Ubuntu
lightdm package

On 15.10 updated lightdm and unity-greeter stops working?

Asked by Knickers Brown

I upgraded lightdm from 1.16.6-0ubuntu1 to 1.16.7-0ubuntu1

After that unity-greeter stopped working and it switched to lightdm-gdm-greeter

Others report similar issues
http://askubuntu.com/questions/720321/15-10-lightdm-broken-gdm-works

I did not see the lightdm .Xauthority file missing.

$ sudo file /var/lib/lightdm/.Xauthority
/var/lib/lightdm/.Xauthority: X11 Xauthority data

How do I reconfigure to get back to unity-greeter?

Thank you

I installed 15.10 desktop in VM without patching at all and:

$ find /etc/lightdm/ -ls
131343 4 drwxr-xr-x 2 root root 4096 Oct 21 12:03 /etc/lightdm/
132967 4 -rw-r--r-- 1 root root 452 Oct 13 19:23 /etc/lightdm/users.conf

Nothing more.

On the afflicted system:

$ find /etc/lightdm -ls
3223352531 0 drwxr-xr-x 3 root root 87 Feb 7 12:20 /etc/lightdm

What causes /etc/lightdm/lightdm-gtk-greeter.conf.d/01_ubuntu.conf to be added?

dpkg.log on afflicted system shows lightdm-gtk-greeter was installed along with desktop-base.

I must confess that I put on the server version to get RAID correct and then added ubuntu-desktop package to convert to desktop but what choice did I have when the installer for desktop cannot install md RAID?
