Started happening to me recently, but only sometimes when I close the lid and suspend that way. Reminds me of the bug that still occurs on my old HP laptop that's caused by the GNOME screensaver.
Here is the report I managed to collect with apport when I entered this black-screen void state by switching to another tty and running ubuntu- bug. ** Attachment added: "Apport report" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/966744/+attachment/3254741/+files/apport.xorg.DJzp_q.apport -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/966744 Title: Resume from suspend leaves me with black screen or a screen of the desktop before it suspended (though the mouse still moves/changes cursor) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/966744/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
