> Bug description:
>   Occurs reliably on fast Sandy Bridge hardware with a fast GPU - GTX
>   485M, GTX 560M or GTX 580M.

>   Appears to be a race condition. LightDM attempts to start before

>   lightdm start" to /etc/rc.local to start the service.

>   ### This workaround is insufficient. Some users have reported that
>   their systems do not start after initial user setup. Deleting the
>   contents of /var/run/dbus/* resolves the issue in these cases. ###
