SHMConfig doesn't work in gutsy

I'm confirming that the setting of SHMConfig does not seem to work on Gutsy so Touchpad attributes cannot be set. In addition, when I open a terminal window I see the following error at the top: "Can't access shared memory area. SHMConfig disabled?"

I've checked the /etc/X11/xorg.conf file and under the Synatpic Touchpad section I do see:
Option "SHMConfig" "on"
I've tried changing this to "true" but neither seem to affect the error message and SHMConfig stays disabled.

I have that same issue. 'Option "SHMConfig" "true"' does not work. 'Option "SHMConfig" "on"' does not work. Even booting off a LiveCD of Gutsy, editing the xorg.conf, installing gsynaptic and restarting X, does not work. I have a ZT laptop, which is a rebranded MSI.

configure your "SHMConfig" above your scroll option
then place the whole section above the mouse "InputDevice"
as mine is bellow, this fixed my srolling and all my touchpad related problems
also you can try changing your scroll line to match mine, that was another change i added

Section "InputDevice"
 Identifier "Synaptics Touchpad"
 Driver "synaptics"
 Option "SendCoreEvents" "true"
 Option "Device" "/dev/psaux"
 Option "Protocol" "auto-dev"
        Option "SHMConfig" "on"
 Option "HorizScrollDelta" "0"
EndSection

Section "InputDevice"
        Identifier "Configured Mouse"
        Driver "mouse"
        Option "CorePointer"
EndSection
