MacBook touchpad and latest kernel

Hi everybody,

My first post! I'm having some problems with the latest release of the kernel (kernel26-2.6.24.4-1). After rebooting the system the touchpad doesn't work anymore (But yes with usb mouse). I been trying to reinstall the kernel26 package and synaptic but nothing, still same. My MacBook (white) is a Core 2 Duo 2.20GHz bought in December 2007. 

xorg.conf (Synaptics section)

Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option          "SendCoreEvents"        "true"

Any tip or help?

Re: MacBook touchpad and latest kernel

Do you have the appletouch module loaded?
It should be autoloaded but this would be the first thing I'd check.

Re: MacBook touchpad and latest kernel

I have a macbook with the same specs as yours and I'm not having any problems with the touchpad.

Do you have this in your ServerLayout section??

        InputDevice    "TouchPad" "SendCoreEvents"

also, I'm using /dev/input/mouse1 as the device instead of /dev/psaux

Section "InputDevice"
        Identifier      "TouchPad"
        Driver          "synaptics"
        Option          "SendCoreEvents"

Re: MacBook touchpad and latest kernel

Solved! The problem was in the ServerLayout because I had a different InputDevice for the TouchPad that for some reason was not working with the latest kernel.

tizoc, do you also have right click working on your macbook?

thanks everybody

Re: MacBook touchpad and latest kernel

miguimon, yes, if I tap the upper right corner of the touchpad that works as the right click, and the upper left corner works as te middle click (LTCornerButton and RTCornerButton options).
