It seems clear that at least analog hardware users who require panning
and want or need to stick to FOSS solutions need to stick to out of
support Xorg versions and/or out of support drivers, and/or ancient
gfxchip technology (e.g.  MGA), and/or cheap (and usually slow) hardware
(e.g. #  XGI Technology Inc. (eXtreme Graphics Innovation) Z7/Z9 (XG20
core), a slug at 24 bit, tolerable at 16 bit as long as not extending
the desktop virtually as panning was made to do). It looks like users of
supported FOSS software versions and modern competent gfxchips are out
of options other than acquiring (digital?) displays big enough, or
acquiring additional (digital?) video ports and (digital?) displays, to
cover their otherwise virtual needs.

Title:
  Panning in a virtual monitor is not possible after upgrade to Ubuntu

Status in “xorg-server” source package in Precise:

Bug description:
  When I go  for a virtual monitor by issuing command "xrandr --output
  LVDS1 --fb 1600x1200 --panning 1600x1200" on a monitor working at
  resolution 1024x768 (as I did before upgrading from Ubuntu 11.04 to
  Ubuntu 11.10), the WM bars on top and left side of the screen (in
  Unity) look like extending to the new area, but I cannot move the
  pointer to the new extra area and so I cannot pan. As far as I
  understood by reading around, this *could* be a bug in package "xorg-
  server" rather than in "xrandr" and *could* be related to the
  boundaries set for cursor position.
