I can confirm this behavior running on an Aspire One (Intel Corporation Mobile 945GME Express Integrated Graphics Controller) with xserver-xorg-video-intel 2:2.9.0-1ubuntu1 and compiz 1:0.8.3+git20091005-0ubuntu5.
As mentioned above, disabling compiz allows me to get into the screen configuration dialog, though the "detect monitors" button doesn't seem to work after this.
