Re: [gdm-list] gdm desktop selector

Davide:

What version of GDM are you using?  You can tell by running either one
of the two following commands:

$ gdmflexiserver --command=VERSION
$ gdmflexiserver --version

Note that GDM was rewritten for GDM 2.21 so the interfaces for doing
things is different for the two versions.

If you are using a recent version of GDM, note that GNOME bugzilla bug
#602663 adds a "first-time login helper" which is designed to help
autologin users pick their session/language choices.  Perhaps building
GDM with this patch might do what you want.

  https://bugzilla.gnome.org/show_bug.cgi?id=602663

Another option might be to use the GDM "Init" hook to pop-up a GUI
dialog asking the user to enter their choices.  To make this work
you would obviously need to write the GUI program to do this.  Note
that the GDM login process will block until the Init script finishes.
So if the Init script launches a GUI, the login process will hang until
the GUI is finished running.

Note that GDM saves the user's session/language choices in the
following files:

- $HOME/.dmrc
- /var/cache/gdm/(user)/dmrc (in more recent versions of GDM)

So, if the program launched from the Init script sets up the
above file(s) properly, then it should start the session selected
in the GUI you launch.

Information about the "Init" hook is in the GDM documention in the
"Configuration" section.  You should reference the version of the
documentation that relates to the version you are using.  The
documentation is here:
