Package: lightdm
Version: 1.2.2-3
Severity: serious
Justification: Renders package unusable

Dear Debian folks,

installing `lightdm` it runs, but the greeter does not show up. :/ Only
a blinking cursor in the top left corner on VT 7.

Somehow the X server is just closed

        $ sudo more /var/log/Xorg.0.log
        [  1126.596] (II) UnloadModule: "evdev"
        [  1126.606] Server terminated successfully (0). Closing log file.

and LightDM does not find a X server.

        $ sudo service lightdm start
        Starting Light Display Manager: lightdm already running.
        $ sudo more /var/log/lightdm/lightdm.log

There is also *no* `/var/log/lightdm/x-0.log`.

Any help would be appreciated.
