Comment 7 for bug 654515

I am also seeing this on a dell destop. This worked perfectly in jaunty and lucid but when i upgraded to Meerkat it stopped. When the monitors are positioned side by side the right screen is black and the cursor will move only a few pixels onto it. I changed the resolution from 1600x1200 all the way down to 640x480 and got the same results. If I tell it the screens are one over the other they both display properly.
