I have a thinkpad X60 and I ave run various different distros on it including LM5. I use the middle mouse button to scroll windows up down, left and right. On all the previous distributions I have used I would add a few lines to my xorg.conf file along the lines of
Option "EmulateWheel" "on"
Option "EmulateWheelTimeOut" "200"
Option "EmulateWheelButton" "2"
Option "YAxisMapping" "4 5"
Option "XAxisMapping" "6 7"
Option "ZAxisMapping" "4 5"
In the configured mouse section, problem being LM6 seems to have a very spartan xorg.conf compared to what I am used to and there isnt a configured mouse section. I am not a totally new to linux but I am far from and expert either. I didnt make a backup of my previous xorg.conf as I havent needed to in the past.
If any thinkpad users could shine a little light on how to get this working I would be most greatful!
