IBM thinkpad. scrolling with the eraserhead?

[ericb]

anybody have any idea how one would go about making X accept scrolling with the trackstick in the middle of the keyboard.

in windows if you hold down button 3 and move the trackstick windows will scroll.

in linux i'm not really sure where to begin with that. is trackstick movement sensed as another button by x so z-axis mapping would work?

Yeah, I am pretty sure it is seen as new buttons. You can try setting it up like a wheeled mouse and see if that does the trick.

if im not mistaken, I believe you set it up as a regular ps2 mouse.

go to www.linuxdoc.org (http://www.linuxdoc.org) and check the Laptop-HOWTO

it is set up as a regular mouse. the trackpoint works just fine. now i want to scroll with it since i'm not content to believe that i can't do it in linux when i can do it in windows.

ok. this is the basic setup of the pointer on an IBM thinkpad T20. the P is the pointer in the middle of the keyboard and below the spacebar are the 3 buttons.
there is one widebutton at the bottom and two buttons half as wide directly above it. those are the right and left clicking buttons. the bottom one is button3

in windows you hold in button 3 (the big one at the bottom) and move the pointer to scroll windows.

the strange things is that 'xev' reports the second button that is used for right clicking as button 3 and the big button as button 2.


my goal is to make the scrolling functionwork in linux, but xev does not report holding in the big button and moving the pointer as a button press so ZAxisMapping does not seem to be a valid option.

any ideas would be greatly appreciated. thanks.
