I have followed the instructions from here exactly. I was able to increase the speed and sensitivity of my trackpoint. However, those settings would revert itself to the default upon restart. In other words, the settings don't save.
What am I doing wrong? I'm using Ubuntu 12.04 on a Lenovo ThinkPad X120e that has an AMD 64-bit processor. Please someone help me with this, as I cannot use the touchpad, and I will have to dump Linux and go back to Windows if I don't have proper trackpoint support.
