Please run "apport-collect 900111" to attach more information. It would be nice to also have the "xrandr --verbose" output from the "blind" session.
BTW, I saw this in the log. Do you have the proprietary nvidia OpenGL libraries installed? [ 81272.142] (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found) BTW2: The misleading lspci information would need to be rectified at http://pciids.sourceforge.net/ I might look into this some day, since I also have some other IDs to fix up. Is there any model identifier on the card itself, or in the BIOS messages? ** Changed in: xserver-xorg-video-mga (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/900111 Title: X server on Matrox g550 is all black (no output) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-mga/+bug/900111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
