Description Jacob Masaki 2007-11-11 00:09:53 EST
Description of problem:

Version-Release number of selected component Kernel 2.23.1-49:

How reproducible:

Steps to Reproduce:
1. Install Fedora 8 + Updates
2. Find that xorg won't load the "synaptics" driver because it thinks the
touchpad can't use synaptics.  
Actual results:
Touchpad is thought to be a normal mouse.  

Expected results:
Touchpad is though to be a touchpad, so scrolling works and such.  

Additional info:
http://lkml.org/lkml/2007/8/4/184 Talks about a possible fix, but I haven't
tried it, as I've never compiled a kernel before, and am worried I will render
my laptop unbootable.  

I also looked at the Ubuntu source (Ubuntu works with the touchpad) and they
appear to have applied this patch in the alps.c (and a couple others, which I
hope are unrelated...)

I can also confirm this bug with kernel 2.23.1-49 on my Dell Vostro 1400 with 
FC8 and all updates installed.

Can confirm that trackpad scrolling etc for Dell Inspiron 1420 now works with
kernel (was not working with

Some of the numbers for the synaptics driver options in xorg.conf have to be
tweaked quite a bit to get it usable, but once that's done it works ok.
