Switching VTs has no effect, tried several times just now. Killing the unity-panel-service resolved it again. I usually have to kill -9 it, then a new one respawns, then I kill that one normally, and the lock screen generally reappears then.
I'll install today's driver update and recheck next time it occurs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1418295 Title: Black screen after resuming from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1418295/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
