I am trying to get my mouse touchpad to work in Ubuntu. I found the link below and that got me to the file "xorg.conf" I haven'ta clue what to do in it. When I go to System/Pref/ Touchpad I get this error

GSynaptics couldn't initialize.
You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config to use GSynaptics

What do I need to change to true???
Please Help

Add:


Option "SHMConfig" "true"

right after:


Option "HorizEdgeScroll" "0"

Save and reboot.

AFAIK, Intrepid xorg.conf is different from the older versions where u need to tweak it for the SHMConfig.

To enable this for Intrepid, here is the official guide
