The are a variety of reasons why gnome-screensaver is not unlocking, and I suspect you each have a different reason. I am closing this bug, as there is no way to diagnose it.
There are some debugging tips here: https://wiki.ubuntu.com/DebuggingScreenLocking If you still have unlocking issues with a recent release of Ubuntu, please file a new bug. Thanks. ** Changed in: gnome-screensaver (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/181065 Title: Unable to unlock the screensaver -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
