Installing lightdm-gtk-greeter works, but I also found that the problem was that
unity-greeter wasn’t installed. I think the problem was that unity-greeter was
being called by the /etc/lightdm/lightdm.conf file but since it wasn’t
installed, it was just stalling.
Anyway, by doing a: sudo apt-get install unity-greeter
it fixed the situation and the machine boots. I also have the
lightdm-gtk-greeter installed, but it isn’t being used.
I am not sure why the unity-greeter wasn’t installed. My upgrade failed and I
had to restart it, but for some reason, starting the upgrade over didn’t solve
the problem. I wonder if maybe the upgrade installer didn’t like my hardware or
To check to see if your unity-greeter is installed, run the following command:
dpkg --get-selections | grep unity-greeter
