Affects: gnome-screensaver (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
gnome-screensaver no longer fades at all when locking the screen. I was
pleased when dapper first transitioned over to gnome-screensaver as the
fade seemed to be more smooth. Now it does not fade at all. Is this just
a simple ./configure option in debian/rules?
