Note:

This software is no longer being updated, mainly due to Python's performance limitations. (see Abs-C for a replacement, allowing for significantly reduced latency and CPU usage, as well as Wayland support.)

I might also archive this repo at some point.

Abs

I created this program as a Linux alternative for apsun's AbsoluteTouch, as I had recently switched to Linux, and couldn't find any alternatives.

Do note that I am still very new to Python (And Git, for that matter).

Please do not hesitate if you have any sugesstions, questions etc.

Tested on Linux Mint 19.1

Prerequisites

• A laptop with a Synaptics touchpad (others may work, check if the device reports ABS_X and ABS_Y)

• Python 3.6.7 (other versions are untested, but might work).

• python3-evdev

• python3-xlib

• numpy

Setup

Optional - run setup.sh as root (note that this script will not work on non Ubuntu/Debian-based distros.)

Or manually install:

sudo apt-get update
sudo apt-get install evtest python3-evdev
pip3 install python3-xlib numpy

Note:

If you have previously added your user to the input group, then I strongly recommend you undo this change using:

sudo gpasswd -d $USER input

I say this because i've since discovered that this is a security risk, allowing all programs read access to all input devices, without root.

Configuration

I have not yet implemented a config file, so all configuration must be done in the code itself.

See the config section of Abs.py for more info.
