I can use compiz, but I cannot use decorations in it at 16bpp-resolution: windows decorations are just disappeared. At 24bpp-resolution compiz works with decorations.
Driver works right, xorg works right, but in xsession-errors:
/usr/bin/compiz.real (core) - Warn: No GLXFBConfig for depth 32
/usr/bin/compiz.real (resizeinfo) - Warn: Bind Pixmap to Texture failure

What is GLXFBConfig and how to configure it to use as I use it before in Ubuntu Linux 7.10, 8.04?
I was trying to change xorg.conf, but nothing helped.
