problems adjusting pointer sensitivity on Dell Latitude D830

[Mark A. Miller]

I recently bought a Latitude D830 and installed Fedora 8.  Overall I am very happy.

This laptop has a trackstick and a trackpad, and I am having trouble decreasing the sensitivity of the tackpoint.  (The trackpad DOES respond to the System->Preferences->Hardware->Mouse control panel.)

I'm guessing that I need to add an input section to xorg.conf, but I don't know what that should look like.  For example, how do I know what the trackpoint device is, what driver it uses, etc.

If I have to make the trackpoint the corepointer or even disable the trackpad, that's OK with me.

Here's my current xorg.conf, with some manual changes I made to the speed limits and with SHMConfig manually disabled.  Like I said, I'm happy with how my trackpad performs with this configuration but not the trackpoint.

Thanks in advance.
