[Solved] Try this - unlocking screensaver without a password
A blog post at aeroxteam.fr initially uncovered and detailed this apparent vulnerability. A commit to XKB for X.Org Server 1.11 adds a few debug key actions for grabs and the window tree. One of the four new XKB actions allowed is killing clients with active grabs, which is what most (or perhaps all) desktop environment screensavers rely upon for their screensaver lock -- just ensuring they have the top window and are catching all input events. One of the other four options is unleashing all active grabs. While a debugging feature, both of these are appearing by default in some of the leading Linux distributions.
Try it, lock your screen then press ctr+alt+<numpad *>. It works for me (xscreensaver/xfce)
