There is currently no official driver for the Razer gaming mice in Linux. However, Michael Buesch has created a tool to configure varios Razer mice under Linux. Currently it lists Razer DeathAdder and Razer Krait as Stable, Razer Lachesis as experimental/missing features, Razer Copperhead and Razer Boomslang as not supported.
Getting the tool working under Arch Linux
While there are instructions in the README, I had to modify various things to get the driver to work properly. I am using the Razer Lachesis in my example.
Download the tool from the the author's website. The current latest version is 0.06.
You need to install a few packages prior to this one.
# pacman -S cmake qt4 python python-qt4 libusb
Compiling and installing
Extract the package then then compile and install it there following way:
$ cmake . $ make # make install # ldconfig
Then, copy the daemon:
# cp razerd.initscript /etc/rd.d/razerd
Before your restart
Before you restart, you need to edit your 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" EndSection
It is important to only have "Mouse" and not "Mouse#" listed in xorg.conf.
Next, you need to copy the library as the installer puts it where Arch cannot find it. I simply did:
# cp /usr/local/lib/librazer.so /usr/lib/librazer.so
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
The tool is located under /usr/local/bin/razercfg and /usr/local/bin/qrazercfg. The second one is the GUI one. You can make a shortcut for it and put a fancy icon.
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.
