General

I recently installed Ubuntu 6.10 on the Panasonic Toughbook CF-18 Tablet PC (model CF-18FDHZBVE) that I had previously installed Ubuntu 5.10 on (you can find that writeup here). This model comes in two versions - one with a touchscreen (i.e. you can use your finger) and one with an active digitizer (i.e. you need the pen). The digitizer model is the one in this article.

And here is the proof of the pudding - using the digitizer to sketch in GIMP:

Installation

Installation was rather smooth as I had the external USB DVD/CD drive for the machine (the CF-VDRRT3). A standard install of Ubuntu 6.10 was put on the machine.

Graphic Card

The graphic card is integrated into the Intel 855GM chipset. This is supported by the i915/i810 drivers out of the box. Apparently (according the the X server logs) XRandR is now supported out of the box with this driver (which would allow screen rotation), however I have not as yet got this configured.

Note that this configuration is for the Active Digitizer version of this model. For the Touchscreen version, you could try the commercial X server from Xi Graphics here.

Xorg

The essential parts in /etc/X11/xorg.conf are as follows. The only change I made was to change the wacom device from /dev/wacom to /dev/ttyS0:

   Section "InputDevice"
       Identifier  "stylus"
       Driver      "wacom"
       Option      "Type" "stylus"
       Option      "Device" "/dev/ttyS0"
       Option      "ForceDevice" "ISDV4"
   EndSection

   Section "ServerLayout"
       ...
       InputDevice "stylus" "SendCoreEvents"
       ...
   EndSection

Pen - Wacom Active Digitizer

The pen digitizer is a serial Wacom digitizer. This was configured at the /dev/ttyS0 serial port on my machine and autoconfigured successfully. I found this by looking through the dmesg output as the machine has no other serial ports. This can be tested by installing the wacom-tools package, and running the following (as root):

wacdump -f c100 /dev/ttyS0

If everything is working, you should get position and button press status reported by this tool.
