This is the mouse sectoin of my XF86Config card:
Section "InputDevice"
# Identifier and driver
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "ImPS/2"
Option "ZAxisMapping" "4 5"
Option "Device" "/dev/mouse"
EndSection
I guess you're wondering how to add mouse wheel scrolling? The line that you need to add is the ZAxisMapping. Also, probably make sure your Option "Protocol" is "ImPS/2
As for your sound card, what version of Slackware are you using? The new 9.1 includes ALSA which should detect you soundcard automagically (if it's not an obscure card). If it's an older version of Slackware I would HIGHLY recommend getting the ALSA source code from
www.alsa-project.org and install it. You can check on the alsa web site whether your card is supported.
