Hello.

I'm having a hell of a time configuring my Synaptics Touchpad. Basically,
I'd like to disable the annoying "tapping" feature; with tapping, they
mean, that the user shortly "hits" (taps) the touchpad and this is then
interpreted as a click. This annoys the hell out of me, as I accidently
tap the touchpad when I type something and as a result, I continue to
type at the wrong location. Anyway, enough of the whining - I'd like to
disable tapping...

On various places on the internet, like http://linux-on-laptops.com/forum/showthread.php?t=112
or http://copland.udel.edu/~doke/dell_d810/, I found, that it should be
good enough, to add

Option "MaxTapTime" "0"

to the Section "InputDevice" in the xorg.conf file. As you can see in
my xorg.conf file at <http://askwar.pastebin.ca/453131>, I did that.
Nonetheless, I'm sadly still able to use that annoying tapping feature :(

As this did not work, I tried to use graphical configuration tools
like gsynaptics, ksynaptics or synclient to access the touchpad. All
of these tools require, that

Option "SHMConfig" "on"

is added to the xorg.conf. Instead of "on", I also tried "true", "1"
and "yes". None of these work - all the time, when I run one of the
aforementioned tools, I get an error message, stating something reg.
SHMConfig. For synclient, it is:

alexander@blattli ~ $ synclient -m 20
Can't access shared memory area. SHMConfig disabled?

I'm using on ~x86:

alexander@blattli /etc/X11 $ X -version

Is anyone able to configure a Synaptics Touchpad? If so, any idea
what I'm doing wrong?

Thanks,

Alexander Skwar
