Edward, do you have an Nvidia card? I have managed to pin the problem down to the Nvidia driver.
When the Nvidia driver is loaded, the screen locks black, and I cannot see the terminal on tty1 (i.e. ctrl+shift+F1 results in black screen), however I can return to X11. If I *don't* load Nvidia then everything is fine. I can close the laptop lid, I can switch to tty1. Here is the diff between the xorg.conf that gives no errors and the one which loads Nvidia: 41,42c41,46 < Section "Device" < Identifier "Configured Video Device" --- > Section "Module" > Load "extmod" > Load "type1" > Load "freetype" > load "glx" > load "v4l" 44a49,52 > Section "Device" > identifier "Configured Video Device" > driver "nvidia" > EndSection I have attached both files as well as the xorg.conf I normally use (i.e. the one I was using in 7.10 without hassles). What is the next step in bug reporting? ** Attachment added: "xorgs.tar.gz" http://launchpadlibrarian.net/14057972/xorgs.tar.gz -- Screen locks up black on laptop lid close. https://bugs.launchpad.net/bugs/49521 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
