Public bug reported:

I just installed Xubuntu 11.10 Oneiric on my netbook, a MSI Wind U100.
On my previous OS (Jolicloud 1.0, derived from Ubuntu Jaunty), I used an applet relying on xrandr to expand the screen resolution when needed.
Indeed, my screen is 1024*600, and some programs and dialogs are higher than 600px. So when needed I used xrandr to resize it to 1024*768 with panning.

On Oneiric, however, this no longer works.
I can still run xrandr, and the display is resized correctly, but the area in which I can move the mouse stays the same 1024*600 box.

1) When using panning mode

I start panning mode with the following command :
xrandr --fb 1024x768 --output LVDS1 --mode 1024x600 --panning 1024x768 --scale 1x1

In that case, the display is resized (all windows become higher than the screen, etc).
However, I cannot pan to the bottom : my mouse cursor cannot go lower than the lower bound of my screen, so I can only pan by 1 or 2 pixels.

2) When using scale mode

I start scale mode with the following command :
xrandr --output LVDS1 --mode 1024x600 --scale 1.28x1.28 --fb 0x0 --panning 0x0

In that case, the display is resized so that a 1311x768 display fits on my screen.
However, I cannot move the cursor on the whole screen : it cannot go lower than the "virtual" 600px (actually 469 after resize), nor more to the right than the "virtual" 1024px (actually 800).


This basically makes xrandr unusable, which can be a real problem on such small screens.

Also, this bug isn't specific to Ubuntu : I found other bug reports elsewhere.

>From my research, it looks like it was introduced in libxrandr 1.3.1.
Also, this bug was apparently already reported for Ubuntu but on an incorrect package, and I don't know how to move it. 
See it declared as a compiz bug here : https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/866065 , but I'm not running Compiz on Xubuntu.

Feel free to ask more information about my system if you think it might
help.

Thanks.

Title:
  --scale and --panning options do not resize the mouse area accordingly
