# Enhance your WSL 2 experience with Xfce4

# Introduction

In this article, I want to talk about enhancing your WSL 2 experience by installing `Xfce4` as the Desktop Environment where you can remote into using `Windows Remote Desktop Connection`

This is especially useful if you are still not quite used to using just command-line or you prefer using GUI to navigate around the OS

# What is WSL 2?

Quote directly from [microsoft](https://docs.microsoft.com/en-us/windows/wsl/compare-versions)

> WSL 2 uses the latest and greatest in virtualization technology to run a Linux kernel inside of a lightweight utility virtual machine (VM). However, WSL 2 is not a traditional VM experience

In my opinion, it improves the developer experience without the need to dual boot or runs a separate Linux VM to experience the native Linux user experience, and improve the quality of a developer life

# Installation

> Minimally, you need to be running Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11

- Launch your terminal
- Run `wsl --install`
  - `Ubuntu` is the default distribution
  - You are free to choose any other  [distribution](#distribution) to your liking
  - It should take a little while to install
- Once installed, it will prompt you to setup your `username` and `password`
- Once done, it will be ready to use

If you are curious, the installed path would be at `%UserProfile%\AppData\Local\Packages\`

For `Ubuntu`, the actual path would be `%UserProfile%\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc` but for other distribution such as `Kali-Linux`, it would be `%UserProfile%\AppData\Local\Packages\KaliLinux.54290C8133FEE_ey8k8hqnwqnmg`

## Ensure distribution running on WSL 2

> If you have installed via `wsl --install` command, by default, it should already be using version 2

After the installation is completed, let's confirm that we are using `version 2` and not `version 1`

- Launch your terminal
- Run `wsl -l -v`
  - `-l` refers to `list` for listing all existing distributions
  - `-v` refers to `verbose` where it displays detailed information regarding the distribution such as the version
 
> Run `wsl -help` to view all command options


![wsl-2-l-v.gif](https://cdn.hashnode.com/res/hashnode/image/upload/v1644061252871/gnQY2bjP_.gif)

```bash
❯ wsl -l -v
NAME                   STATE           VERSION
* Ubuntu                 Running         2
```

- This shows us that we are running on `Ubuntu` distribution and am indeed on `version 2`
- If you are on version 1, then you should convert to `version 2` by running `wsl --set-version Ubuntu 2`
  - This will start the process to convert from `version 1` to `version 2`
  - It will take a short while to perform the conversion

> WSL default version can be set to version 2 by running `wsl --set-default-version 2`

Based on my understanding, the difference between `version 1` and `version 2` in terms of installation is that for `version 1`, it would have stored all the files in `%installed_directory%\rootfs` whereas for `version 2`, it stores all the files in `%installed_directory%\ext4.vhdx` which is a `virtual drive` 

## Set default distribution

### Distribution

There are a few distributions for us to install if you do not want to use `Ubuntu`

- Run `wsl -l -o` to view the available distribution
  - `-l` refers to `list` for listing all existing distributions
  - `-o` refers to `online` where it displays list of available distributions for install

![wsl-2-l-o.gif](https://cdn.hashnode.com/res/hashnode/image/upload/v1644061371744/ZXqsTxgqb.gif)

```bash
❯ wsl -l -o
The following is a list of valid distributions that can be installed.
Install using 'wsl --install -d <Distro>'.

NAME            FRIENDLY NAME
Ubuntu          Ubuntu
Debian          Debian GNU/Linux
kali-linux      Kali Linux Rolling
openSUSE-42     openSUSE Leap 42
SLES-12         SUSE Linux Enterprise Server v12
Ubuntu-16.04    Ubuntu 16.04 LTS
Ubuntu-18.04    Ubuntu 18.04 LTS
Ubuntu-20.04    Ubuntu 20.04 LTS
```

If you have a number of installed distributions installed on your machine, you can set the default distribution by running `wsl --setdefault <distribution>`

```bash
> wsl --setdefault Ubuntu
```

  - this is so that when we type `wsl`, it will know to launch the correct distribution
  - the `*` beside the distribution name indicates the default distribution

> [Oracle Linux 8.5](https://www.microsoft.com/en-sg/p/oracle-linux-85/9p06h18wxbvp?activetab=pivot:overviewtab) has recently landed as one of the newer distributions as well

# Installing Xfce4

Now that you have set up and installed your favorite Linux distribution on your machine, where you can access it via the terminal. What's next? You can improve then your experience by navigating the OS using GUI (Desktop Environment)

[Xfce](https://xfce.org/) is a lightweight desktop environment for UNIX-like operating systems. It aims to be fast and low on system resources, while still being visually appealing and user friendly


> The installation will take up around 2-3gb of disk space and some time to finish, please be patient

- Launch your terminal
- Run `wsl`
  - This will get you into the `Ubuntu` shell
  - Input user credential as prompted (if required)
- Run the following commands one by one

![wsl-xfce4.gif](https://cdn.hashnode.com/res/hashnode/image/upload/v1644076972246/pBOmDKvAd.gif)

> I skipped a portion of the gif to remove the waiting time (total duration is 1:29 seconds)

```bash
> wsl

sudo apt update -y && sudo apt upgrade -y
sudo apt install xfce4 -y [1]
sudo apt install xrdp -y [2]
echo xfce4-session > ~/.xsession [3]
sudo service xrdp restart
sudo apt install net-tools -y [4]
ifconfig | grep inet
```

1. Choose `gdm3` when prompted during the installation
2. [xrdp](http://xrdp.org/) allows us to `RDP` into the distro from `Windows RDP`
2. Without this, you might get disconnected immediately after connecting via `RDP` 
3. Running `ifconfig | grep inet` will display the ip address to remote in

```bash
inet 172.23.201.70 netmask 255.255.240.0  broadcast 172.23.207.255
inet6 fe80::215:5dff:fe74:4236  prefixlen 64  scopeid 0x20<link>
inet 127.0.0.1  netmask 255.0.0.0
inet6 ::1  prefixlen 128  scopeid 0x10<host>
```

> Take note of the inet address

## Access using Windows RDP

Once installed, it is now to try to access via `Windows Remote Desktop Connection`

- Launch `Search bar`
- Type `remote desktop connection`
- Input the `ip` and click `connect`

![windows-rdp.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1643965671666/ne3eaWzQz.png)

- Once connected, proceed to input your credentials

![linux-xrdp.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1643965795792/WQXRNtuLf.png)

- And you have a fully functional Desktop Environment

![ubuntu-desktop.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1643965861383/gCXqa0yam.png)

- You will be able to browse to your host OS using the explorer as usual

# Alternative to Xfce4?

## XUbuntu

The instruction to install [XUbuntu](https://xubuntu.org/) would mostly be the same as installing `Xfce4` except to run this for the first command. `XUbuntu` also comes with `Xfce` but provide a richer experience compared to `Xfce`

```bash
sudo apt install xubuntu-desktop -y
// the rest of the commands will be the same as installing Xfce4
```

> Note that `xubuntu` takes up around 5-6gb of disk space

## GWSL

Well, it's not exactly an alternative per se because of how it works. But end state is that you will be interacting in a graphical mode rather than command line

So if you would rather run the apps on your Windows OS instead of remote into the Linux distribution, then you can try [GWSL](https://opticos.github.io/gwsl/). It lets you run graphical Linux apps on `Windows 10` directly. It certainly looks pretty damn good to me but I haven't tried it myself. If you do try it, let me know your experience in the comments

I embedded a youtube demo taken from their website

# Conclusion

`WSL` has come a long way from having to download Linux kernel, enable WSL and Virtual Machine Platform feature, set WSL 2 as default version and so on down to just a single command - `wsl --install`

Furthermore, we are still able to navigate and experience the OS through `Xfce4` instead of just on the terminal which is sometimes the preferred way for some users (especially for Windows users)
