## Xorg
* The Mali T860MP4 GPU is not supported at this time. Therefore, no particular Xorg drivers are needed. The built in modesetting driver will correctly detect the display.
* xf86-input-libinput is preferred over evdev and synaptics for the best experience with the touchpad and touchscreen.
## Audio
Use `alsaucm` (part of the alsa-utils package) to set up the sound card:
```
ALSA_CONFIG_UCM=/opt/alsa/ucm alsaucm -c rk3399-gru-sound set _verb HiFi
```
Note that the port will display as "Headphones" despite using the speakers. When paired with pulseaudio and pulseaudio-alsa, be aware that the full volume range is addressed through levels 0-9 of the Master volume control. Levels 10-100 provide no additional gain.
