** Description changed:
In Lubuntu 13.04, I have an unusual display configuration: three
monitors arranged horizontally and a fourth centred above them. This
worked fine in 12.04; after upgrading, the middle display is not working
correctly.
xrandr --output DVI-1 --mode 1920x1080 --rate 60 \
--output HDMI-0 --mode 1680x1050 --rate 60 --right-of DVI-1 \
--output DVI-0 --mode 1280x1024 --rate 60 --left-of DVI-1 \
--output DisplayPort-0 --mode 1280x1024 --rate 60 --above DVI-1
Despite what xrandr claims, and no matter what I tell it, the middle
display (DVI-1) remains at 1280x1024 and displays windows from the
region 1280x1024+0+0, i.e. the region above the leftmost display (DVI-0)
that shouldn't be displayed. Windows in the region 1920x1080+1280+1024,
i.e. the region DVI-1 actually occupies, are not shown anywhere. The
other screens display correctly. (This can only be seen by dragging a
window partway off of the topmost or leftmost screen into this region,
since the mouse does move correctly and won't enter this region.)
Additionally, if xrandr is used to turn DVI-1 off, it will not be able
to turn it back on again. Like the region issue, it will claim the
display is on when it is not.
Additionally, the mouse cursor appears about twice as large as normal.
It does, however, move across the screens correctly.

- All of these things were working correctly on the same machine in 12.04.
- I hadn't tried 12.10.
