Public bug reported:

Hello

I'm using a EliteBook Folio 9470 (Intel QM77 chipset with Intel HD
Graphics 4000) and initially installed 13.04 beta2.

I used to work with 2 external monitors plugged in (one via VGA and the
other one using a HP-DisplayPort-To-HDMI-adapter).

Everything worked properly (both displays using 1920x1080 resolution, laptop 
lid closed); I used this config the last time on 2013-04-26. Some package 
upgrades were performed in the meantime (I guess including the final release) 
and this morning when trying to boot in this configuration again, the second 
external monitor (via display port) is not recognized anymore.
The first external monitor (VGA) is still recognized and working as expected.

xrandr output:

(shows only laptop & VGA display)

Since my old configuration with both displays is still in 
~/.config/monitors.xml, I assume there was a port named 'HDMI3' that is not 
there anymore:

Since it worked on 2013-04-25 I assume some of the packages updated on
the next day might be the culprits:

Maybe a change in lightdm (even though I downgraded to the last version
and still not working) or in xdiagnose?

Maybe it was even some package update performed on the 2013-04-25 (udev
changes?)
