I downloaded Gutsy Gibbon Tribe 3 (Desktop) and tried to launch it live to check about this bug.
Well, the situation isn't changed so much. I can't still boot X due to this "No matching modes found" problem.

Anyway, in the original report for this bug, I said: "a sudo dpkg-reconfigure xserver-xorg, even accepting all default choices, solves the problem." Now, this is no more true, because an xserver-xorg reconfigure doens't help at all. You can check out attached Xorg.conf and Xorg.log after the reconfigure.

The only solution is to connect to the Internet and download the fglrx driver (a simple apt-get install xorg-driver-fglrx). After that, a dpkg-reconfigure xserver-xorg, accepting all default values (except regarding the resolution), solves to problemĀ¹.

My hardware isn't changed from the original report for this bug (a Dell Inspiron 6400 with an Ati Mobility Radeon X1400 and 1280x800 LCD panel).

[1] After installing fglrx, when I reconfigure xserver-xorg, I can't choose Monitor autodetection, otherwise screen goes black and system is no more usable - need to reboot)
