Comment 7 for bug 493573

The 12/7 update for gnome-screensaver did not, as expected, fix this issue with xfce.
If xfce is not going to be adapted, and gnome-screensaver is not going to be reverted, then switching to xscreensaver (or to Ubuntu) seems to be the only workaround for the time being (but based on what I've read, there might be some minor issues after doing this, like the "lock screen" buttons not working anymore).
I would appreciate a statement from Canonical on this matter.
