This is an install and configuration guide for the Dell Inspiron 3420 laptop, testing with the 2016.09.03 version.

See the Laptop/Dell chart for information on other Dell laptops.

## Audio

There are two options to get audio working: ALSA and PulseAudio. With ALSA the sound works well, both headphone jacks work and volume can be set independently. With Pulse Audio you will generally get better quality and louder sound.

## Video

The notebook comes with the Intel HD 4000 GPU, which uses the xf86-video-intel driver. See Intel for details.

### Toggle between HDMI/Monitor

See xrandr.

## Touchpad

To enable scroll and more, install xf86-input-synaptics. With the default configuration file it will work well, but if you want to fine tune the behavior.

See: Touchpad Synaptics.

This laptop comes Broadcom Corporation BCM43142 wireless card, which requires broadcom-wl-dkms
