Edge2 Chromium with WebGL

Introduction

This document mainly describes how to install Chromium and add WebGL support.

If you install Chromium using snap, you can't use WebGL.

This is just an experienced function, you may got some issues when you enable the WebGL, you can follow the steps below to enable WebGL at your own risk.

Upgrade the System

You need to upgrade the system to latest version.

sudo apt update
sudo apt full-upgrade
sync
sudo reboot

Adjust GPU Links

In order to use the WebGL you need to adjust the GPU links, you can follow the steps below:

sudo cp /usr/lib/aarch64-linux-gnu/libgbm.so.1.0.0 /usr/lib/aarch64-linux-gnu/libgbm.so.1.0.0.backup
sudo ln -fs /usr/lib/aarch64-linux-gnu/libMali.so /usr/lib/aarch64-linux-gnu/libgbm.so.1.0.0
sync

These steps will break the X11 desktop, if you want to use the X11 desktop, you can follow the tetps below to recovery to original state.

sudo rm /usr/lib/aarch64-linux-gnu/libgbm.so.1.0.0
sudo mv /usr/lib/aarch64-linux-gnu/libgbm.so.1.0.0.backup /usr/lib/aarch64-linux-gnu/libgbm.so.1.0.0
sync

Install Chromium from APT Source

Ubuntu 22.04 will use snap to install software by default, in order to add WebGL support we need to install Chromium from other apt source.
