My Tablet PC has a jog dial (typically used for scrolling up and down) but it does not work by default in Ubuntu 9.10 — how can I make it work?

by

I have an HP Compaq TC4400 and I recently was able to make most of the Tablet PC functions work in Ubuntu 9.10. (The step-by-step guide can be found in my blog.) Unfortunately I have yet to make the jog dial work. This would be particularly useful for scrolling up and down websites and documents when the TC4400 is in slate mode (with no access to the keyboard).

I would be much obliged if anybody could tell me:

  1. How to find out the input button/key assignment that Ubuntu 9.10 has for jog-up and jog-down;
  2. How to assign jog-up to scroll up (D-pad key UP, or PAGE UP) and jog-down to scroll down (D-Pad key DOWN, or PAGE DOWN).

I am using xbindkeys to assign different shortcuts to the quick launch buttons, perhaps I could use the same program for the jog dial? I would have done that, except I do not know how to find the proper button/key assignment for xbindkeys to use.

Thanks in advance!

Answer

Run xev in a terminal window. If the jog wheel is detected, an event should show up.
