Xorg

  • The PowerVR GX6250 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

The following channels must be unmuted for the speakers to work. The alsamixer utility (part of alsa-utils) can be used to do this by navigating with the arrow keys and pressing m to unmute the channel.

  • Speaker Channel
  • DAC MIXL DAC L2
  • DAC MIXL DAC R2
  • DAC MIXL Sto DAC Mix L
  • DAC MIXR DAC L2
  • DAC MIXR DAC R2
  • DAC MIXR Sto DAC Mix R
  • DAC1 MIXL DAC1
  • DAC1 MIXL Stereo ADC
  • DAC1 MIXR DAC1
  • DAC1 MIXR Stereo ADC
  • 003 I05
  • 004 I06
  • SPK MIXL DAC L1
  • SPK MIXR DAC R1
  • SPKVOL L
  • SPKVOL R
  • SPOL MIX DAC L1
  • SPOL MIX DAC R1
  • SPOL MIX SPKVOL L
  • SPOL MIX SPKVOL R
  • SPOR MIX DAC R1
  • SPOR MIX SPKVOL R

You may also want to decrease the DAC1 gain value, otherwise audio will still be fairly loud at the lowest setting.
