Bob, Probably some of the OpenGL screeensavers are causing the crash. For immediate relief, set a single screensaver (don't let xscreensaver cycle through the list). You can use xscreensaver-demo to do this. You can also use xscreensaver-demo to manually cycle through the screensavers to confirm this is the problem. I've got this happening on any multiscreen (matrox) machines with GLX support enabled in /etc/X11/XF86Config. My solution has been to comment out these lines in /etc/X11/XF86Config: # Load "GLcore" # OpenGL support # Load "glx" # OpenGL X protocol interface # Load "v4l" # Video4Linux Then the OpenGL stuff can't crash the Xserver.
