Public bug reported:
Binary package hint: xorg
Recently upgraded from Lucid->Maverick->Natty.
I have only one monitor attached, but Natty thinks there are two.
xrandr reports both LVDS1 and VGA1 as connected. LVDS1 is the entry
that is incorrect. If I boot with the Maverick kernel instead of the
Natty kernel, xrandr correctly reports only VGA1 attached.
The Monitor Preferences tool also shows two displays, "Dell 17"" and
"Laptop". The "Laptop" is incorrect; this machine is not a laptop, and
only supports a single monitor.
