Chrome OS Flex is a new Operating System offered by Google. Chrome OS Flex is a toned-down, and lighter version of Google’s Chrome OS. Just like normal Chrome OS, we can enable Linux on Chrome OS Flex also known as Crostini.
Why Install Linux on Chrome OS Flex?
Chrome OS Linux, sometimes called Crostini, allows you to run Linux applications for development in addition to the regular desktop and Chrome OS applications. Linux on Chrome OS Flex offers developers the best of both worlds.
Built and designed on the principles of simplicity and security of Chrome OS, Linux on Chrome OS Flex gives developers the freedom to run their favorite editors, IDEs, and thousands of world-class development tools safely at once.
Benefits
When Linux is turned on, a terminal is installed that you can use to run command-line tools. You can also install graphics applications, such as Editing and IDEs, that are in the launcher, along with the rest of Chrome OS Flex applications.
Another useful tool, the file application, makes it easy to create a shared folder for transferring files between a Chrome OS Flex host and a Linux container.
Enable Linux on Chrome OS Flex
Once you have installed Chrome OS Flex on your computer. The next thing you need to do to take full advantage of it is to enable the Linux subsystem. We can do that by going into the Settings and then under Advanced options, choose Developers.

Now we can see the option to Turn On Linux from here. We need to give it a custom name and assign a partition space. The minimum space required is 10 GB. But I would recommend at least 15 GB and above. Now we can proceed with the installation.
Getting Started
After it is done installing your device may reboot or you may see the Linux command terminal straight away. The first command we need to run in order to set up everything is:
sudo apt update
sudo apt upgrade
Now after running the above command, we can proceed to install other Linux programs as required. But do remember not all Linux apps will work on Chrome OS Flex. I have tried installing various browsers and they do work. Apps like VLC player, Libre Office, and Zoom does work as well.

sudo apt install (program-name)
sudo apt install libreoffice
Google Play Store Alternative
Installing Linux apps from the terminal is not the easiest way for many. it would be much easier if we had an app store like the Google Play Store to install the apps we like. Fortunately, there is a way from which we can do exactly that.
Open the terminal and run the following commands:
sudo apt install plasma-discover
sudo apt update
sudo apt upgrade
This process does take a long time. In my case, it took more than 20 minutes. But once it is done we can see the Plasma Discover app in the app launcher. We can see a variety of apps listed and we can install them with one click.

I tried installing the Kdenlive Video editor app and it installed and ran successfully. if you face issues with the preview in Kdenlive flickering. Open chrome://flags in the Chrome browser and search for crostini-GPU-support and disable the option.
