TouchPad(Synaptic) Tuning tool for Lxde

Sometime, I face the problem of TouchPad configuration in Lubuntu. My laptop have a too sensitive TouchPad.

This tool configure the touchpad through xinput with GUI, and no need to gnome or another heavy environment/dependencies.

Requirement

• python and python-tk
• xinput command

In lubuntu

for Python3

$ sudo apt intall python3
$ sudo apt intall python3-tk
$ sudo apt intall xf86-input-synaptics

for Python2

$ sudo apt intall python
$ sudo apt intall python-tk
$ sudo apt intall xf86-input-synaptics

How to use

$ git clone https://github.com/kuri65536/touchpadtuner.git
$ cd touchpadtuner
$ python touchpadtuner2.py

note-toggle-touchpad.py

append the script shortcut into your openbox configuration file. in my case (Lubuntu): ~/.config/openbox/lubuntu-rc.xml.

    <keybind key="XF86TouchpadToggle">
        <action name="Execute">
            <command>bash -c 'eval $HOME/bin/note-toggle-touchpad.py'</command>
        </action>
    </keybind>

then reload the configuration file by command (or reboot your computer.)

$ openbox-lubuntu --reconfigure

note-toggle-display.py

same as touchpad.

    <keybind key="W-p">
        <action name="Execute">
            <command>bash -c 'eval $HOME/bin/note-toggle-display.py'</command>
        </action>
    </keybind>

my laptop (E203NA) FN+f8 key generate the events

• keydown: state 0x0, keycode 133
• keydown: state 0x40, keycode 33
• keyup: state 0x40, keycode 133

keycode 133 is Super_L, so keybind is W-p .

TODO

• Write down or modify file: /usr/share/X11/xorg.conf.d/70-synaptic.conf, to make the changes to permanent.

• Made GUI for some missinL params. ( I solved the sensitive touchpad with below prameters, and did not use another params.)

  • FingerLow and FingerHigh
  • PalmMinWidth(1000) and PalmMinZ(500)

• xconf.save: implement NProp.is_default()

• (my touchpad problem) Incorrect scroll up/down in typing.

• (my touchpad problem) Syndaemon stop with two finger scroll.
