t’s that special time of year again! I have just finished upgrading my trusty ThinkPad T61 to the latest version of Ubuntu Linux — 10.04 Lucid Lynx. This edition of the operating system no longer employs the udev method of emulating scrolling. With the following instructions, one will be able to scroll with the middle button both vertically and horizontally:

Step 1. Create a new file

sudo vi /usr/lib/X11/xorg.conf.d/20-thinkpad.conf

Step 2. Insert the following

Section "InputClass"
Identifier "Trackpoint Wheel Emulation"
MatchProduct "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint"
MatchDevicePath "/dev/input/event*"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"
Option "Emulate3Buttons" "false"
Option "XAxisMapping" "6 7"
Option "YAxisMapping" "4 5"
EndSection

Step 3. Save file, restart computer, and enjoy!

Please comment and let me know whether this solution worked for you, or if you have alternative methods.

By the way, I’m not able to get the fingerprint reader working. Has anyone had any luck with it? Any tips to share?
