It doesn't change anything with A11 BIOS and 3.5.0-44. Step: 1. Boot to desktop, plug the D-Sub cable, make sure the external display works 2. Close the lid
Expected results: * System could be suspended Actual results: * both display on external monitor and laptop screen were off, but it was not suspended. Power LED was not blinking, and if you move the external mouse with lid closed, the external display will be back. sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date A11 08/27/2013 ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1195148 Title: 10de:11bc [Dell Precision M6700] With external monitor plugged, this system cannot be suspended by closing the lid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1195148/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
