This page is not accurate; I've just copied it over from Installing Fedora Core 5 on a ThinkPad X41 Tablet in order to start editing/updating it for Fedora 7. Please feel free to help out with that if you stumble across this page while it is still a work in progress.

Tested and Verified on Fedora 7

Installation

Installation is straight forward; you can use the generic install instructions here.

Configuration

X Server

Basic X server functionality should work out of the box.

Desktop Effects

'Desktop Effects' work but are not enabled by default; to enable them run 'desktop-effects' and click 'enable desktop effects'. Note that these conflict with working rotation- you get either desktop effects or tablet rotation; not both.

Enabling the Stylus

Add the following lines to /etc/rc.d/rc.local:
(Note: You will need to be root to perform these two edits)

# Map stylus to a serial port
setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig


Add the lines in bold font to /etc/X11/xorg.conf:

 Section "ServerLayout"
        Identifier     "default"
        Screen      0  "Screen0" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
        InputDevice    "cursor" "SendCoreEvents"
        InputDevice    "stylus" "SendCoreEvents"
EndSection

Section "InputDevice"
      Driver        "wacom"
      Identifier    "cursor"
      Option        "Device"        "/dev/ttyS0"
      Option        "Type"          "cursor"
      Option        "ForceDevice"   "ISDV4"
      Option        "Mode"          "Absolute"
      Option        "TPCButton"     "on"
EndSection

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

Enabling Screen Rotation

Download (and verify) the following script into your path:

$ wget http://www.cs.cornell.edu/~saikat/rotate
$ chmod a+x rotate

Rotate the screen using the script:

$ rotate -h
Useage:
   rotate [left|right|inverted|normal]
 
If no option is given, rotates the screen 90 degrees to the right.

To bind the tablet's Rotate button to rotate the screen on-the-fly, add the following line to /etc/X11/Xmodmap

keycode 139 = XF86RotateWindows
Hint:
Update: Check to make sure you are using the new setkeycodes line in the Tablet Buttons section (one with 6c 120 in the command).

Wireless Network

The wireless card works out of the box- no additional drivers necessary.

Network Manager is installed by default, but is not enabled by default. To turn it on, do as root:

# chkconfig NetworkManager on

Untested on Fedora 7

Information below this line is merely copied from the Fedora Core 5 guide and has not been tested on Fedora 7.

Hibernation

Software suspend works using Software Suspend 2. To install:

# cd /etc/yum.repos.d
# wget http://mhensler.de/swsusp/download/suspend2.repo
# yum install userui-suspend2-fbsplash userui-suspend2-theme-fedorabubbles kernel-suspend2

Edit the appropriate kernel line in /etc/grub.conf and add the parameters vga=0x317 and acpi_sleep=s3_bios. For example:

title Fedora Core (<kernel.version-build>.rhfc5.cubbi_suspend2)
       root (hd0,1)
       kernel /vmlinuz-<kernel.version-build>.rhfc5.cubbi_suspend2 ro root=/dev/VolGroup00/LogVol00 rhgb quiet vga=0x317 acpi_sleep=s3_bios
       initrd /initrd-<kernel.version-build>.rhfc5.cubbi_suspend2.img

Comment out the following line in /etc/hibernate/hibernate.conf:

# ProcSetting userui_program /sbin/suspend2ui_text

Add the following lines in /etc/hibernate/hibernate.conf:

ProcSetting userui_program /sbin/suspend2ui_fbsplash
OnResume 96 setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig

Add the following lines in /etc/hibernate/ram.conf:

Distribution fedora

Comment out the following lines in /etc/hibernate/ram.conf:

# EnableVbetool yes
# VbetoolPost yes

Make the following changes (i.e. comment out the two vbetool lines, and add the return 0 line in the resume_video function) in /etc/pm/functions-intel:

resume_video()
{
(
        # /usr/sbin/vbetool post
        # /usr/sbin/vbetool vbestate restore < /var/run/vbestate
        return 0
) >/dev/null 2>&1
}

Force the use of suspend2 by editing the appropriate lines in /etc/sysconfig/pm:

HIBERNATE_METHOD="suspend2"
HIBERNATE_RESUME_POST_VIDEO="no"

Problems with a black screen after resuming can sometimes be fixed by adding the following line to the device section in /etc/X11/xorg.conf:

Option "VBERestore" "true"

Add the following file /etc/pm/hooks/40wacom:

#!/bin/sh
setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig

Tablet Buttons

Activate mappings for the tablet buttons by adding the following lines to /etc/rc.d/rc.local:

# Map tablet hardware buttons
setkeycodes 6e 109 6d 104 69 28 6b 1 6c 120

Fingerprint Reader

The fingerprint reader is supported through the BioAPI framework. The BioAPI framework and the UPEK fingerprint reader driver can be installed as follows:

wget http://www.cs.cornell.edu/~saikat/libbiometrics-1.2.2-1.sg.i386.rpm
wget http://www.cs.cornell.edu/~saikat/libbiometrics-tfmess-1.0-1.sg.i386.rpm
yum localinstall libbiometrics-1.2.2-1.sg.i386.rpm libbiometrics-tfmess-1.0-1.sg.i386.rpm
NOTE!
This is still work-in-progress. Currently you can enroll fingerprints, and verify them through a test application. Integrating

this support into pam (and therefore logins, gdm, screensaver etc.) is in the works. Those interested in developing biometrics applications

can install libbiometrics-devel-1.2.2-1.sg.i386.rpm. SRPMS for the above are available here.

To try out enrollment and verification, run: # useraddbio

Harddrive Active Protection System (HDAPS)

Harddrive active protection system requires the hdaps kernel module (included in stock Fedora kernels), and a kernel capable of parking disks (patch included in kernel-suspend2 RPMs from the Hibernation section above). It also requires a userspace daemon to monitor the accleration sensor and park the disk head when excessive motion is detected. To install the userspace daemon, do the following:

Hint:
This requires kernel support for hdaps and head parking. Install kernel-suspend2-2.6.16-1.2084_2 or higher
# wget http://www.cs.cornell.edu/~saikat/hdapsd-20060326cvs-1.sg.i386.rpm
# yum localinstall hdapsd-20060326cvs-1.sg.i386.rpm

If software suspend is enabled, add the following line to /etc/hibernate/hibernate.conf

UnloadModules hdaps

To install the Gnome panel applet that monitors the state of the harddisk, install:

# wget http://www.cs.cornell.edu/~saikat/gnome-applet-hdaps-20060120cvs-1.sg.i386.rpm
# yum localinstall gnome-applet-hdaps-20060120cvs-1.sg.i386.rpm
NOTE!
SRPMS for the above are available here.

Software

tpb/on-screen display

tpb, which controls the onscreen display of thinkpad buttons, is not installed by default.

To install tpb execute:

# yum install tpb

Java 1.5

Install Sun's JRE 1.5. This is required for the jarnal program below.

  • Download the build: $ wget http://mirrors.dotsrc.org/jpackage/1.6/generic/non-free/SRPMS/java-1.5.0-sun-1.5.0.06-1jpp.nosrc.rpm
  • Create the build environment: # rpm -Uvh java-1.5.0-sun-1.5.0.05-1jpp.nosrc.rpm
  • Download the JVM from Sun's Java page and download jdk-1_5_0_06-linux-i586.bin to /usr/src/redhat/SOURCES
  • Build the RPMs: # rpmbuild -ba /usr/src/redhat/SPECS/java-1.5.0-sun.spec
  • Install the JVM: # yum localinstall /usr/src/redhat/RPMS/i586/java-1.5.0-sun-1.5.0.06-1jpp.i586.rpm
  • Install the fonts: # yum localinstall /usr/src/redhat/RPMS/i586/java-1.5.0-sun-fonts-1.5.0.06-1jpp.i586.rpm

Note: This is tailored for the latest JVM as of writing this article. Substitute the latest version numbers if this doesn't work.

Jarnal Note-Taking

Install the Jarnal note-taking application:

# wget http://www.cs.cornell.edu/~saikat/jarnal-8.14-1sg.noarch.rpm
# yum localinstall jarnal-8.14-1sg.noarch.rpm
NOTE!
SRPMS for the above are available here
