What it does

G213Colors lets you set the color(s) and certain effects of the illuminated keys on a G213 keyboard and G203 mouse under Linux.

Since Logitech is mostly ignoring the Linux market with their "Logitech Gaming Software" but i also wanted to use my expensive new keyboard also under linux without tolerating the color cycling animation all the time. So i searched on the internet and added a gui to SebiTimeWaster's project for comfortable usage.

G213Colors was built and tested under Linux for the G213 keyboard and G203 mouse specifically, but after some adaptation it could potentially be run under other OS'es and used for other Logitech devices as well.

If you have any Logitech keyboard or mouse that is not supported feel free to open an issue and/or contact me via Email: git(AT)eiselecloud(DOT)de

The "Wave" color effect that is available with the Logitech software could not be replicated since it is completely generated in the software by updating the colors every x ms (In contrast to the other effects which run on the keyboard itself). You could generate this effect with a script, but since G213Colors has to detach the kernel driver from one of the G213's interfaces to send data out the multimedia keys would most likely stop working. Unfortunately this is a side effect of the linux driver structure.

Installation

Clone this project with git and run sudo make install

Remark: The PyUSB and PyGObject libraries can be installed with (Running Ubuntu) running the fix.sh file or by pasteing:

sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-3.0
pip install pycairo PyGObject
sudo make install
sudo python main.py

The desktop entry didn't work for me. In case your python is not found for sudo, check your python with whereis python using the normal user. For example I had to replace the last python command with sudo /home/user/miniconda3/bin/python main.py

Prerequisites

• Python 3.x (which is usually already installed)
• PyUSB (please see their instructions on how to install)
• PyGObject

Please ignore the pcap directory, SebiTimeWaster added the pcap files he used for reverse engineering just in case someone wants to work with them. They can be opened with Wireshark.

Usage

Automatic

You can find the app in your menu after installation.

Manually

You can call the main.py script like this:

python main.py

G213Colors needs to be run as root as long as long as your user doesn't have access privileges for the USB device. In order to run the program without root privileges you have to create a udev rule for your device and add your user to the plugdev group. See how this is done on stackexchange. idVendor is 046d for Logitech. idProduct depends on your device. Use lsusb | grep Logitech to determine the Id.

Restoring previous state

After rebooting your pc you can restore the pre-reboot state by running the app with parameter -t

sudo g213colors-gui -t

You can also do this automatically at reboot by enabling the systemd service.

sudo systemctl enable g213colors.service
