/etc/gdm.conf and the "Actions" SystemMenu.
I'm running gdm 188.8.131.52-1 and I want to allow normal users
to reboot or shutdown the machine from the GDM greeter.
/etc/gdm.conf contains the following:
# The Actions menu (formerly system menu) is shown in the greeter, this is the
# menu that contains reboot, shutdown, suspend, config and chooser. None of
# these is available if this is off. They can be turned off individually
# The Actions in the Actions menu require the root password
But it doesn't say *how* to turn the menu items off individually.
I'd to allow only shutdown and reboot without the root password.
