Bug#771653: systemd 217 breaks X11 (not more kdm and loggin and using startx gives me no mouse)

Hey,

I tried this morning on a vm (with multiple dms installed: lightdm, xdm, 
gdm and kdm) and when choosing kdm as the alternative to choose in the 
postinst and checking the status, all seems fine:
- all other units are disabled,
- display-manager.service is masked (as the default dm is an init script)
- generated kdm.service is chosen

Do you mind showing the output (as root) of:
systemctl status kdm.service
systemctl status display-manger.service

Thanks!
