Installation

Warning
Installing the operating system on this Chromebook requires flashing the UEFI firmware.

Gentoo LiveGUI USB Image

Sound

Warning
The following script automatically re-logins the user, causing running applications to stop working. Save any changes before running the script to prevent data loss.
Important
The script requires root privileges.

By default, the sound card is disabled, there is no output to the speakers and there is no way to connect a Bluetooth headset. The image does not contain required firmware blobs, so it is necessary to install them. The following script installs the blobs and configures PipeWire to use the sound card.

Note
The accelerometer can be tested by running the following command:

Configuration

Sound

Important
The user must belong to the audio and pipewire groups, otherwise the daemon will not connect to the sink.

Install media-video/pipewire with the following USE flags: sound-server, pipewire-alsa, bluetooth (optional).

The sound doesn't work out of the box, so you have to manually specify the sink and source. In the case of Bluetooth or 3.5mm jack, no additional configuration is required.

FILE /etc/pipewire/pipewire.conf.d/alsa.conf
context.objects = [
  { factory = adapter
    args = {
      factory.name	= api.alsa.pcm.sink
      node.name		= "alsa-sink"
      node.description	= "PCM Sink"
      media.class	= "Audio/Sink"
      api.alsa.path	= "hw:0,5"
    }
  }

  { factory = adapter
    args = {
      factory.name	= api.alsa.pcm.source
      node.name		= "alsa-source"
      node.description	= "PCM Source"
      media.class	= "Audio/Source"
      api.alsa.path	= "plughw:0,1"
    }
  }
