Just a shot in the dark. Is direct rendering on? glxinfo | grep rendering Note : You can still run glxgears without 3d rendering. Could you give more information on the error please.

I have Nvidia 8400GS card with driver installed and enabled (it means that I get glxinfo and glxgears output), but compositing or any 3D games don't work (some openGL error). But at the same time I gan run simple 3D applications like glxgears. Also Nvidia driver starts correctly on startup (logo comes up) and compositing is enabled in xorg.conf. > So any ideas on my problem? Might it be a 64 bit system issue? Just to add, under Ubuntu compiz and games worked just fine. > > Thanks, > Verner. > > > -- ---- www.cern.ch/ribalba / www.ribalba.de Email / Jabber: ribalba@xxxxxxxxx Phone (Work) : +41 22 7679376 Skype : ribalba Address : CERN / IT-FIO-FS / GENEVE 23/ SCHWEIZ
