Re: [gdm-list] custom display on gdmgreeter

[Brian Cameron <Brian Cameron Sun COM>]

Ishaaq:

Most people use zenity for a simple progress bar, and other
kinds of dialogs.  Zenity has a zillion arguments so you'll
probably need to play with a little bit to get to do what you
want.

Look in the "Configuration" section of the GDM documentation that
corresponds with the version of GDM you are using:

  http://library.gnome.org/admin/gdm/

Note the "Init" script allows you to launch a program that runs
with the GDM login GUI.  The "PreSession" script can be used to
launch a program that starts with the user session.  Perhaps this
would be a good hook to launch a program you want to run to
monitor for the sync.  Though if you want a program to start
up in the user session, starting it via $HOME/.profile would
also probably work.

Note that with the "Init" and "PreSession" script, you have to run the
program in the background with the "&" character.  So if you want to
run zenity you would run "zenity --options &" from the script.  If you
leave out the "&", then the script will hang until the launched program
exits.

Good luck,

Brian
