Comment 14 for bug 377598

I burned the Karmic Koala Alpha 2 64-bit desktop image to a CD-RW, booted off it, and tried reproducing the problem using the steps in comment 0. The exact same behaviour described there is still present.

It has occurred to me that the 'safe' resolution of 1024x768 may merely be the largest of the resolution my two displays have in common, rather than a maximum pixel-count limit or something.

I discovered a presumably unrelated problem that if I boot Karmic while the external monitor is connected, X eventually freezes and the computer needs to be hard-booted. Unfortunately, because I was booting off a CD, rebooting erased all the log files and I do not have sufficient information to file a bug.

As requested, I have attached the Xorg.0.log file that was created while I was reproducing the bug.
