Razer peripherals

From ArchWiki


Note This page refers to Razer's mice and keyboards. If you were looking for the laptop, see Razer Blade.

Razer Inc makes gaming-focused computer hardware and other consumer electronics. There are currently no official drivers for any Razer peripherals in Linux.

Projects like razercfg, OpenRazer can be used to enable Razer support.

There is also the OpenRGB project which aims to have manufacturer agnostic lighting configurations.

OpenRGB

See OpenRGB.

razercfg

Compatibility

A list of compatible devices can be found here.

Installation

Install the razercfgAUR package.

Enable and start the razerd service.

Tip The package installs udev rules, it is advised to reload them after installation or to reboot.

Configuration

The file /etc/razer.conf can be used to specify various razerd options and initial hardware configuration settings. An example config file is included as razer.conf in the package.

If no configuration file is available, razerd will work with default settings.

Note On X11, you may also need to edit your /etc/X11/xorg.conf file to disable the current mouse settings by commenting them out as in the following example, where also some defaults are set as suggested by the author: 
/etc/X11/xorg.conf
 Section "InputDevice"
    Identifier  "Mouse"
    Driver  "mouse"
    Option  "Device" "/dev/input/mice"
 EndSection
It is important to only have Mouse and not Mouse# listed in xorg.conf.

Using the Razer Configuration Tool

There are two tools provided, one CLI: razercfg and a Qt-based GUI: qrazercfg.

With either tool you can set 5 profiles, change the DPI, change mouse frequency, enable and disable the scroll and logo lights and configure the buttons.

If settings change on reboot, edit the configuration file directly and test after a reload of the service is done. For example: 

/etc/razer.conf
# Configure LEDs
led=1:GlowingLogo:on
led=1:Scrollwheel:on
mode=1:Scrollwheel:static
color=1:Scrollwheel:0000FF
mode=1:GlowingLogo:static
color=1:GlowingLogo:FFFFFF

OpenRazer

Compatibility

A list of compatible devices can be found here.

Installation

Install the openrazer-daemon package. Add your current user to the user group openrazer before logging out and back in.

If customizing and configuring devices is not the priority, one can install just the openrazer-driver-dkms package instead.

How to use

CLI

The razer-cliAUR can be used to configure devices via the terminal.

GUI

The recommended way is to use a graphical front-end for interfacing with the drivers.

Troubleshooting

Visit the Troubleshooting page in the OpenRazer wiki.

Razer keyboards

There are currently two Python scripts available to enable the extra M1 - M5 macro keys, that certain Razers have, under Linux: Note that this does not allow to assign any content to Macro keys, it merely will enable the sending of keycodes. For Razers without M1 -M5 extra keys there is no point using this tool.

Blackwidow Control

Features

  • confirmed to work with regular BlackWidow, BlackWidow 2013 and BlackWidow Ultimate Stealth 2014
  • should also work with BlackWidow Ultimate, BlackWidow Ultimate 2013 and BlackWidow 2014
  • does not work with BlackWidow (Ultimate) 2016 yet
  • uses Python 3
  • allows to control the status of the LED
  • contains a file with udev rule so macro keys will be enabled automatically when the keyboard is plugged in

How to Use

Install blackwidowcontrolAUR. After install, run: 

# blackwidowcontrol -i

Then use the shortcut utility of your Desktop Environment to map the keys, i.e. to actually use the macro keys for something useful. For example, the "KDE global shortcuts" GUI (find it in system settings) can assign macros to a key on any keyboard, not just Razers.

Blackwidow macro scripts

Features

  • Works with BlackWidow Ultimate and Stealth 2013 (unknown whether it works with other versions or keyboard models)
  • adding the "021e" ID for Ornata Chroma makes the Game-mode feature (white "G" LED) work on Ornata Chroma as well.
  • Uses Python 2
  • Bundles scripts to create and execute macros

Troubleshooting

Mouse randomly stops working

Note This is tested on ASUS N550JV using mouse Razer Orochi 2013. Laptop probably has faulty charging port and therefore it sometimes directly affects connected mouse USB port and causes similar issues.

If your razer mouse stops working after some time, however, led flashes or lights up, but reboot and re-plugging does not help, try the following commands.

Unload ehci_pci and ehci_hcd modules: 

# rmmod ehci_pci
# rmmod ehci_hcd

Disconnect the mouse, wait a few seconds and run the following commands to load modules back: 

# modprobe ehci_hcd
# modprobe ehci_pci

Connect the mouse and it should be working.

CAPS Lock makes Razer Blade Stealth crash

The crash is caused by keyboard built-in driver.

If using Xorg

Get the keyboard description: 

$ xinput list | grep "Set 2 keyboard"

And create the file below, here we assume the above command returned "AT Raw Set 2 keyboard". 

/etc/X11/xorg.conf.d/00-keyboard-razer.conf
Section "InputClass"
    Identifier      "Disable built-in keyboard"
    MatchProduct    "AT Raw Set 2 keyboard"
    Option          "Ignore"    "true"
EndSection

If using Xwayland

/etc/default/keyboard
XKBOPTIONS="ctrl:nocaps"

CAPS Lock will now be identified as another CTRL key.
