I'm running native 1400x1050 on main display, when I connect to external display
it is set to 800x600 and both displays are blank.
If I manually set main display to 1152x864 then both displays work.

I believe this is expected with said hardware. Maybe Ubuntu should guarantee
that combined resolution will not exceed hardware limits?
