Introduction

This page covers the additional hardware setup required after installing Ubuntu 9.04 Jaunty to make the Thinkpad X61 Tablet Fully Functional. All directions are given in the HAL, fdi, and acpi thus avoiding the xorg.conf file completely.

What Works

Forward / Back Buttons, Audio Buttons, Brightness Fn Buttons, Radio Fn Button, Suspend Fn Button, Power Fn Button, Lock Fn Button, Hibernate Fn Button, Tablet L/R/U/D Buttons, Tablet Enter Button, Tablet Esc Button, Media Fn Buttons NumberLock Fn Button, Tablet Pen, Wireless Radio, Bluetooth Radio,

What Almost Works

Tablet Tools Button - causes lock or suspend, Tablet Touch – Requires Calibration,

What Does Not Work

Tablet Control-Alt-Delete Button, Tablet Rotate Button, Middle Mouse Button, ThinkVantage Button, Magnify Fn Button, Fingerprint Reader, Automatic Screen Rotation, ThinkVantage ActiveProtection,

Fixing Touch

Works out of the box, just needs some calibration.

Wacomcpl

The Wacom Tablet in the X61t is a serial Wacom tablet. It can be configured by using wacomcpl. Wacomcpl is part of the wacom-tools package and can be retrieved in apt: 

sudo apt-get install wacom-tools

After this wacomcpl can be run by typing: wacomcpl in Terminal.

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.
