Reminding you about low battery by flashing the LED
Using the trackpad as a mouse
Custom mappings, map buttons and sticks to whatever mouse, key or joystick action you want

Installing

Dependencies

Python 2.7 or 3.3+ (for Debian/Ubuntu you need to install the python2.7-dev or python3.3-dev package)
python-setuptools
hcitool (usually available in the bluez-utils or equivalent package)

These packages will normally be installed automatically by the setup script, but you may want to use your distro's packages if available:

pyudev 0.16 or higher
python-evdev 0.3.0 or higher

Stable release

Installing the latest release is simple by using pip:

$ sudo pip install ds4drv

Development version

If you want to try out latest development code check out the source from Github and install it with:

$ git clone https://github.com/chrippa/ds4drv.git
$ cd ds4drv
$ sudo python setup.py install

Using

ds4drv has two different modes to find DS4 devices, decide which one to use depending on your use case.

Raw bluetooth mode

Supported protocols: Bluetooth

Unless your system is using BlueZ 5.14 (which was released recently) or higher it is not possible to pair with the DS4. Therefore this workaround exists, which connects directly to the DS4 when it has been started in pairing mode (by holding Share + the PS button until the LED starts blinking rapidly).

This is the default mode when running without any options:

$ ds4drv

Hidraw mode

Supported protocols: Bluetooth and USB

This mode uses the Linux kernel feature hidraw to talk to already existing devices on the system.

$ ds4drv --hidraw

To use the DS4 via bluetooth in this mode you must pair it first. This requires BlueZ 5.14+ as there was a bug preventing pairing in earlier verions. How you actually pair the DS4 with your computer depends on how your system is setup, suggested googling: <distro name> bluetooth pairing

To use the DS4 via USB in this mode, simply connect your DS4 to your computer via a micro USB cable.

Permissions

If you want to use ds4drv as a normal user, you need to make sure ds4drv has permissions to use certain features on your system.

ds4drv uses the kernel module uinput to create input devices in user land and the module hidraw to communicate with DualShock 4 controllers (when using --hidraw), but this usually requires root permissions. You can change the permissions by copying the udev rules file to /etc/udev/rules.d/.

You may have to reload your udev rules after this with:

$ sudo udevadm control --reload-rules
$ sudo udevadm trigger

Configuring

Configuration file

The preferred way of configuring ds4drv is via a config file. Take a look at ds4drv.conf for example usage.

ds4drv will look for the config file in the following paths:

~/.config/ds4drv.conf
/etc/ds4drv.conf

... or you can specify your own location with --config.

Command line options

You can also configure using command line options, this will set the LED to a bright red:

$ ds4drv --led ff0000

See ds4drv --help for a list of all the options.

Multiple controllers

ds4drv does in theory support multiple controllers (I only have one controller myself, so this is untested). You can give each controller different options like this:

$ ds4drv --led ff0000 --next-controller --led 00ff00

This will set the LED color to red on the first controller connected and green on the second.

Known issues/limitations

Bluetooth 2.0 dongles are known to have issues, 2.1+ is recommended.
The controller will never be shut off, you need to do this manually by holding the PS button until the controller shuts off
No rumble support

Troubleshooting

Check here for frequently encountered issues.

Failed to create input device: "/dev/uinput" cannot be opened for writing

This could be because the uinput kernel module is not running on your computer. Doing lsmod | grep uinput should show if the module is loaded. If it is blank, run sudo modprobe uinput to load it. (The uinput module needs to be installed first. Please check with your distro's package manager.)

To have the uinput module load on startup, you can add a file to /etc/modules-load.d. For example:

# in file /etc/modules-load.d/uinput.conf
# Load uinput module at boot
uinput
