How can I permanently change touchpad settings?

I added this script to my startup programs to change my touchpad settings on startup:

synclient TapButton2=2 TapButton3=3

But this settings don't stay this way after startup.

I changed my script to watch the results:

synclient TapButton2=2 TapButton3=3
synclient | grep TapButton > $HOME/tmp/touchpad.txt

Results were confusing, touchpad still didn't work the way I want:

$ cat ~/tmp/touchpad.txt
TapButton1              = 1
TapButton2              = 2
TapButton3              = 3

But when I ran synclient | grep TapButton in gnome-terminal after startup the output was:

$ synclient | grep TapButton
TapButton1              = 1
TapButton2              = 3
TapButton3              = 0

I tried adding delays (sleep 10s) to my script before and/or after every line, but this didn't help too.

Therefore I assume that there is another program, script or daemon that changes touchpad settings, but I couldn't find which one.

Two questions:

• Which program, script or daemon can change touchpad settings?
• Is there another way to permanently change your touchpad settings? Maybe adding such script to startup is not supposed to be working.

Update

I tried putting

Section "InputClass"
    Identifier "touchpad my settings"
    MatchIsTouchpad "on"
    MatchOS "Linux"
    MatchDevicePath "/dev/input/mouse*"
    Option "TapButton1" "1"
    Option "TapButton2" "2"
    Option "TapButton3" "3"
    Option "PalmDetect" "on"
EndSection

into file /usr/share/X11/xorg.conf.d/99-my.conf. It didn't help as well.

Solution 1:

I've got a simple solution...

Just press the windows key and type 'startup'. You will see 'Startup applications'

• click this and then click [ADD]
• give it a name (like mousetap2)

• enter the command in the box... i.e.

  synclient TapButton2=2 TapButton3=3
  

and that's it...

It will run on startup and configure the trackpad all without pissing about with configuration files.
