I can confirm this bug with driver version 2:2.7.0-1ubuntu1~xup~1

One additional piece of information relating to this bug is that dual-screen works if I stack the monitors on top of each other when setting their relative positions.

For example, see this screenshot:

For some reason, this way of positioning the monitors does not ask to set a virtual resolution in my xorg.conf, and therefore it works.

When I set the positions of the monitors as in the following screenshot:

Then it asks to change the virtual resolution, tells me to restart X, and upon restarting it crashes ( http://dl.getdropbox.com/u/256410/IMG_0479.JPG )
