Ubuntu 16.04, GNOME shell 3.18.5 I have the same issue. I often meet this issue when I unlock the screen before the black screen returns to the original screen. In short, when I unlock it very quickly, this issue happened.
Screen is successfully unlocked, but the only thing I get is a single mouse pointer and black screen. I can move my mouse, but nothing is on the screen but black. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1285258 Title: sometimes GNOME screen lock fails to unlock after password entered To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1285258/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
