OSXFAQ Mac OS X Tip-of-the-Day 
System Tricks - Snapshot of the Login Screen
By Adrian Mayo - Editor - OSXFAQ
It is not possible to take a snapshot of the login screen because the
necessary service is not running. However using some terminal trickery
it is possible.
We need to issue a delayed 'screencapture' command, with a delay long
enough to allow us to logout. Moreover, that command must not be
killed (or HUPped) when the issuing shell exists. Finally, the command
must be issued a root because the Aqua screen at login is owned by
root.
So we have:
$ sudo -s
Password:(admin password here)
$ nohup bash -c "sleep 60; screencapture ~/Pictures/screen.pdf"
Change the delay (60 seconds above) as necessary.
Enjoy !! :-)
