[clue-tech] Touchpad and xorg.conf.

[David L. Anselmi]

I had said I was going to figure out making my touch pad work with my 
track point at installfest (on a z61t).  I didn't work on that last week 
but I tried today.

Turns out all I had to do was add the input driver for it 
(xserver-xorg-input-synaptic in debian).  But the xorg.conf is rather 
misleading.  It turns out that by default the input sections using kbd 
and mouse are ignored (because hal knows better, naturally).  So hal had 
been setting up the track point fine.  I thought it might be recognizing 
the touchpad because there was a section about Mac mouse emulation (the 
touchpad only had two buttons so maybe Mac mouse stuff has to do with 
that--not).

I like the way evdev gives me 10 event devices in /dev/input (those are 
what get used with Xorg now) but "The  mapping from device node to 
hardware is system-depen-dent." (and apparently undocumented)
