The problem seems to be related to compiz. After I switch to a terminal, and killall -9 compiz, and switch back to X, I can see a partially functional desktop, because I can't switch between applications, and window frames are missing. It's not recoverable even after restarting compiz with DISPLAY=:0 compiz &.
Restarting lightdm definitely fixes the issue. -- 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/linux/+bug/966744/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
