How to enable SHMconfig on Ubuntu 11.04? I'm trying to change touchpad's configuration on run-time, but can't because it needs for SHMconfig to be enabled, how can I do that?

I think you can add Option "SHMConfig" "true to /usr/share/X11/xorg.conf.d/50-synaptics.conf which may look like this:
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
Option "SHMConfig" "true"
EndSection
Or temporarily you can do synclient SHMConfig=1 in terminal to check the behaviour you want.

Is this for the synaptics driver?
It's been a while since I've needed this as I don't have a laptop that requires it, but under previous versions you could do this with a HAL policy:
First, create the file
/etc/hal/fdi/policy/11-synaptics-options.fdi
with the following contents:
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" contains="synaptics">
<merge key="input.x11_options.SHMConfig" type="string">On</merge>
<merge key="input.x11_options.MaxTapTime" type="string">0</merge>
</match>
</device>
</deviceinfo>
(I've added MaxTapTime=0 to turn off tap-to-click)
Restart the haldaemon, then restart X11.
After that, gsynaptics should be able to communicate via SHMConfig.

I can't find the /etc/hal/fdi/policy/11-synaptics-options.fdi I think that the migration from hal to Udev have purged them.– ashamsCommented Jun 30, 2011 at 11:35

How does one restart the haldaemon? I can't seem to find this. If it's not installed, then will these instructions not work for my 11.04 Sony Vaio VPCF136FM?– jmort253Commented Aug 28, 2011 at 4:08
