Disable tap-to-click on external touchpad

tqk · 02-28-2015, 06:49 PM

I have an external touchpad as part of a keyboard/touchpad/usb-hub combination, the "Perixx PERIBOARD-515H PLUS". The device works as soon as I plug it into my laptop (which is running Ubuntu 12.04), but I don't know how to disable the tap-to-click feature.

I use KDE. In the system settings, the only touchpad that shows up in the input device section is the one which is built in to the laptop (this one does have tap-to-click disabled).

The lines from the output of lsub relevant to the external device are

Quote:

Bus 001 Device 009: ID 058f:6254 Alcor Micro Corp. USB Hub
Bus 001 Device 010: ID 04d9:a088 Holtek Semiconductor, Inc.

And here is what xinput shows:

Quote:

$ xinput list

↳ HID 04d9:a088 id=16 [slave keyboard (3)]

The external touchpad is the one with id=15.

There are various driver options that I could change (see the list below) but, based on their names, it doesn't look like any of them would control tap-to-click.

Looking at /var/log/Xorg.0.log, it appears that as a result of the InputClass "evdev pointer catchall", the evdev driver is used for the touchpad, instead of the synaptics driver (which does have settings for controlling tapping).

I tried forcing the touchpad to use the synaptics driver by appending the following to my /usr/share/X11/xorg.conf.d/10-evdev.conf file:

Quote:

Section "InputClass"
Identifier "perixx"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event10"
Driver "synaptics"
EndSection

However, this resulted in the touchpad not working at all, and a "Synaptics driver unable to detect protocol" error in /var/log/Xorg.0.log:

Ideas?

First of all, I'm not a well versed linux user so take my words with a grain of salt.

You can check if https://launchpad.net/touchpad-indicator or http://kde-apps.org/content/show.php...content=113335 are of any use for this problem.

On the file you've edited you can try to add:

Quote:

Option "Protocol" "auto-dev"
Option "MaxTapTime" "0"

Info on the generic driver http://manpages.ubuntu.com/manpages/...4/evdev.4.html

Don't know if playing with synclient command (for synaptics) or tpconfig will be of any use.

Cheers

Thanks for your response.

The touchpad-indicator sounds like it might let me enable/disable the touchpad, but that's not what I'm trying to do. kcm_touchpad is "for synaptics-driven touchpads", so I don't think it would let me control my touchpad until I get it to use the synaptics driver.

If I could use the synaptics driver, then I could just set MaxTapTime as you said to disable tap-to-click.

According to the synpatics man page, there are four possible values for the protocol: auto-dev, event, psaux, and psm. I tried setting each of them; unfortunately, none of them worked. The error messages I got are below.

With auto-dev:

I didn't realize the links provided where rather old, sorry about that.
The touchpad-indicator now has support for touchpad events.

Install instructions:

Code:

sudo add-apt-repository ppa:atareao/atareao
sudo apt-get update
sudo apt-get install touchpad-indicator

The kcm_touchpad is old. There's a newer package: kcm-touchpad.

Hope someone else can help you get it working. Some other things you might discard/consider in the meantime:

According to the synaptics(4) - Touchpad Input Driver Linux Man Page:

Quote:

The name "synaptics" is historical and the driver still provides the synaptics protocol parsing code. Under Linux however, the hardware-specifics are handled by the kernel and this driver will work for any touchpad that has a working kernel driver.

Do you have the xserver-xorg-input-synaptics package installed?

Don't know if using SendCoreEvents will make any difference...

Code:

Option	"SendCoreEvents"	"true"
MatchIsTouchpad "on"

...and also don't know (

here) if the touchpad has to be added to the xorg ServerLayout section.
