Binary package hint: xserver-xorg-driver-ati

I'm experiencing problems with dual-head setup and xrandr 1.2 following a recent upgrade to Ubuntu 7.10 (Gutsy) from Ubuntu 7.04 (Feisty) on my Dell Latitude D810 laptop with docking station. This worked on Feisty with the ati driver and it still functions when I change over to the "fglrx" driver (which rules out bad hardware).

I have a striped down configuration xorg.conf (see below) with two identical Dell FP1905 monitors connected through a docking station, one via VGA-0 and the other via DVI-0. On startup the DVI-0 monitor functions as expected and the LVDS monitor initializes but displays nonsense (some wierd color patterns). I then issue the following command to disable the LVDS:

xrandr --output LVDS --off

At this point, I can then activate the VGA-0 monitor with this command:

xrandr --output VGA-0 --auto

However, VGA-0 then displays "1: Analog Input Cannot Display This Video Mode". But, the working screen will "shift" from DVI-0 to VGA-0 when I issue the following command:

xrandr --output DVI-0 --crtc 0 --output VGA-0 --crtc 1

At this point, my desktop is properly displayed on VGA-0 while DVI-0 displays "2: Digital Input Cannot Display This Video Mode". Is it possible that this bug is related to "crtc 0" on the ATI x600 (M24)?

I have tried turning the "LVDSBiosNativeMode" option to "false", turning the "DRI" option to "off" and playing around with the "Virtual" option. Unfortunately, nothing has had a positive impact. The log file from my current session is attached and my xorg.conf is included below.
