[Daniel Manrique <daniel.manrique@xxxxxxxxxxxxx>]

Tested with Oneiric image from July 5th on the Dell 2110. Upon connecting external display, the external goes black as in picture 2. The internal display gets a "ghost" copy of the top panel, about 2/3 of the way down the screen. from that point up until the actual top panel, everything is black. From the ghost panel down to the bottom 1/3 of the screen, residual images of the apps that are there can be seen. However, apps themselves are not visible in the top part, and the visible parts in the bottom of the screen don't refresh or update. The cursor pointer is "alive", I can move it and it even responds to what's "underneath" (i.e. changes shape to signify a draggable border, a text area, and so forth) but even if I'm manipulating stuff, I can't see anything as the screen is not getting redrawn.

To be fair, I haven't tested Oneiric on a system that used to work fine in Natty, but still, the faulty behavior seems to still be there in a similar way.
