Public bug reported:

Binary package hint: xorg

Xrandr's panning feature does not work correctly in Karmic. The mouse
pointer keeps "losing its place" while moving outside the boundaries of
the viewport. Because of this, certain areas of the display cannot be
reached because the mouse position has been offset (i.e. the mouse
pointer is displayed in a place different from where it should be).

The command I used to enable panning is:
xrandr  --fb  4096x1600  --output  LVDS1  --mode 1280x800 --panning 4096x1600

Changing the resolutions does not fix the problem.

However, disabling kernel mode setting by adding the option "nomodeset" to the kernel command line in GRUB fixes this problem. I also have to change LVDS1 to LVDS:
xrandr  --fb  4096x1600  --output  LVDS  --mode 1280x800 --panning 4096x1600

I would like to have a panning display in Ubuntu 9.10 without resorting
to nomodeset.
