There's no portable way to do this. You can target a particular screen locker and often times they will have an option or way to send a message to the screen locker to stop locking. Some desktop screen lockers will look for particular power mgmt profiling to determine if they should lock or not.

If you want to disable it permanently, you should be able to do this in System -> Preferences -> Screensaver. Then you could manually lock your screen when you feel it is needed.

Since you're saying RHEL 5.4, you can send the gnome-screensaver a dbus message to inhibit locking with:

Code:

dbus-send --session --dest=org.gnome.ScreenSaver --type=method_call --print-reply --reply-timeout=20000 /org/gnome/ScreenSaver org.gnome.ScreenSaver.Inhibit string:"myshell" string:"I have no reason for doing this"

That command will return an integer string (cookie)... use that to UnInhibit

Code:

dbus-send --session --dest=org.gnome.ScreenSaver --type=method_call --print-reply --reply-timeout=20000 /org/gnome/ScreenSaver org.gnome.ScreenSaver.UnInhibit uint32:<the-integer-returned-from-the-inhibit>
