It might be worth trying this: - reproduce the problem - disconnect the VGA - login on a text console via ctrl+alt+f1 - run "xrandr -display :0.0 > xrandr.txt" - run "sleep 10;xrandr -display :0.0 --auto --verbose >> xrandr.txt 2>&1" - within 10 seconds, switch back to X with ctrl+alt+f7 - wait 10 seconds and see if that has any effect (what it *should* do is turn the built-in screen back on). Regardless, it would be useful to get the resulting xrandr.txt file and see what it says. -- - mdz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/747205 Title: [arrandale] Black screen on all outputs when external VGA is connected -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
