UPDATE Aug 08 AUTOMATIC SCREEN ORIENTATION (based on HDAPS Orientation Sensor)
(See Below).

This document describes the process of configuring Linux, Ubuntu 8.04 Hardy (release 2008) on a IBM ThinkPad X41 Tablet, with my scripts and patches to download.

ENABLE STYLUS

/etc/X11/xorg.conf

#Uncomment if you have a wacom tablet
        InputDevice     "stylus"        "SendCoreEvents"
        InputDevice     "cursor"        "SendCoreEvents"
        InputDevice     "eraser"        "SendCoreEvents"
        #InputDevice    "Synaptics Touchpad"

apt-get install wacom-tools

To download xorg.conf, for reference.

FINGERPRINT READER AND HDAPS SENSOR

/etc/modules

Add:

#Required for Fingerprint Reader
uinput  
#Thinkpad access to the embedded controller. Battery
tp_smapi  
#IBM Active Protection System and Orientation Sensor
hdaps_ec  

For Fingerprint sensor see How_to_enable_the_fingerprint_reader_with_ThinkFinger and my entry.

To try orientation sensor, apt-get install hdapsd hdaps-utils, then use hdaps-gl.
Add this to /etc/modprobe.d/options to correct orientation.

#Hdaps Orientation
options hdaps invert=3
options hdaps_ec invert=3

SCRIPT TO ROTATE SCREEN, ACPI SWIVEL EVENTS AND TABLET BUTTONS

I have made this script in /usr/local/bin/rotatetablet (it’s is based on a script by Saikat Guha found here). It rotates screen, rotates stylus, changes tablet page down/up keys, and deactivate compiz if active (Because Compiz freezes with xrand )*. Arguments are [left|right|inverted|normal] or empty for next.

Then create these 4 files to call it in response to acpi events:

/etc/acpi/events/x41t-swivel-down

# /etc/acpi/events/x41t-swivel-down
# called when tablet head swivels down

BOOT IN CONSOLE MODE, AND WITH COLORS. [OPTIONAL]

For boot in console mode:

/boot/grub/menu.lst

Add to kernel options vga=0×317 and remove splash.

kernel   /boot/vmlinuz-2.6.24-19-generic root=... ro quiet vga=0x317 nohz=off 

Then grub-install /dev/sda

In /etc/modprobe.d/blacklist-framebuffer, comment #blacklist vesafb to enable vesa framebuffer.
In /etc/initramfs-tools/modules, add

#Framebuffer modules
fbcon
vesafb

Then update-initramfs.

To activate colors I have done a patch for file /etc/lsb-base-logging.sh.
Localize the first line and comment inside lines. Leave it like this:

 if [ "$COL" ] & & [ -x "$TPUT" ]; then
        #printf "\r"
        #$TPUT hpa $COL
        #if [ "$1" -eq 0 ]; then
        #    echo "[ OK ]"
        #else
        #    printf '['
        #    $TPUT setaf 1 # red
        #    printf fail
        #    $TPUT op # normal
        #    echo ']'
        #fi
	
        #PATCH
        COLS=`$TPUT cols`
        if [ -n "$COLS" ]; then
            COL=`$EXPR $COLS - 7`
        else
            COL=73
        fi
	
        UP=`$TPUT cuu1`

SCREENSHOT, LINUX ON THINKPAD X41 TABLET

/*
UPDATE Aug 08
*/

AUTOMATIC SCREEN ORIENTATION (based on HDAPS Orientation Sensor)

Scripts (and instructions) by Dave Clawson

apt-get install libproc-process-perl (To install Perl module Proc::ProcessTree)

Download…
orientation tool: orient
orientation daemon: orientd
rotatetablet script: rotatetablet

The instructions to do this are as such:

1. Place the attached scripts (’orient’ and ‘orientd’) in /usr/local/bin and make them executable
2. Substitute /etc/acpi/x41tsup.sh and /etc/acpi/x41sdown.sh with these new versions and make sure that they’re executable.

/etc/acpi/x41tsdown.sh (with chmod +x)

#!/bin/sh
#/etc/acpi/x41tsdown.sh
	
#echo 'Rotating Tablet...'
#/usr/local/bin/rotatetablet right
	
echo 'Starting orientd...'
/usr/local/bin/orientd start

/etc/acpi/x41tsup.sh (with chmod +x)

#!/bin/sh
#/etc/acpi/x41tsup.sh
	
echo 'Stopping orientd...'
/usr/local/bin/orientd stop 
	
echo 'Unrotating Tablet...'
/usr/local/bin/rotatetablet normal

3. Put the following line in /etc/rc.local (before the “exit 0” line):

/usr/local/bin/orient reorient

…and that should do it.

NOTE: /usr/local/bin/rotatetablet needs the ‘compiz –replace’ line uncommented if you use compiz.

(Translation into English below)

Los modulos VMWARE no compilan en el Kernel 2.6.24 (No esta aun soportado).

El patch oficial vmware-any-any-update115, ftp://platan.vc.cvut.cz/pub/vmware, resuelve problemas con algunos kernels anteriores pero tampoco compila en el 2.6.24.

Peter Teoh ha creado el patch no oficial vmware-any-any-update-116.tgz que si compila en 2.6.24 modificando el modulo vmmon.tar, tomando como base el patch 115 anterior.

Pero los patch vmware-any-any-update no soportan el modo bridge con tarjetas de red wireless. Se puede leer en el source del modulo vmnet.tar, en smac_linux.x386.c:

KERN_WARNING vmnet: You are trying to use wireless bridged networking together with vmware-any-any-update. This is not supported configuration, and your wireless bridge will probably not work

Tras investigar un poco, el problema es que esta funcion solo la soporta el modulo vmnet.tar que viene con el vmware original, que incluye los binarios precompilados smac_linux.x386.o_shipped y smac_linux.x86_64.o_shipped que dan soporte a esta funcion. Pero los modulos originales no valen porque no funcionan en el kernel 2.6.24.

Tras investigar algo mas, hay una forma de conseguir que el vmware-any-any-update115 soporte esta funcion.

Las instrucciones son:

En /usr/local/lib/vmware/modules/source/ estan los modulos originales tras instalar vmware.

tar xvf vmnet.tar  // El original de vmware
mv vmnet.tar vmnet.tar_orig
mv vmnet-only vmnet-only_orig
tar xvf vmnet.tar // El de vmware-any-any-update-115
mv vmnet.tar vmnet.tar_115
rm vmnet-only/smac_linux.x386.c
rm vmnet-only/smac_linux.x86_64.c
cp vmnet-only_orig/smac* vmnet-only   //Se pasan los binarios y las cabeceras
tar ccfs vmnet.tar vmnet-only

Con esto generamos el nuevo vmnet.tar con soporte Wireless. Y con el vmmon.tar modificado del 116 podemos regenerar el vmware-any-any-update115 con soporte para Kernel 2.6.24 y Wireles Bridge.

Se puede bajar aqui: vmware-any-any-update-115-K2.6.24-WirelessBridge.tar.gz

Otras consideraciones para instalar VMWARE en kernel nuevos:

nohz=off // Como opcion al kernel para desactivar tickless
/etc/init.d/mountdevsubfs.sh // Descomentar #Magic to make /proc/bus/usb work

Testeado en Vmware Workstation 6.02, Ubuntu 8.04 (Hardy)

VMWARE Linux Kernel 2.6.24 and Wireless Bridge

VMware modules do not compile in the Kernel 2.6.24 (Not even supported).

The official patch vmware-any-any-update115, from ftp://platan.vc.cvut.cz/pub/vmware, solves problems with some earlier kernels, but it does not compile in 2.6.24.

Peter Teoh has created the unofficial patch vmware-any-any-update-116.tgz that compiles with 2.6.24 modifying the module vmmon.tar, based on the previous 115 patch.

But vmware-any-any-update patchs do not support bridge networking with wireless network cards. It can be read in the source of module vmnet.tar, smac_linux.x386.c:

KERN_WARNING vmnet: You are trying to use wireless networking bridged together with vmware-any-any-update. This configuration is not supported, and your wireless bridge will probably not work

After investigating a bit, the problem is this function is only supported in vmnet.tar module that comes with the original vmware, which includes precompiled binaries smac_linux.x386.o_shipped and smac_linux.x86_64.o_shipped which support this function. But the original modules are not worth because they do not compile in the kernel 2.6.24.

After investigating something more, there is a way to make the vmware-any-any-update115 support this function.

The instructions are:

In /usr/local/lib/vmware/modules/source/ are vmware original modules after install.

tar xvf vmnet.tar  // vmnet.tar original vmware
mv vmnet.tar vmnet.tar_orig
mv vmnet-only vmnet-only_orig
tar xvf vmnet.tar // vmnet.tar from vmware-any-any-update-115
mv vmnet.tar vmnet.tar_115
rm vmnet-only/smac_linux.x386.c
rm vmnet-only/smac_linux.x86_64.c
cp vmnet-only_orig/smac* vmnet-only   //copy smac binaries and headers
tar ccfs vmnet.tar vmnet-only

This generates the new vmnet.tar with wireless support. And with modified vmmon.tar from 116 we can regenerate the vmware-any-any-update115 with support for Kernel 2.6.24 and Wireless Bridge.

It can be downloaded here: vmware-any-any-update-115-K2.6.24-WirelessBridge.tar.gz

Other considerations to install VMware in new kernels:

nohz=off // As the kernel option to disable tickless en grub/menu.lst
/etc/init.d/mountdevsubfs.sh // uncomment #Magic to make /proc/bus/usb work

Tested with Vmware Workstation 6.02, Ubuntu 8.04 (Hardy)
