How do I enable touchpad-tapping?

[rafal_rr]

Hello everyone. I am new in this forum. Knoppix is a great Linux distro. I write a software for an old computer, without mouse and keyboard - only with touchscreen (i think - it use the same drivers like touchpad, so I'm testing my application on laptop). But touchpad-tapping (i want to it mean click) i disabled. I have downloaded synaptics drivers from repositories, but it still not works. What I must do to enable it? Change something in /etc/X11/xorg.conf ? Thank you in advance, rr

There are two ways to go about this, as you have noted, one is to modify /etc/X11/xorg.conf. Because knoppix xorg.conf is script generated, you will have understand the needed syntax and as well as understand which script is the one generating it.

Alternatively, this is what I would do it. Firstly make sure you have this program 'synclient', check that it exists :-

        $ synclient -l

( this will list all the available settings ).

If it does not exist, you would have to install xserver-xorg-input-synaptic.
After that go to /etc/X11/Xsession.d and add a file say '15x11-synaptics' with this content :-

#
synclient "TapButton1=1"

That's all which is needed. After you restarted Xserver, tap-to-click will be working.

Thank you for providing this valuable information.

I use the command

synclient TapButton1=1 TapButton2=3 TapButton3=2

to enable tapping with two and three fingers. Tapping with two fingers is set to button 3 because clicking with the right button is more often than clicking with the middle button.

You are fully justified to use tap-to-click on a system without keyboard and mouse.

I use touchpad on a typical notebook, personally I consider tap-to-click a nuisance.

However I do this :-

synclient "HorizEdgeScroll=1"

to allow me to use horizontal scroll on the edge of the touchpad.
