How to Enable Microphone and GPU Acceleration in Linux on Chromebook – Guide

While support for Linux on Chromebooks was announced three years ago, meaning running Linux on Chromebooks has been possible for a long time, it initially lacked some basic features. However, Google seems to be catching on up now that it’s at the forefront of making Chrome OS a viable platform for everyone. For example, you can now enable mic and GPU acceleration in Linux on Chromebooks. Both features have been a long-standing demand from creative and power users, and finally, Google has delivered on that promise. So without further ado, let’s go ahead and learn how to enable microphone support and hardware acceleration on Linux on Chrome OS. ..

Chrome OS 81 added GPU acceleration by default. However, some Chromebooks still require an update to the Linux container to use this feature. To use this feature, you must update the Linux container to the latest version of Debian Buster. If you experience problems with hardware acceleration or your Chromebook’s battery drains quickly, it may be because the GPU is not compatible with your device or the driver is not up-to-date.

Enable Microphone Support in Linux on Chromebooks

You can enable the microphone on Chromebooks right now, and for that, you don’t need to upgrade to the Beta or Dev channel. You can enable microphone support on Linux by following these simple steps:

  1. Open a Terminal window and type " echo " > /sys/class/mic/card0/input/microphone ;"
  2. Type " sudo apt-get update " and " sudo apt-get install mic-tools " to update your Debian or Ubuntu system.
  3. Type " sudo nano /etc/default/mic " and change the MIC_HOSTNAME variable to your desired hostname (e.g., mycomputer ).

There, you’ll find a section called “Linux Kernel Parameters.” In this section, you can change the settings of the Linux kernel, which affects how your Chromebook works.

Linux development environment is a software that helps developers create, test and deploy applications on the Linux operating system. ..

To enable Linux to access your microphone, follow these steps:

  1. Open a terminal window and type the following command: sudo allow linux audio
  2. Press Enter to confirm the change and exit the terminal window. ..

Now, open any audio recording application and start recording your voice.

Now, open any audio recording application and start recording your voice.

Enable GPU Acceleration on Linux on Chromebooks

Chromebooks with GPU acceleration by default use the Nvidia Tegra K1 chip. To enable it, you need to update your Linux container to the latest version of Debian Buster. To do this, you can either use a command line tool or a GUI tool. The command line tool is called apt-get and it can be found in the Ubuntu repositories. The GUI tool is called apt-get install nvidia-graphics-driver .

On the Chrome Flags page, you can see how many extensions are installed on your browser.

After that, search for “Crostini GPU Support” and enable it from the drop-down menu. You can also directly open the dedicated flag at the address below. Now, click on the “Restart” button button in the background. After you have enabled Crostini support, restart your computer to apply the changes. ..

To update packages and dependencies on your Linux system, run the following command: sudo apt-get update

sudo apt-get update && sudo apt-get upgrade

After the packages are updated, run the command below to install Mesa. It lets you know whether or not GPU acceleration has been enabled on your Chromebook.

sudo apt-get install mesa-utils -y

Linux Terminal If you see “Accelerated: Yes” in the Linux Terminal, then your Chromebook has been enabled to use GPU acceleration.

Final note

How to Enable Microphone and GPU Acceleration in Linux on Chromebook This guide will show you how to enable microphone and graphics acceleration in Linux on a Chromebook. This will allow you to run more demanding games and applications with better performance. First, we need to install the necessary software. You can find the list of software here. Once you have installed the software, open a terminal and type this command: sudo apt-get update sudo apt-get install linux-headers-3.10 linux-headers-3.11 linux-graphics-3.10 linux-graphics-3.11 Now we need to create a file called “config” in our home directory: touch config && nano config Now, add the following lines into our config file: # microsoftwindows 10 support # Enable microphone for Windows 10 users # Uncomment if you want to use Nvidia’s Geforce Graphics card as well # Add your name (or your company’s name) if you want to be contacted by us during support issues! mic=1 gpu=0 # Add your address (or your city) if you want to be contacted by us during support issues! address=1
