It seems you are right that the EDID is not always detected. In XorgLog.txt the information is there, but in XorgLogOld.txt it isn't. According to the logs you have an DELL E1909WDD connected via DisplayPort. Is that correct? Does the problem go away if you connect the monitor by other means (VGA, DVI, HDMI, etc.)? I think I have seen some updates to the EDID fetching code in the kernel lately. Could you try the 2.6.31-rc5 kernel from https://launchpad.net/~xorg-edgers/+archive/ppa (see also https://wiki.ubuntu.com/KernelTeam/MainlineBuilds) and see if the problem is still present there?
