Hi,
I can make the external touchscreen work with this:
xrandr --output LVDS1 --right-of DVI1
which gives me 1920x1080 on DVI1 and 1920x1200 on the notebook.
Now the touchscreen moves the mouse relative to the entire
virtual screen (3840x1200). How can I restrict the touchscreen
inputdevice to the external monitor?
I believe it should work with xorg.conf (see below) entry but it
seems that xrandr ignores this.
I am running kubuntu 9.10 with backported KDE 4.4
X.Org X Server 1.6.4
root at notebook:/etc/X11# cat xorg.conf
