Logitech G600 on Linux

Utility program for binding actions to keys on the Logitech G600 gaming mouse. Supports 16 keys and the G-shift button for a total of 32 fast shortcuts. g600.py can be configured to set program specific bindings.

Before running this program open the Logitech Gaming Software on a Windows or Mac OS machine. Assign the three basic mouse buttons to their standard functions. The G-shift button should be assigned to the G-shift function. All the remaining buttons (scroll left, scroll right, G7, ... G20) should be set to emulate (unique) keyboard keys (but not modifier keys).

Usage

1. Clone this repository.
2. Open g600.py and fill in the commands for the keys.
   • Set default bindings in DEFAULT_BINDINGS
   • Set program specific bindings in CUSTOM_BINDINGS
3. Compile with gcc g600.c -o g600.
4. Run with sudo ./g600.

For command ideas you can look at programs like xdotool, xdo, pulseaudio-ctl, xclip, i3-msg. You can also run your own scripts.

The program needs privileges to communicate with G600 so typically it'll be started with sudo. Alternatively (works on Ubuntu 18.04) you can force the program to run as the input group with:

sudo chown .input g600
sudo chmod g+s g600

Notes

When doing initial configuration through Logitech Gaming Software, the G-shift + G9 ... G20 keys should be changed from their default bindings Ctrl+1, Ctrl+2, etc, to something like A, B, etc. Not doing so caused all keys with a Ctrl+num binding to emit the same signature thus unable to assign them different bindings.

To find the name of a program to add to CUSTOM_BINDINGS run 1) xprop WM_CLASS, 2) click program, 3) use the first value from output as key in CUSTOM_BINDINGS.

Depending on when your G600 mouse was purchased, your mouse scancodes may be different from my config. Run ./g600 and press around your mouse buttons to see its scancodes. Change the scancode in downCommands, upCommands if needed, then recompile g600.c.
