what a7x described here:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/227520/comments/17
is pretty much my experience too.

I just tried jaunty alpha3 and it seems to bring some improvements. The following command
xrandr --output VGA-0 --below LVDS --mode 1024x768
now achieves to set the external monitor resolution correctly. Unfortunately, if I run afterwards just:
xrandr
the external monitor reverts to cloned mode and needs a VT switch to go back to the correct configuration. Similarly as in Intrepid.

I repeat my `lspci -vvnn` here:
