Fujitsu Stylistic ST4110 Tablet PC

This guide is how to setup SuSE 10.1 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.

NOTE: This guide is based on Fujitsu Stylistic ST4110 Tablet PC using SUSE 9.2.
Please entirely read the old guide first befor you start!

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:

• LSB packages
• Compiler & Tool packages
• 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.

First Login

You should see the KDM login and xvkbd. The SuSE 10.1 handles the xvkbd setup but not the pen.

Tablet and Pen Setup

I am providing: my updated /etc/X11/xorg.conf file with necessary changes: xorg_fuj_su101.tar.gz.

Font Issue: If you do NOT want very large fonts. In xorg.conf, 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.

After the above changes are made, reboot or restart X. The pen should work now.

Power Management

To utilize power management you no long need to recompile the kernel.

Grub

EDIT /boot/grub/menu.lst:

You need to add "acpi=s3_mode". For example only:

###Don't change this comment - YaST2 identifier: Original name: linux###
title SUSE Linux 10.1
    root (hd0,0)
    kernel /vmlinuz root=/dev/hda5 vga=0x317 resume=/dev/hda3 acpi=s3_mode splash=silent showopts
    initrd /initrd

EDIT /etc/X11/xorg.conf:

You need to enable VBERestore. For example only:

Section "Device"
  BoardName    "i830"
  BusID        "0:2:0"
  Driver       "i810"
  Identifier   "Device[0]"
  VendorName   "Intel"
  Option       "VBERestore" "on" #Needed for ACPI S3
EndSection

Current Power Management Status:

• ACPI S3 should 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

To setup the powersave daemon to control the LCD, use the SuSE 9.2 instructions.

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.

Tablet Buttons

The key driver is a work in progress. It is available through sourceforge.net under a GPL license.
