Public bug reported:

Binary package hint: xorg

This week my laptop stopped detecting the right resolution on an
external projector.

Wednesday Nov 3d I was still able to use the full resolution (1280×1024)
of the Epson EB-S6 projector. Today the max resolution is 1360×768,
which is displayed distorted. The only other resolution available is
1024×768.

Between these two sessions I did not do anything with my computer
besides normal browsing and OO.o work. The log of updates is attached.

Ubuntu 10.10 fully updated
HP NX7400
Let me add how grateful I am when this tricky area "just works", which it did with Maverick, and how distressed when 25+ Windows users only see Ubuntu in a crammed, pixelized frame. Thank you for your work.
