I'm very interested in this and have tried any number of incantations
to get a panning desktop... the above formula fails here.
The desktop grows but the panning just does not happen... mouse is
still locked into actual monitor size and just moves the screen very
slightly when bumped up against any border.
Some have said its due to bugs that I have lost track of but there are
several in different OS's reported where the panning is restricted.
Maybe I've got the command all wrong:
(wrapped for mail but was on 1 line)
xrandr --output DVI-I-1 --rate 60 --mode 1440x900 --fb 2048x1536 \
--panning 2048x1536
As I understand your statements here `--mode' should be your actual
monitors max resolution... right?

What I actually see is the screen grow but I cannot access the part
that is beyond the edge of my monitor... when I go there with the
mouse only a very slight shifting of screen happens... maybe something
like 1/8 inch.
For example: the `system tray' (or panel) in default kde desktop is
across the bottom. When I run the command above it is pushed down out
of site... attempting to pan to it with mouse does not work. I only
get the tiny screen shift reported above.

I guess you are able to get a panning desktop... and your mouse, when
moved to a monitor border, shifts the screen so you can get to the
virtual real estate?
Why does it fail here? Any ideas welcome.
