Attach your X server log and config file as individual uncompressed file attachments using the link below. After that, please try the following option in xorg.conf as a diagnostic test: Option "PciOSConfig" "1"
In what section of xorg.conf do I put this option? The available sections are: "ServerLayout", "Files", "Module", "InputDevice", "Monitor", "Device", "Screen" and "DRI".
