LightDM won't load: Stopping startpar bridge for notification of upstart job start/stop

[Ads20000]

Installed the Ubuntu 14.04 "Trusty Tahr" daily image (21-Oct-2013 13:57) into Virtualbox 4.2.18 r88780 and it won't load LightDM, I switched to tty1 and I see the following message:

    Stopping startpar bridge for notification of upstart job start/stop

On several lines alternating between `[start]` and `[stop]` messages at the end. If I use `sudo lightdm restart` it just brings up a blank screen. I didn't have this specific problem when I was running the Saucy development branch.

When I try to use `sudo lightdm restart` I get the error:

    Failed to use bus name org.freedesktop.DisplayManager, do you have appropriate permissions?

and I get a blank screen again.

I'm having the same issue on a clean install of Ubuntu server 13.10 :

these startpar bridge messages have nothing to do with a lightdm failure to start.

However I don't get the problem in the description when I use GDM by default (or I use `gdm start`).

[Francesco Randi (francesco-randi)]

Same problem since yesterday:
I have an integrated (intel) and a discrete (radeon) graphic card, and it seems that the update "broke" just the integrated one. I'm running fine on the radeon one now..

Below an extract of /var/log/dpkg.log, regarding the updated packages that could be related to the problem:

2014-02-23 16:36:58 upgrade xserver-common:all 2:1.14.3-3ubuntu2 2:1.14.5-1ubuntu2~saucy1
2014-02-23 16:36:59 upgrade xserver-xephyr:amd64 2:1.14.3-3ubuntu2 2:1.14.5-1ubuntu2~saucy1
