Setting up Thinkpad X41 Tablet in Ubuntu

Fingerprint reader

1. install thinkfinger (sudo apt-get install thinkfinger-tools libpam-thinkfinger)
2. acquire fingerprint (sudo tf-tool --acquire)
3. verify fingerprint (sudo tf-tool --verify)
4. update pam config (sudo gedit /etc/pam.d/common-auth so it contains only these 2 lines: auth sufficient pam_thinkfinger.so auth required pam_unix.so try_first_pass nullok_secure
   update for ubuntu 8.10: change the according lines in this file so it looks like this: ... # here are the per-package modules (the "Primary" block) auth sufficient pam_thinkfinger.so auth [success=1 default=ignore] pam_unix.so try_first_pass nullok_secure # here's the fallback if no module succeeds ... here is fix for situation when auth won't proceed until you press enter

Back/Forward keys

update for ubuntu 8.10: you can skip this step as the keys work out of the box

run sudo gedit /etc/X11/Xmodmap,

add: keycode 234 = XF86Back keycode 233 = XF86Forward
for immediate effect run xmodmap /etc/X11/Xmodmap (Note: this works in hardy, you may need to use Xmodmap instead in older versions of Ubuntu)

Trackpoint scrolling

sudo gedit /etc/X11/xorg.conf, locate section InputDevice with identifier Configured Mouse, add Option "EmulateWheel" "true" Option "EmulateWheelButton" "2"
