g13-linux profile create new  # Create a new profile
g13-linux profile delete old  # Delete a profile

GUI

g13-linux-gui         # Launch the configuration GUI

Python API

from g13_linux import open_g13, G13Mapper

# Open device and start mapping
device = open_g13()
mapper = G13Mapper()

# Read events
while True:
    data = read_event(device)
    if data:
        mapper.handle_raw_report(data)

Per-Application Profiles

Automatically switch G13 profiles when you switch applications. For example, load your EVE Online profile when EVE is focused, and switch to your browser profile when Firefox is active.

Setup (GUI)

1. Launch the GUI: g13-linux-gui
2. Go to the App Profiles tab
3. Click Add Rule to create a new rule:
   • Rule Name: A friendly name (e.g., "EVE Online")
   • Pattern: Regex pattern to match (e.g., EVE - or firefox)
   • Match Type: Match against window name, WM_CLASS, or both
   • Profile: Select which profile to activate
4. Enable auto-switching with the toggle at the top
5. Click Test to see the current window's info

Configuration File

Rules are stored in ~/.config/g13-linux/app_profiles.json:

{
  "rules": [
    {
      "name": "EVE Online",
      "pattern": "EVE -",
      "match_type": "window_name",
      "profile_name": "eve_online",
      "enabled": true
    },
    {
      "name": "Firefox",
      "pattern": "firefox",
      "match_type": "wm_class",
      "profile_name": "browser",
      "enabled": true
    }
  ],
  "default_profile": "default",
  "enabled": true
}

Requirements

• X11 only: Requires xdotool for window detection (not available on Wayland)
• Install: sudo apt install xdotool

How It Works

1. A background thread polls the active window every 500ms using xdotool
2. When the active window changes, rules are matched against window name and WM_CLASS
3. First matching rule triggers a profile switch
4. If no rules match, the default profile is loaded (if configured)

Hardware

Component	Status
G1-G22 Keys	✅ Working
M1-M3 Mode Keys	✅ Working
MR Key	✅ Working
Thumbstick	✅ Working
LCD Display	✅ Working
RGB Backlight	✅ Working

Note: Button input requires either:

• udev rules for hidraw access, or
• sudo with libusb mode (g13-linux-gui --libusb)

Linux kernel 6.19+ will include native hid-lg-g15 support for G13.
