[LightDM] Trying to disable shutdown, reboot and hibernate from the loginscreen in lightdm

[Klaus Merkel]

Hi,

I'm in the process of building a kiosk system and have to lock it down. 
Now I need to disable or remove entirely the option to reboot, shutdown 
and send the system into hibernation. I'm running xbunutu 16.04.

Is this possible?

Best regards

Klaus Merkel
