[Bug 491940] Re: Patch for LTSP clients to properly reboot/shutdown

[Alkis Georgopoulos]

Reopening in LTSP, as it seems we'll need to find another method in
order to get working shutdown/reboot menus, and I'm not sure if we have
enough time left to make it for Lucid.

Maybe the indicator-session applet could be patched instead, like fusa
was in previous releases, although patching gnome-session was much
better because it worked with the session dialog as well, and with
applications like iTalc that directly call dbus.

It'll be the first LTS release with that problem... if any fellow
teacher needs a patched gnome-session to avoid having to explain to the
students why the reboot/shutdown menus in Ubuntu are not working, he may
find one in the PPA for Greek schools:
