Introduction

For me and many others the fdi files are just not familiar so I thought we need some help to configure the Lenovo X61 Tablet PC! The guide here will be written for Ubuntu Jaunty 9.04 and later versions supporting HAL and fdi configuration files.

Stylus

It works out of the box, you should know that every changes from https://help.ubuntu.com/community/Wacom can be applied to the fdi file as in xorg.conf for older versions of Ubuntu. but there is no need normally.

Eraser

Not configured by default but is easy to configure in the next step.

Touch

Works out of the box, just needs calibration .

Reassigning and calibrating

Using wacomcpl is straight forward you open an terminal and run it as normal user or by sudo .

Helping wacomcpl

The hal assigns names to wacom devices in a way that the recent wacomcpl from jaunty the they it was released was 8.2.2 cant find them , you need to rename then on every boot. Do the following steps to make to make sure it is done on every boot . open a terminal and type : 

sudo gedit /etc/init.d/wacomtohal

and paste this code in: 

## find any wacom devices
for udi in `hal-find-by-property --key input.x11_driver --string wacom`
do
type=`hal-get-property --udi $udi --key input.x11_options.Type`
## rewrite the names that the Xserver will use
hal-set-property --udi $udi --key info.product --string $type
done

then run : 

sudo chmod +x /etc/init.d/wacomtohal
sudo update-rc.d wacomtohal defaults 27

now reboot and launch wacomcpl

Making Wacomcpl Settings Restore on Reboot

If you lose your touch calibration after reboot:

In terminal: 

sudo gedit ~/.xinitrc

Find the line that says: 

. /etc/X11/xinit/xinitrc

and change it to 

#. /etc/X11/xinit/xinitrc

Save and exit.

Go to System>Preferences>Startup Applications and create a new entry named whatever you want.

The command should be: 

sh /home/yourusername/.xinitrc

Your wacomcpl settings will now restore on reboot

Making Wacomcpl Settings Restore on Resume

If you lose your configuration after resume from standby or hibernate follow these instructions to create a binary daemon that will restore your settings:

In Terminal 

gedit monitor_wacom.c

Enter the following code: 

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <assert.h>

char method_line[1024];

int main(int argc, char **argv) {

        if (argc != 2) {
                printf("Usage: %s [script to run]\n", argv[0]);
                return 1;
        }

        FILE* in = popen("dbus-monitor --session type='signal',interface='org.gnome.ScreenSaver',member='ActiveChanged'", "r");

        while (1) {
                char buf[1024];
                assert(fgets(buf, 1023, in));
                
                if (buf[0] == 's' /* early exit optimization */ && strstr(buf, "ActiveChanged") != NULL) {
                        assert(fgets(buf, 1023, in));
                        if (strstr(buf, "false") != NULL) {
                                /* resumed */
                                assert(system(argv[1]) == 0);
                        } else {
                                /* put to sleep */
                        }
                } 
        }
}

Save and Close

In Terminal: 

gcc -O2 monitor_wacom.c -o .monitor_wacom

Go to System>Preferences>Startup Applications and create a new entry named whatever you want.

Its command should be: 

/home/yourusername/.monitor_wacom /home/yourusername/.xinitrc

Reboot.

Middle Button Scrolling

Create a new file called /etc/hal/fdi/policy/mouse-wheel.fdi typing: 

sudo gedit /etc/hal/fdi/policy/mouse-wheel.fdi

And fill it with this code: 

<?xml version="1.0" encoding="UTF-8"?> 

<match key="info.product" string="TPPS/2 IBM TrackPoint">
 <merge key="input.x11_options.EmulateWheel" type="string">true</merge>
 <merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>
 <merge key="input.x11_options.XAxisMapping" type="string">6 7</merge>
 <merge key="input.x11_options.YAxisMapping" type="string">4 5</merge>
 <merge key="input.x11_options.ZAxsisMapping" type="string">4 5</merge>
 <merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
</match>

Reboot

More

Feel free to add more stuff here as I don't see any need now, but an autorotation script for the screen would be nice, I will add one as I find one.
