I have an nVidia Corporation GeForce 6800 GT graphics card. I recall reading somewhere there were problems with some nVidia cards an SuSE 10. I really don't understand what I get from the nVidia proprietary software that is installed by the YaST script. Do I need the xorg-x11-server-glx-6.8.2-100.i586.rpm? Would it make any difference if it were installed or not? The reason I asked is that I just built OpenSceneGraph and when I ran it I got this message: Warning: Producer::RenderSurface, under the X11 environment has tested the glXWaitVideoSyncSGI extension and found it to not be working properly. This does not necessarily mean that glXSwapBuffers will not block on VSYNC, but it does mean that the CPU bound application will not be able to synchronize with the graphics video retrace signal. Most operations will work fine. Steven
