This is a real bug. It affects me in Lucid 10.04 LTS. It did not affect me in 8.04 LTS.
Some Radeon 7000 VE cards have two VGA connectors and some have one VGA and one DVI connector. The current code assumes tow VGA.
A fix has been checked in upstream: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/475145 http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=37b348059b1c15d7b381cd3df3db52bd9ee6613e This fix assumes one VGA and one DVI. Being wrong is less serious in the version.
