Fujitsu Stylistic ST4110 Tablet PC

This guide is how to setup SuSE 9.2 Linux on a Fujitsu Stylistic ST4110 Tablet PC. This guide assumes you understand the basics of installing SuSE and know how to edit basic files. This guide should also be relevant for the ST4120 model.

Basic Installation Tips

Physical Installation

I used an external CD-ROM drive to install. The unit supports booting through USB, check the BIOS for booting from "Optical Drive". With a selective set of packages installation takes a little over an hour.

Partitioning

For this setup Windows XP was completely removed. Use any preferred partitioning scheme with the following notes.

• Recommended: All partitions should be EXT3.
• Do NOT use ReiserFS if you want to have ACPI S3 (Suspend to RAM) functionality later.
• Also set the SWAP partition to double the memory size (512MB swap for 256RAM, ~1GB swap for 512RAM).

Note: SuSE by default partitions with ReiserFS. To test or experiment with things such as ACPI, your system must endure crashes (lockups, kernel panics, etc.). Some tests caused ReiserFS corruption that I could NOT fix. I have not had this happen with EXT3.

Packages

Make sure to search the packages available and install the following:

• To use the Pen: linuxwacom
• LSB packages
• Compiler & Tool packages
• Onscreen X11 keyboard xvkbd
• Any kernel source or kernel development packages

Post Installation Updates

Run the YaST update as you normally would after installing SuSE. Obtain any update required for your hardware, especially any software for wireless devices you plan to use.

Tablet and Pen Setup

There are 2 files I am providing: my updated /etc/X11/XF86Config file with necessary changes and my original XF86Config file. They are included so you can see the differences. Zip file containing both files: xf86_fuj_su92.tar.gz.

Font Issue: If you do NOT want very large fonts. In XF86Config, comment out "DisplaySize" under "Monitor". By using the above config file you will no longer be able to use YaST without losing the above settings.

An additional link is required. As root:

# cd /usr/lib/TkXInput/
# ln -s libwacomxi.so.0.0.0 libwacomxi.so

To setup the serial port required for the Pen. As root:

# echo "/bin/setserial /dev/ttyS0 irq 4 port 0x220 autoconfig" >> /etc/init.d/boot.local

After the above changes are made, REBOOT. Once the X server starts, run the following (as user, not root):

# wacomcpl &

Virtual Onscreen Keyboard

To setup the virtual keyboard with KDM add the following 2 lines to /etc/X11/xdm/Xsetup:

# Virtual keyboard
/usr/X11R6/bin/xvkbd -geometry -190-52 &

Add them before the section that says:
#
# Handle background:

When you restart the X-server, the keyboard should be in the lower section of the screen. To change the position, change geometry parameters: -geometry -[x]-[y]

Power Management

To utilize power management effectively you must recompile the kernel. Note: recompiling is an involved process. The following assumes you understands recompiling and using Grub.

Kernel Source and Grub

Obtain the "kernel-of-the-day" from Google (link). For this guide I am using: kernel-source-2.6.11-20050304192700.i586.rpm. Pick the newest available kernel you find and save to a temporary file location (i.e. /tmp/kernel).

# cd /tmp/kernel
# rpm2cpio kernel-source-2.6.10-20050221200109.i586.rpm | cpio -idv
# cd ./usr/src
# mv linux-2.6.10-20050221200109 /usr/src/

Modify symbolic links for Suse bootup (depending on your installed kernel these files may differ):

# cd /boot/
# ls -la

lrwxrwxrwx   1 root root      26 Feb 19 18:28 initrd -> initrd-2.6.8-24.11-default
lrwxrwxrwx   1 root root      27 Feb 19 18:29 vmlinuz -> vmlinuz-2.6.8-24.11-default

# ln -s initrd-2.6.8-24.11-default initrd-default
# ln -s vmlinuz-2.6.8-24.11-default vmlinuz-default

EDIT /boot/grub/menu.lst:

• copy the first entry (this should becomes the second entry)
• edit the second entry (add "-default" as needed)

Now "-default" is the original, but your new kernel should load by default. For example only:

###Don't change this comment - YaST2 identifier: Original name: linux###
title SUSE LINUX 9.2
    kernel (hd0,0)/vmlinuz root=/dev/hda3 vga=0x317 selinux=0 acpi_sleep=s3_mode resume=/dev/hda2 desktop elevator=as showopts
    initrd (hd0,0)/initrd

###Don't change this comment - YaST2 identifier: Original name: linux-default###
title SUSE LINUX 9.2 (default)
    kernel (hd0,0)/vmlinuz-default root=/dev/hda3 vga=0x317 selinux=0 splash=silent resume=/dev/hda2 desktop elevator=as showopts
    initrd (hd0,0)/initrd-default

Compiling Process

First obtain my .config as a starting point. Download, unzip and save the file as .config to your /usr/src/linux-2.6.xxxxx location that you created above.

# cd /usr/src/linux-2.6.10-20050221200109
# make oldconfig
# make modules_install
# make install         (This will make the first grub entry point
                        for this kernel, but it will not change grub)

Once done, reboot the computer. Upon booting you might see an error with device-mapper. This is ok. The new kernel does not have this module. You may also see some other small errors, depending on you systems configuration.

Current Power Management Status:

• ACPI S3 does not work at this point.
• ACPI S4 does not work, but I think this will be fixed in future kernels.
• LCD Brightness Control does work and can be changed.

LCD Brightness

Test by loaing the module and changing the brightness level. Valid numbers are between 1 and 8:

# modprobe video
# echo 4 > /proc/acpi/video/VGA/LCD/brightness
# echo 1 > /proc/acpi/video/VGA/LCD/brightness
# echo 8 > /proc/acpi/video/VGA/LCD/brightness

Setup the powersave daemon to control the LCD.

Download and unzip and setup the following files: lcd_fuj_su92.tar.gz contains 2 files.
copy lcd to /etc/sysconfig/powersave/lcd
copy set_lcd_level to /usr/lib/powersave/scripts/set_lcd_level

Run: YaST. Goto System > /etc/sysconfig Editor.

• Select: System > Powermanagement > Powersave > General > POWERSAVE_ACPI_MODULES
  Add: video
• Select: System > Powermanagement > Powersave > General > POWERSAVE_ACPI_MODULES_NOT_TO_UNLOAD
  Add: video
• Select: System > Powermanagement > Powersave > Events > POWERSAVE_EVENT_ACADAPTOR_ONLINE
  After set_disk_settings, Add: set_lcd_level
• Select: System > Powermanagement > Powersave > Events > POWERSAVE_EVENT_ACADAPTOR_OFFLINE
  After set_disk_settings Add: set_lcd_level
• Select: System > Powermanagement > Powersave > Events > POWERSAVE_EVENT_DEAMON_SCHEME_CHANGE
  After set_disk_settings Add: set_lcd_level

(Optional): You may want to Edit the Scheme: "Powersave". Change the setting: Hard Disk > Stand-by Policy, to "Power Saving". This is found in "Power Management" in YaST. You can use /etc/sysconfig Editor to fine tune the settings.

If you did not do the above optional step, restart and apply the daemon:

# /etc/init.d/powersaved restart

LCD Powersaving Results: It takes a few second for the powersave deamon to react to changes, when you unplug the AC adaptor. When you unplug the AC, the display should dim. By controlling both hard disk and the LCD backlight you should improve your battery life.
