A kernel update? >From the old Xorg log with the working EDID you should at least be able to see what kernel you were running at the time, so that's something that you might try. (Whether the kernel is relevant depends on whether you are using kernel modesetting---that is, loading the i915 kernel module with modeset=1. If you are using KMS, then yes, the kernel is very relevant. If not, then it likely won't have any effect here.) Beyond replicating the originally working software environment as well as possible, you can explore whether there's some other issue that could have affected things. For example, is it possible to switch cables from a working to a non-working monitor? -Carl
