ASUS Laptop function key inop

Problem: After a Live CD install of 7.10 Gutsy on ASUS C90S notebook most, but not all, function keys work.

1) Inspection of ACPI log shows message "... is SHMConfig installed?"
2) Examining /etc/acpi/asus-touchpad.sh script shows that 'synclient -l' output is needed to build the shell command to toggle the touchpad.
3) At the command line, 'synclient -l' outputs "Can't access shared memory area. SHMConfig disabled?"
4) Added 'Option "SHMConfig" "on" into xorg.conf as follows:
Section "InputDevice"
        Identifier "Synaptics Touchpad"
        Driver "synaptics"
        Option "SendCoreEvents" "true"
        Option "Device" "/dev/psaux"
        Option "Protocol" "auto-dev"
        Option "HorizScrollDelta" "0"
        Option "SHMConfig" "on"
EndSection
5) Restart X and touchpad function key toggle works.

Conclusion: Have Ubuntu Gutsy setup add necessary line to config on intial installation.
