There is currently no official driver for the Razer gaming mice in Linux. However, Michael Buesch has created a tool called razercfg to configure Razer mice under Linux.


razercfg lists the following mice models as stable:

  • Razer DeathAdder Classic
  • Razer DeathAdder 3500 DPI
  • Razer DeathAdder Black Edition
  • Razer Krait
  • Razer Naga

and the following as stable but missing minor features:

  • Razer Lachesis
  • Razer Copperhead
  • Razer Boomslang CE


The tool can simply be downloaded and installed from the AUR here; or you may wish to download the git version for bleeding-edge releases.

After installing with pacman you need to add the razerd daemon to the DAEMONS array in /etc/rc.conf

You also need to edit your /etc/xorg.conf file to disable the current mouse settings. I just commented them out then set some defaults as suggested by the author:

 Section "InputDevice"
    Identifier  "Mouse"
    Driver  "mouse"
    Option  "Device" "/dev/input/mice"

It is important to only have Mouse and not Mouse# listed in xorg.conf.

For Python 3 users

If you have python 3 set as your default version then you will have to make a simple change to the source code of the two utilities. You can check by typing the following command
$ python -V
If it returns python 2.X then you can skip this section. If it returns python 3.X then change the first line of both files /usr/bin/razercfg and /usr/bin/qrazercfg to the following:
#!/usr/bin/env python2

Final touches

Retart the computer then enter:

# udevadm control --reload-rules

To start the daemon, type:

# /etc/rc.d/razerd start

If you did everything correctly, you shouldn't get errors.

Using the Razer Configuration Tool

There are two commands you can use, one for the command line tool razercfg or the Qt-based GUI tool qrazercfg.

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


Everytime I restart, my Razer Lachesis is brought back to 500 DPI. Not that cruicial as I just open the Razer Configuration Tool and set it to 4000 DPI and all is good. I've e-mailed him on this issue and am waiting on a reply.
