One of the best features of my laptop [Thinkpad t61] is these laptops have trackpoints which helps you to handle the keyboard and mouse without getting your hands of the keyboard, so that you handle your jobs faster. With ubuntu the trackpoints’ scrolling property does not work out of the box, but if you follow the steps under this post, you can have fully working trackpoint functionality.
1.Step: The gpointing-device-settings should be installed on your system. 2.Step: Open a terminal and enter ” sudo apt-get install gpointing-device-settings ” , then enter your password to continue with the installation. 3.Step: After installation “ALT-F2″ and enter ” gpointing-device-settings ” to the dialog box. 4.Step: You need to select from left side the ‘IBM Trackpoint” option. then the most important thing to do is wheel emulation button has to be “2″. and enabling the features as it is seen in the picture. 5.Step: Press “Ok” and, you need to restart the system to work with the new settings.
