FreeBSD on a Fujitsu Stylistic Tablet PC

[Eric Millbrandt]

Here are the results of my efforts to install freebsd on a tablet pc.  
My tablet is a Fujitsu Stylistic ST5030.  It has a 12" XGA screen with a 
Wacom Penabled screen with an active digitizer.  The tablet has no 
keyboard or cdrom drive so the initial installation can be tricky.  
FreeBSD installation is very well documented so I will just highlight 
the snafus.

Installation:

You will need a USB keyboard, or the Fujitsu IR keyboard, and external 
cdrom drive.  If you are clever you could install over the Ethernet port 
or wireless card instead of using the external drive.

Xorg configuration:

The Wacom Penabled screen is connected to the system via /dev/sio1 at 
irq 4 over port 0x220, so you will need to modify your device.hints file.

To create you xorg.conf Xorg -configure will do most of the heavy 
lifting.  The wacom drivers included in Xorg do not drive the mouse 
successfully and are not even included in Xorg 7.2.  Working drivers can 
be found from http://linuxwacom.sourceforge.net/.  The already built 
driver can be copied from /prebuilt/wacom_drv.so to 
/usr/local/lib/xorg/modules/input/.  You will then need to add 
additional sections your xorg.conf.

These need to be placed in your ServerLayout.

    InputDevice    "cursor" "SendCoreEvents"
    InputDevice    "stylus" "SendCoreEvents"

These sections also need to be added.

Section "InputDevice"
    Driver  "wacom"
    Identifier      "cursor"
    Option        "Device" "/dev/cuad1"
    Option        "Type" "cursor"
    Option        "ForceDevice" "ISDV4"
    Option        "Mode" "Absolute"
    Option        "TPCButton" "on"
    Option        "KeepShape" "1"
    Option        "ScreenNo" "0"
EndSection

Section "InputDevice"
    Driver  "wacom"
    Identifier      "stylus"
    Option        "Device" "/dev/cuad1"
    Option        "Type" "stylus"
    Option        "Button1" "1"
    Option        "Button2" "2"
    Option        "Button3" "3"
    Option        "ScreenNo" "0"
EndSection

You can get a detail description of these options from the wacom man 
page included in tarball.  Now you should be able to run 'startx' and 
use the wacom pen as your mouse. 

Additional configuration:

You are probably going to want to use your tablet as it was intended, 
without a keyboard. 
Once Xorg has started you can use a virtual keyboard to do your typing.  
xvkbd works well.  It can be found under /usr/ports/x11/xvkbd.  But what 
to do before Xorg starts?  Edit /etc/ttys and change 'no' to 'yes' in 
this line.
ttyv4    "/usr/X11R6/bin/xdm -nodaemon"    xterm    off  secure
Now xdm will handle logging into the system and starting Xorg.  You will 
probably want xvkbd to be started so that you can logon using only your 
pen.  Edit /usr/local/lib/X11/xdm/Xsetup_0 and add xvkbd to the list of 
programs to start.  You can leave xvkbd running as user root, but I find 
that not being able to kill it annoying.  Edit 
/usr/local/lib/X11/xdm/GiveConsole and add 'killall -9 xvkbd'.

Optional features:

I run a dual boot system with windowsXP.  The default FreeBSD bootloader 
lets you select which os to boot with F-keys.  The only keys you will 
find on are arrow keys, enter, and some other misc. stuff.  The GRUB 
bootloader, /usr/ports/sysutils/grub, supports using these keys to 
select your os.

One of the nice features found in windows is screen rotation.  Xorg can 
also handle screen rotation using xrandr.  What does not support 
rotation, without some help, is your pen.  You need to build xsetwacom, 
found in the linuxwacom tarball you downloaded, to rotate the pen on the 
fly.  I wrote a small script to run both xrandr and xsetwacom.

Another feature of the tablet that you might want to use is the external 
monitor port.  Details about how to do this are found in the i810 man 
page.  Unfortunately there is a bug in the Xorg i810 driver and the 
915GM video chip which makes setting up dual monitors tricky.  I cannot 
explain the specific details about this issue, but I can explain the 
workaround.  915resolution, /usr/ports/sysutils/915resolution, needs to 
be run before Xorg starts.  Now you can use the external monitor port. 

What does not work:

I have yet to find any utility to run the keyboard buttons on the 
tablet.  acpi_fujitsu.ko does not seem to support the Stylistic line of 
tablets.
