Red joystick and middle mouse keys when using the Ubuntu System in the ThinkPad notebook

Friends who are used to ThinkPad will be more accustomed to using the red joystick, because they are no less familiar with the common mouse.

However, after ubuntu (11.04) is installed, this function is not enabled by default. You can find it online and summarize it as follows:

If your system is a version earlier than ubuntu10.10, edit/etc/X11/Xorg. conf and find:

Section "inputdevice"

Identifier "configured mouse"

Driver "Mouse"

# Add the following three lines

Option "emulatewheel" "true"

Option "emulatewheeltimeout" "200"

Option "emulatewheelbutton" "2"

If your system is a version later than ubuntu10.10, find the directory/usr/share/X11/Xorg. conf. d/and create a new file 20-thinkpad.conf, that is:

CD/usr/share/X11/Xorg. conf. d/

Sudo VI 20-thinkpad.conf

Copy the following section and restart X-window:

Section "inputclass"
Identifier "trackpoint wheel emulation"
Matchproduct "TPPS/2 IBM trackpoint | dualpoint stick | synaptics Inc. Composite touchpad/trackpoint | ThinkPad USB keyboard with trackpoint | USB trackpoint pointing device | 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

In the latest ubuntu11.10, the middle and joystick functions are available by default, without any modification.

Hope to help friends in need.
