10.4 Wacom Multi-monitor mapping

Asked by Talia

I'm running multiple monitors and I cannot figure out how to get my Intuos 3 6x8 Wacom tablet to map to only one monitor, at a proper aspect ratio. Right now it's stretched over both monitors, and this makes it basically useless for drawing, because of the non-square aspect ratio. I'd like to know how to change the mapping.
In addition, the windows drivers have a feature letting you switch the tablet mapping between two monitors by pressing one of the tablet buttons. If anyone can suggest a method of doing this (possible a shell script?) I would be grateful.
Thank you!

You'll need to edit the configuration with root privileges. Open a terminal (Applications > Accessories > Terminal) and type:
gksudo gedit /usr/lib/X11/xorg.conf.d/10-wacom.conf
(That should all be on one line, and watch out for the capital X in X11)

Before the "EndSection" line of the section which starts with:
    Identifier "Wacom class"
add the following options:
Option "KeepShape" "on"
Option "ScreenNo" "0"
Replace the 0 with a 1 if you need to constrain the cursor to the other monitor.

Be careful to type correctly. Errors can prevent your computer from starting properly—I learnt this the hard way.
Save the file and reboot to activate the changes.

There are plenty of other options that can be added. In the terminal type:
man wacom
to read about them all. For example I have
Option "TPCButton" "on"
Option "PressCurve" "25,0,100,100"
so pen-button presses aren't activated until I touch the tablet, and it's easier to draw soft lines.

I haven't figured out how to get the tablet buttons to work though yet.
mentions a bug and a solution, but I only found it the other day so I haven't tried it.

I also found these useful to get me started in figuring this out:

And xsetwacom can probably used to change between the monitors.

Can you help with this problem?
