# Razer

This article or section needs language, wiki syntax or style improvements.

Reason: Various style issues, structure lacking (Discuss in Talk:Razer#)

There are currently no official drivers for any Razer peripherals in Linux. However, Michael Buesch has created a tool called razercfg to configure Razer mice under Linux. There also exist scripts to enable macro keys of Razer keyboards. A relatively new package, razer-driver-metaAUR can be used to enable Razer support. Supported devices are listed here

## Razer Peripherals

### Compatibility

razercfg lists the following mice models as stable:

- Razer DeathAdder Classic
- Razer DeathAdder 3500 DPI
- Razer DeathAdder Black Edition
- Razer DeathAdder 2013
- Razer DeathAdder Chroma
- Razer Krait
- Razer Naga Classic
- Razer Naga 2012
- Razer Naga 2014
- Razer Naga Hex
- Razer Taipan

And the following as stable but missing minor features:

- Razer Lachesis
- Razer Copperhead
- Razer Boomslang CE

### Installation

Download and install razercfgAUR or razercfg-gitAUR for bleeding edge git releases from the AUR.

You 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`.

The factual accuracy of this article or section is disputed.

Reason: Why reboot? (Discuss in Talk:Razer#)

Restart the computer, then enter:

    # udevadm control --reload-rules

Then start the `razerd` daemon and possibly enable it.

### Using the Razer Configuration Tool

The factual accuracy of this article or section is disputed.

Reason: Button configuration reported to not work (Discuss in Talk:Razer#Button configuration in razercfg or qrazercfg)

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.

If the colors reset on reboot edit the config file directly and test with another reboot:

    /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

"static" can probably be changed to spectrum or breathing, and mode/color lines can be removed if led is set to "off".

## Razer Blade

Razer Blade is Razer's line of gaming laptops. There is currently a 14" model, and a 17" model. Due to the proprietary SBUI trackpad on the 17" model, it will be extremely difficult to get it to work without extensive USB protocol reversing.

### 2016 version (Razer Blade & Razer Blade Stealth)

The normal installation process works in general with the exceptions enumerated below.

#### Killer Wireless Network Adapter

Killer Wireless adapters no longer require special firmware to function, and will work right out of the box.

#### Touchpad

Install the xf86-input-libinput package. See Libinput for more information on this driver.

Alternatively, if you prefer using the Touchpad Synaptics driver, install the xf86-input-synaptics package.

#### Touchscreen

While the touchscreen will provide basic functionality out of the box, it is best to use toucheggAUR to configure multitouch gestures. These include two-finger scrolling, right-click, etc.

#### Graphics Drivers

The graphics card works OK with the standard intel drivers which you can install with the xf86-video-intel package. See Intel graphics for more information on installation and configuration.

Issues with screen flickering seem to be resolved by changing AccelMethod to uxa as described in the SNA issues section.

    # cat >/etc/X11/xorg.conf.d/20-intel.conf
    Section "Device"
      Identifier  "Intel Graphics"
      Driver      "intel"
      Option      "AccelMethod"  "uxa"
      #Option      "AccelMethod"  "sna"
    EndSection

#### Hybrid graphics

If the discrete Nvidia GPU is switched off before starting Xorg or Wayland, then the system freezes. The only possible solution is to manually disable/enable the discrete card after starting the graphical session. However there is a ACPI DSDT fix available which fixes this problem. Check the repository for more information.

#### Suspend Loop

Suspending (Close laptop lid) does not seem to work with a basic installation. There is a bug in the linux kernel which causes the ACPI "lid open" event to be dropped and not modify the stored state of the lid switch. Since systemd monitors the lid switch state, it will eventually check and see that it is "closed" and resuspend the laptop. The correct fix is to not drop the ACPI event in the kernel, but for now a workaround is possible.

The only known workaround until the kernel is fixed, is to disable the automatic systemd suspend action by changing the HandleLidSwitch value in the /etc/systemd/logind.conf file:

    HandleLidSwitch=ignore

After this, install pm-utils and acpid, use systemctl to enable acpid at boot, and create a file named /etc/acpi/events/lid with the following contents:

    event=button/lid
    action=/usr/bin/pm-suspend

#### Tweaking

If you are using GNOME, the gnome-tweak-tool can be used to adjust the window and font scaling. A font scale of 1.25 puts the font sizes closer to how they are displayed by default in Windows 10.

If you are using an external monitor that is not HiDPI, you can use xrandr to alter the scaling of the external monitor using the instructions for Multiple Displays. You may have better results though running GNOME on Wayland. When installed, clicking the gear icon in GDM will allow you to select Gnome On Wayland and will default to that in the future.

#### Unresolved Issues

- the webcam does not seem to work well with a basic installation. External webcams work fine. It seems to fail when the resolution is anything but 640x480. guvcview works because it defaults to the resolution. cheese and Google Hangouts do not because they default to the max resolution. your mileage may vary.

### 2014 version

#### Problems

Source

- touchpad (multitouch, although this may be a kernel bug that has since been fixed)
- keys to increase/decrease screen illumination not working
- keys to increase/decrease keyboard illumination not working

#### Possible trackpad solution

Source

    git clone https://github.com/aduggan/hid-rmi.git -b rb14 # and then install it
    depmod -a

Then install the synaptics[broken link: replaced by xf86-input-synaptics] package.

Feature still not working: pinch to zoom, 3rd mouse button.

### 2013 version

#### What works

Source

- Wireless
- Switchable graphics
- Bluetooth
- Keyboard light (HW controlled)
- UEFI boot
- Trackpad (only on Linux 4.0+ without libinput-based X.Org input driver (xf86-input-libinput) thanks to Andrew Duggan's work).

#### Problems

Source

- SwitchBlade UI doesn't work due to lack of drivers.
- Trackpad scrolling does not work.

#### Possible trackpad solution

Source

    git clone https://github.com/aduggan/hid-rmi.git -b rb14 # and then install it
    depmod -a

Then install the synaptics[broken link: replaced by xf86-input-synaptics] packages.

Feature still not working: pinch to zoom, 3rd mouse button

Reason: The SBUI works as a trackpad, but no linux drivers currently exist. Does it even work for basic trackpad functionality? (Discuss in Talk:Razer#)

## Razer keyboards

There are currently two Python scripts available to enable macro keys under Linux:

### 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 it from AUR blackwidowcontrolAUR After install run as root

    $ blackwidowcontrol -i

Then use the shortcut utility of your Desktop Enviroment to map the keys

### Blackwidow macro scripts

#### Features

- Works with BlackWidow Ultimate 2013 (unknown whether it works with other versions)
- 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.
