Bryce,

Yes I can confirm that this happens when connecting the laptop directly to the external monitor (not using the dualhead2go).

Now, what I did is (all from Classic Desktop no effects - and from gnome-display-settings:

1. Connect external monitor to VGA
2. Enable mirror screens: WORKED
3. Disable mirror screens and Enable external monitor at 1920x1080: WORKED
4. Disable LVDS and leave VGA as sole monitor: FAILED (You can see what happens in the video: [1])

Now, if I do step 4 with xrandr (disable LVDS with xrandr), it works perfectly.

Furthermore, if I save the configuration (LVDS disabled, VGA1 Enabled) and reboot the computer, then LVDS is off by default and VGA1 should be displaying the image, however, the same occurs as with video [1].

Finally, if I do the steps above but place LVDS *under* the external monitor (using gnome-display-settings), the same as video [1] occurs.

Hope this helps. Please let me know if you need any further info.
