Touch Pad Sensitivity

[Lovell Mcilwain]

Hello All,

Is there a way that I can decrease the tap sensitivity or turn off the
 tap option on my touch pad?

I am having this annoying problem that when I am typing my palm or some
 part of my hand brushes up against the touch pad and starts me typing in
 another part of the text that I have already typed.  I thought I could
 live with it but I really can't  :) .  I tried changing my typing so my
 wrists are up higher but no luck.  So now I would like to try turning
 off the tap option (if there is a way to do that) and see if I am better
 off without it.

I am using Fedora Core 4 on a Compaq Presario R3000

Thanks,

Lovell

In the "InputDevice" section you can add the option MinTapTime @ ~.25. Here
are some examples of what other people have done.

Section "InputDevice"
        Identifier      "Alps Touchpad"
        Driver          "synaptics"

Thanks Dave for the tip but where can I find this file that this needs 
to be added to? and does it matter where I add that line?

Look in /etc/X11/xorg.conf

I tried adding that entry but it doesn't seem to have worked. Is it 
possible that I added the entry wrong?  Right now I have the entry 
specified as:

option MinTapTime "@ ~.25"

Is there another way I should specify it?

sorry  I was lazy and meant that you should specify a value at or around .25
Example:

option MinTapTime ".25"

Is this a Synaptics touchpad?  If so, you probably have the synaptics RPM 
installed.  It includes a program called syndaemon, which disables the 
touchpad while you are typing.

I haven't felt the need, but it might do the job for you.

Here is what happened when I tried to run syndaemon:

[user@Blade ~]$ sudo syndaemon -t -d
Can't access shared memory area. SHMConfig disabled?

I tried to find SHMConfig but didn't see a man page for it or couldn't 
locate it anywhere.  Can you tell me what I might be missing?  I also 
didn't see the syndaemon in the services list via the gui if that helps.

Look in /etc/X11/xorg.conf for

Section "InputDevice"
         	Identifier  "Synaptics"
            Driver      "synaptics"
    ...
    EndSection

and add the line

Option      "SHMConfig" "on"

in a line between the Section and EndSection lines.  Then restart X.

See /usr/share/doc/synaptics-0.14.0/README for more things you can 
configure.

syndaemon doesn't come with a startup script.  You can invoke it in 
/etc/rc.local.

Thanks for all the help, it does exactly what I want it to do.  Sorry it 
took me so long to respond but I finally got a chance to reboot my 
machine after changing my xorg.conf file.  Forgive me for not being able 
to know how to restart the xserver from the command line :)
