Urgh, I can confirm this behavior. The "unredirect-fullscreen-window" option does not matter it works for both disabled and enabled.
The expo shortcut key does not work so at least this is not exploitable in the default install (we don't assign expo to a mousebutton by default). I looked at the screensaver code and it looks like there is a active pointer grab when the unlock dialog is up. -- expo allows bypass of screensaver https://bugs.launchpad.net/bugs/247088 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
