xrandr: screen cannot be larger than 1680x1680 (desired size 3360x1050)


I have two ViewSonic monitors that can display 1680x1050 each
I want to use xrandr to extend my desktop to 3360x1050.

It has an intel dual core 2 and integrated intel GMA x4500 grpahics.
and I am running Ubuntu 9.04 (Jaunty)

I know the extended view is working under Vista.

But linux is limiting me:
$ xrandr --output HDMI-2 --auto --right-of VGA
xrandr: screen cannot be larger than 1680x1680 (desired size 3360x1050)

I have tried editing the xorg.conf as the many forums suggest but I am getting nowhere.

Supporting info below

Add:

SubSection "Display"
Virtual 3360 1050
EndSubSection

Under Section "Screen"

That will make xrandr and any gui tool based on libxrandr work.
