Thinkpad x61 with Ubuntu: Getting the 3rd mouse button to work.
There are two different methods I found, which work for different version of Ubuntu.
Ubuntu 8.10
First, copy/paste below
<match key="info.product" string="TPPS/2 IBM TrackPoint"> <merge key="input.x11_options.EmulateWheel" type="string">true</merge> <merge key="input.x11_options.EmulateWheelButton" type="string">2</merge> <merge key="input.x11_options.YAxisMapping" type="string">4 5</merge> <merge key="input.x11_options.XAxisMapping" type="string">6 7</merge> <merge key="input.x11_options.Emulate3Buttons" type="string">true</merge> <merge key="input.x11_options.EmulateWheelTimeout" type="string">200</merge> </match>
Then, make a new file /etc/hal/fdi/policy/mouse-wheel.fdi
sudo vi /etc/hal/fdi/policy/mouse-wheel.fdi
Insert a new line by hitting the letter i
Paste by hitting shift+ctrl+v
Save and quit by typing :wq
Reboot.
That’s it, pretty hard eh?
Ubuntu 7.10
Replace the mouse entry of your /etc/X11/xorg.conf with the following (its a good idea to back up your xorg.conf before making any changes):
Section "InputDevice" Identifier "Mouse1" Driver "mouse" Option "Protocol" "ExplorerPS/2" # IMPS/2 is not recommend for TrackPoints Option "Device" "/dev/input/mice" Option "EmulateWheel" "on" Option "EmulateWheelTimeout" "200" Option "EmulateWheelButton" "2" Option "YAxisMapping" "4 5" Option "XAxisMapping" "6 7" EndSection
Reboot.
