I mean that I was working in portrait mode, then, with X running,
rotated the display to landscape mode, and the displayed pixels did not
change, so that e.g. menus and applications were now sideways.
I then used xrandr on the system with the ATI card; I forget what I did
on the laptop with an nvidia card. The result was a loss of
acceleration. I did not edit xorg.conf at all.
Does rotating the screen work in Windows?
This sounds like something that isn't supported via the DVI/VGA cables or a problem with support in the proprietary drivers.
The drivers could probably do the rotations, they just never got the proper signal. Having "Xinerama" enabled for the AMD
drivers really restricts what options you have, but duasl monitors didn't work with AMD's driver any other way.
