Logging out of scologin
When you end your Graphical Environment session and log out of the system,
scologin runs a ``reset'' script, called
/usr/lib/X11/scologin/Xreset. This script executes
as root and removes the session manager property
from the Root window.
You can also use this script to undo the effects of commands that were executed in the Xstartup script. For example, the Xreset script could unmount directories from a file server that were mounted when the session was started.
When a Graphical Environment session is terminated, scologin resets the X server and redisplays the scologin window.
