What desktop environment are you using? Some DEs have mouse/touchpad settings built-in to them.

The following is assuming that you don't have a "mouse settings" option (or similar) anywhere in your desktop environment's settings.

First, you should have the package xserver-xorg-input-synaptics installed.

Then, open a terminal and run

Code:

synclient -l

(That's a lowercase L)

It should print out a long list of settings. Among those, you should see something like:

Code:

TapButton1      = 1
TapButton2      = 2
TapButton3      = 3

This is telling it when you tap with 1 finger, act like mouse button 1 was pressed. The same is for 2 and 3, respectively.

On my laptop, setting these to zero disabled the tap-to-click (the physical buttons below the touchpad still worked like usual):

Code:

synclient TapButton1=0
synclient TapButton2=0
synclient TapButton3=0

If these commands disable your touchpad, then we have a few options. Probably the "right" way to do it is to make a file in /etc/X11/xorg.conf.d/; however, I'm not very familiar with the format of those files. Here's what I've worked out after looking at my laptop's configuration, but note that this might not be correct.

Code:

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        Option "TapButton1" "0"
        Option "TapButton2" "0"
        Option "TapButton3" "0"

There are other, more "hackish" ways to get it done, but I'd rather not go that route unless this doesn't work.

Thank you for post

I installed that package about 2 hours before I made post...typing synclient -l
gives me :

Couldn't find synaptics properties. No synaptics driver loaded?

In days of old mousedev.tap_time=0 as a kernel parm, but the modules are different now. With udev and evdev managing things you'll probably find something in xinput.

$ xinput
$ xinput --list-props 15
(or whatever # matches the device, changes between X starts / boots)
$ xinput --set-prop #D #P #V

Where #D is the device number (same as --list-props). And #P is the property # (changes between startups). And #V is the desired value. Back in the day there was also tpconfig and synaptic depending on your device. Not sure if either of those still work. Mentions of synclient in the synaptic driver for xorg.

https://wiki.debian.org/SynapticsTouchpad

A few system settings option for gnome and kde. I don't use those so I don't know what they're called or if they work. But the only option I need to change is enable middle mouse button emulation on my two button trackball. Which I can do with xinput.

xinit: no such command

OP still hasn't, as far as I can see, told us which desktop environment they are using, as requested by maples right at the start, an important piece of information when it comes to solving problems with input devices such as the touchpad.

For KDE: System Settings->Hardware->Input Devices->Touchpad->Tap Detection->Maximum time: change to 0ms.

Seems like your onto something as configuration at xorg level would be most use full for
two reasons 1. I have many installed DE and WM Gnome, KDE, Xfce4, Mate, and 2 or 3 others
And 2. I won't have to start a thread on how to get same option on FreeBSD.So installed xorg-input-synaptics then rebooted and ran synclient -l and got :

Couldn't find synaptics properties. "No synaptics driver loaded?"

Can you please paste the output from:

Code:

xinput; dmesg | grep pnp

Sorry, new to linux, don't have great social skills and this is the first forum I've ever joined. I have many desktops I just wrote them in previous post.I would prefer to learn how to do this at xorg/system level but learning how to do it in Xfce4 ,Gnome and KDE would help me in the mean time.As said in title no touch pad shows up (in any DEorWM) only a mouse. My system doesn't detect it as a touchpad but as a mouse: "ImPS/2 Generic Wheel Mouse" That's from output of cat /proc/bus/input/devices
Also don't know what this means but . . .
i801_smbus: failed to enable,can't probe, it might be i80l or i801 can't tell not sure if it's relevant thought I would share.

Welcome to the club.

Could you possibly paste the output from the command I mentioned above? That should tell us what make your touchpad is.

Ah, sorry, I didn't see your message that you had tried xinput but that you appear not to have it installed. That's the more important of the commands.

Can you install xinput from the Debian repositories?

User9 · 03-26-2016, 01:35 PM

Yes, searched xinput in Synaptics Pkg Man came up with a lot in Pkg: inputplus, Descript: xinput monitor the one ?

User9 · 03-26-2016, 01:44 PM

I scrolled down and found right pkg here you go . . . xinput:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ eGalax Inc. USB TouchController id=10 [slave pointer (2)]
