unable set GDM as greeter from Ubuntu 14.04 Live Custom

Asked by Davide Marchi

Hi friends,
I'm building a custom live Ubuntu (14.04) Gnome 3.12.2 based,
**Only** if I create a new user, set password and add him to sudo group,
setting by dpkg-reconfigure, GDM ad default greeter, obtain a black screen and going to the first console appear "authentication failure" message.

otherwise,
using dpkg-reconfigure and select the Lightdm as default greeter all work fine: the greeter show the login screen and the user is able to authenticate.

For build the iso I'm using the Ubuntu directive: https://help.ubuntu.com/community/LiveCDCustomization

Why this behaviour?

many thanks!

Why not stick to LightDM?

Sounds like a misconfiguration of your customisation.

I'm building a Ubuntu 14.04 GNOME based live. So I would like to set GDM.
I've try to purge the GDM package, but nothing.

thanks for your help!
