I posted the following to bug #132716. However, "mek" referenced me to this bug as well. It appears that this bug could be more closely related to my issue.
I'm experiencing problems with dual-head setup and xrandr 1.2 on a recent upgrade to Ubuntu 7.10 on my Dell Latitude D810 laptop with docking station. Previously this worked 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 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 while the VGA-0 monitor displays "1: Analog Input Cannot Display This Video Mode". The "working" monitor shifts 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)? The log file from this session is attached. I can provide my xorg.conf upon request.
