I have Sabayon installed on my Sager and I just compiled the 30 kernel from source, the only modules I removed from the default kernel where the one's that where for the AMD processor (Its an intel so I figure it was safe to remove those) but anyway I loaded up X to discover that the scroll function on my touch pad failed to work Any idea which module I need to add back in when I recompile to get this function working?

Yesterday I had this issue and went to post like you, but I did click on 'find similar threads' Try this in xorg.conf

Identifier "Touchpad"
Driver "synaptics"
Option "SendCoreEvents"
Option "Protocol" "auto-dev"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
Option "SHMConfig" "on"
EndSection

Apparently you need the synaptics driver. Works well here, and my windows nerd son is no longer able to laugh at primitive desktops.
You have to tell configure that bit to be used, Here's my bit of that.
and you can see the change I made

Section "ServerLayout"

Identifier "Simple Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
# InputDevice "Mouse1" "CorePointer"
InputDevice "Touchpad" "CorePointer"
InputDevice "Keyboard1" "CoreKeyboard"
EndSection

For my laptop, it is 'psmouse' which is not functioning correctly.
See http://www.linuxquestions.org/questi...module-713868/

We are talking 2 different kinds of modules.
psmouse is a kernel module, and may indeed not function correctly.
synaptics in an X driver, specified in xorg.conf.
From http://www.linuxquestions.org/questi...module-713868/
removing & reloading a module is not fixing anything, it's working around something

By all means, if it sorts your problems do it. Does it?
