Two choices [GNOME, Fedora 14]:
- Use the
- Use the "switch user" function [gnome menu -> log out -> switch user]
So the question is: which one is the safer method to lock the screen if a user leaves the pc?
Is it true that using the  method is safer? The way I see it, the
gnome-screensaver is just a "process", it could be killed. But if you use the log out/switch user function, it's "something else". Using the "switch user" function, could there be a problem like with the
gnome-screensaver? Could someone "kill a process" and presto...the lock is removed? Could the GDM [??] "login windows process" get killed and the "lock" gets owned?
If the  method is safer, then how can i put an icon on the GNOME panel, to launch the "switch user" action by 1 click?
