear kwin people,

I can't get kwin's (last svn version) desktop effects to work on a dell m1330 with a intel video card...
Every window get a strange color and I have to revert settings
Also get some GLXUnsupportedPrivateRequest on kwin's output when desktop effects is enabled.
Xorg log attached
