Re: [gdm-list] problem with autologin on multiple displays

Jeff:

cc:ing gdm-list gnome org, since I think people will be happy to
hear how to hack GDM to support autologin on multiple displays.
Many people have asked for this feature.

Great, glad to hear you were able to get GDM working as you want.

Note comment #25 of the bug I pointed you to before.  This comment
has a patch that makes timed login work for more displays than
just the first login and adds a new configuration option
TimedLoginFirstDisplay.

   http://bugzilla.gnome.org/show_bug.cgi?id=336174

It might be cool to update this patch so there is also an
AutomaticLoginFirstDisplay, and then GDM users could configure
whether they want timed/autologin to work on all displays just
by editing the GDM configuration rather than having to hack
the code.

So if you'ld be interested in reworking the patch a bit to make
it work for both autologin and timedlogin via configuration
options, then we could get this patch upstream.  Note the GDM 2.16
and 2.19 code is quite a bit different so the patch will likely
require a bit of rework to get working in GDM 2.19.
