Razer Control Center for Linux - button remapping, macros, RGB lighting, and DPI control

Razer Control Center for Linux

A Synapse-like control center for Razer devices on Linux. Configure button remapping, macros, RGB lighting, and DPI settings.

Features

• Button Remapping: Remap mouse buttons and keyboard keys to different keys, chords, or macros
• Macro Support: Create and execute macro sequences with key presses, delays, and text input
• Multi-Layer Bindings: Support for multiple binding layers with hold-to-shift (Hypershift-like)
• Profile Management: Multiple profiles with per-application auto-switching
• App Watcher: Automatic profile switching when applications gain focus (X11/GNOME Wayland)
• OpenRazer Integration: Control RGB lighting, brightness, and DPI via OpenRazer
• Wayland Compatible: Uses evdev/uinput for reliable input remapping under Wayland and X11

Requirements

• Python 3.10+
• OpenRazer daemon (for lighting/DPI control)
• Linux with evdev and uinput support
• PySide6 (for GUI)

Installation

1. Install OpenRazer

# Ubuntu/Debian
sudo add-apt-repository ppa:openrazer/stable
sudo apt update
sudo apt install openrazer-daemon openrazer-driver-dkms

# Add yourself to the plugdev group
sudo gpasswd -a $USER plugdev

2. Install Razer Control Center

cd ~/projects/Razer_Controls
./install.sh

The install script will:

• Create a Python virtual environment
• Install all dependencies
• Set up the systemd user service
• Configure permissions

3. Start the Application

# Start the GUI
razer-control-center

# Or start just the remap daemon
systemctl --user start razer-remap-daemon

Usage

GUI Overview

1. Profiles Panel (left): Create, select, and manage profiles
2. Devices Tab: Select which input devices to remap
3. Bindings Tab: Configure key/button bindings and macros
4. Lighting & DPI Tab: Control OpenRazer device settings
5. Daemon Tab: Start/stop the remap daemon service

Creating a Binding

1. Select a profile (or create a new one)
2. Go to the Bindings tab
3. Click "Add Binding"
4. Select the input key/button (e.g., BTN_SIDE for mouse side button)
5. Choose an action type:
   • Key: Output a different key
   • Chord: Output multiple keys pressed together
   • Macro: Execute a macro sequence
   • Passthrough: Pass the original key through
   • Disabled: Block the key entirely

Creating a Macro

1. Go to the Macros sub-tab in Bindings
2. Click "Add Macro"
3. Enter macro steps in the format:
   • key:A - Press and release A
   • down:CTRL - Hold Ctrl
   • up:CTRL - Release Ctrl
   • delay:100 - Wait 100ms
   • text:hello - Type "hello"

Automatic Profile Switching (App Watcher)

The app watcher automatically switches profiles when you focus different applications.

1. Add match_process_names to your profile JSON:

   {
     "name": "Gaming",
     "match_process_names": ["steam", "*.exe", "lutris", "wine*"],
     "is_default": false
   }
   

2. Set one profile as default (fallback when no match):

   {
     "name": "Default",
     "is_default": true
   }
   

3. Start the daemon with app watcher enabled:

   razer-remap-daemon --app-watcher
   

Pattern matching supports:

• Exact match: firefox
• Wildcards: *.exe, steam*
• Substring: chrome matches com.google.chrome
• Case-insensitive: Firefox matches firefox

Supported backends:

• X11 (requires xdotool)
• GNOME Wayland (uses DBus)

Configuration

Profiles are stored in ~/.config/razer-control-center/profiles/ as JSON files.

Troubleshooting

"Permission denied" when grabbing devices

Add yourself to the input group:

sudo usermod -aG input $USER

Then log out and back in.

uinput not available

Load the uinput kernel module:

sudo modprobe uinput

To load automatically on boot, add to /etc/modules-load.d/uinput.conf:

uinput

OpenRazer not detecting devices

Make sure the OpenRazer daemon is running:

systemctl --user status openrazer-daemon
