[Bug 22681] Re: No way to lock screen after sleep

[Joolz]

after upgrading breezy to dapper on one of three machines gnome-
screensaver will not activate. Not after the timeout and not when
invoked explicitly (lock screen). For me this is a major issue since at
my work mostly i have several root terminals to servers open and need to
lock the workstation when i leave for a moment.
