Just to add a confirmation it happens here too (Dapper, current). If gnome-screensaver locks during the rest break, unlocking it when i'm back blocks the unlock dialog (goes gray without any input possible).
"killall gnome-screensaver" from the VT shows me a (presumably) workrave gray fullscreen (no trace of "rest break text" of buttons). I killall workrave from the VT, screen is back normal. => I have to killall *both* to get back to usable screen. -- workrave hangs after unlocking with input blocked https://launchpad.net/bugs/20070 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
