[LightDM] how to exit display manager

[Gabriele Bulfon]

But looking at the lightdm.c code, I see two callbacks waiting for signals, handling daemon exit.
Isn't it possible to send these signals from the greeter to its parent (lightdm daemon)?
Or, how may I patch in a good manner the lightdm-gobject code to provide such a function?

No, the greeter does not have the permissions to shut down the lightdm service. If you need to do this you should use existing methods to shut down the service and make the "lightdm" user account able to access this.

(in the console)

Hi,
I'm customizing the power menu, adding "Exit Display Manager..." to get back
to text console.
I tried issuing a sigsend SIGQUIT to the parent pid of the greeter, but
doesn't work.
What is a correct way to tell lightdm to quit?
BTW I could patch lightdm to support Solaris RBAC and allow for shutdown and
reboot through HAL
dbus. :)
Thanks!
Gabriele
