Comment 6 for bug 161816

More tests, - After I selected different monitor, restarted X Server and put all the settings that worked back ( Generic LCD 1600x1050 , 4:3, same resolution), it stopped to work again.

Deleting xorg.conf completely seemingly resolved the "off-screen desktop" problem, but aspect ratio of everything became absolutely wrong, to a point of non-legibility (for me).

Manually edited modelines (see below) allowed me to get almost normal 1280x768@60 mode, and all the other ones now behave predictably, - 4:3 ones have aspect ratio problem, and 16:x have "off-screen" problem.

I'm yet to download Hardy CD.
