Installing Ubuntu 6.10 on a ThinkPad X41 Tablet

This document describes the process of (installing and?) configuring Ubuntu Edgy Eft (final release expected October 2006) on a Lenovo ThinkPad X41 Tablet. With whatever relevance it may have, the particular model number used in testing was an 1869CSU. Keep in mind that at this document's inception 6.10 is a development version of the Ubuntu Linux OS.

Pre-Installation Notes

Tablet Screen Rotation (updated i810 drivers)

This edition of Ubuntu (Edgy) has XRandR enabled i810 drivers, which allow you to rotate your screen orientation on the fly. The command xrandr -o [orientation] will rotate your screen to your liking. For more information about the xrandr command, refer to the man file (man xrandr).

Wireless Support

Wireless seems to be supported flawlessly in terms of drivers, though I'm not sure how well the built-in Network Manager works. I use the iwconfig command to manage my wireless, as I have a need to create pseudo-"profiles", and in this document I will describe this alternative process.

Fingerprint Reader Support

Honestly, I care very little about the fingerprint functionality. Its only real use seems to be for gksu-type logins while the tablet is swiveled down, which doesn't occur often in my setup. If someone wants to explore/expound, please do, but I won't include any details about the fingerprint reader in this document.

Terminology Used

For those of you new to Linux, I'll try to detail a few terms I use with little explanation: Xorg configuration -- the display configuration file, residing in /etc/X11/xorg.conf Execute a command -- press Alt-F2, then type gnome-terminal into the prompt and press enter -- this is a terminal into which you input said commands

Installation Notes

The installation process didn't require anything exceptional. Feel free to fill in the blanks if it could be useful.

Post-Installation Notes

Configuring Xorg

TrackPoint

Like in all ThinkPad Xorg configurations, add the following under the "Configured Mouse" device to enable TrackPoint scrolling:

Option "EmulateWheel" "true" Option "EmulateWheelButton" "2"

Wacom Stylus

First install the wacom drivers with the following command:

sudo apt-get install wacom-kernel-source xserver-xorg-input-wacom wacom-tools

After doing this, I strongly suggest that you reboot your computer; however, if you're one of those people whose uptime is on the order of four years, I'm sure you'll figure out an alternative that I won't be describing here.

Next step is to check to see if /dev/wacom exists. A 'ls -al /dev | grep wacom' should do the trick quite nicely. If it does exist, add the following to your Xorg configuration.

Section "InputDevice"
 Driver        "wacom"
 Identifier    "stylus"
 Option        "Device"        "/dev/wacom"
 Option        "Type"          "stylus"
 Option        "ForceDevice"   "ISDV4"
EndSection

Section "InputDevice"
 Driver        "wacom"
 Identifier    "eraser"
 Option        "Device"        "/dev/wacom"
 Option        "Type"          "eraser"
 Option        "ForceDevice"   "ISDV4"
EndSection

Section "InputDevice"
 Driver        "wacom"
 Identifier    "cursor"
 Option        "Device"        "/dev/wacom"
 Option        "Type"          "cursor"
 Option        "ForceDevice"   "ISDV4"
EndSection

Some people seem to have slightly different configurations (potentially due to model differences). At any rate, if you're looking to find what serial device your stylus is, a simple 'dmesg | grep ttyS' should do the trick. Be sure to append to this article if the procedure varies from model to model.
