If it helps any, I too am getting this and I've been using "gcore" to generate a core file from the Xorg process.
I have two nVidia G-series video cards: * GeForce 9400 GT - this drives "screen 1" (middle) * GeForce 8600 GT - this drives "screen 0" and "screen 2" (left and right) My xorg.conf section that defines this: Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" Screen 2 "Screen2" RightOf "Screen1" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "1" EndSection In my case, it locks up at the border between screens about evenly so I don't think it's strictly a Screen0:Screen1 border issue... I'm running a fully updated Ubuntu 10.04, and I'm able to install any developer tools to assist in debugging and/or dumping the core file data.
