Sebastian,

With regards to my issue of my multi monitor setup  breaking and reverting back to low res mirror setup, would you say that is Xorg or gnome-session? I am not sure under what to log it and what info to provide, as the ONLY errors that I receive, when this happens, in my logs are:

I ran: "tail -f /var/log/*.log"  when i logged in and used the desktop until the setup broke and these were the only errors logged. 

Where do I go from here, this has been ongoing since the day 12.04 started development and I'm worried that this is an unknown bug that is not getting attended to. My original bug 921540 was marked as duplicate of this bug yet none of my errors point to gsd crashing.
