• Net-install of KDE Neon on WSL1 using xRDP. If you prefer GTK, see xWSL or Kali-xRDP
• Runs on Windows 10 and Server 2019/2022 (including Hyper-V Core)
• xRDP Display Server; no additional Xserver download/configuration required
• High-quality RDP audio playback; video playback and YouTube work well and maintains audio sync.
• If you want to accesss kWSL remotely, Chrome Remote Desktop is pre-installed (Never expose RDP servers to the Internet.) Configuration steps are here

IMPORTANT!

• Windows 11 requires 22H2 Update (Sun Valley 2, September 2022)
• Windows Server / Windows 10 require latest updates from Windows Update.

From an elevated CMD.EXE prompt change to your desired install directory and type/paste the following command:

PowerShell -executionpolicy bypass -command "wget https://github.com/DesktopECHO/kWSL/raw/master/kWSL.cmd -UseBasicParsing -OutFile kWSL.cmd ; .\kWSL.cmd"

You will be asked a few questions. The install script will determine current DPI scaling, or set your own value if preferred:

[kWSL Installer 20210609]

Enter a unique name for your kWSL distro or hit Enter to use default.
Keep this name simple, no space or underscore characters [kWSL]: Neon
Port number for xRDP traffic or hit Enter to use default [3399]: 13399
Port number for SSHd traffic or hit Enter to use default [3322]: 13322
Set a custom DPI scale, or hit Enter for Windows default [1.5]: 1.25
[Not recommended!] Type X to eXclude from Windows Defender:

Installing kWSL Distro [Neon] to "C:\WSL Distros\Neon"
This will take a few minutes, please wait...

The installer will download all the necessary packages to transform the Focal base image into KDE Neon User Edition. Reference times will vary depending on system performance and the presence of antivrirus software. A fast system/network can complete the install in about 10 minutes.

Near the end of the script you will be prompted to create a non-root user. This user will be automatically added to sudo'ers.

  - xRDP Server listening on port 13399 and SSHd on port 13322.

  - Links for GUI and Console sessions have been placed on your desktop.

  - (Re)launch init from the Task Scheduler or by running the following command:
    schtasks /run /tn Neon

 Neon Installation Complete!  GUI will start in a few seconds...

When the script completes you will be logged-in to your KDE Neon Desktop.

• Right-click the task in Task Scheduler, click properties
• Click the checkbox for Run whether user is logged on or not and click OK
• Enter your Windows credentials when prompted

Reboot your PC when complete and kWSL will startup automatically.

Example of conversion to WSL2:

• Stop WSL instance (Using default instance name NeonWSL in this example): wslconfig /t NeonWSL
• Convert the instance to WSL2: wsl --set-version NeonWSL 2
• Restart KDE Neon Instance: schtasks /run /tn NeonWSL

Restart the instance when the conversion is complete: schtasks.exe /run /tn NeonWSL

Procedure is the same for switching back to WSL1: wsl --set-version NeonWSL 1

From a security standpoint, it would be best to fork this project so you (and only you) control the packages and files in the repository.

• Sign into GitHub and fork this project
• Edit kWSL.cmd. On line 2 you will see SET GITORG=DesktopECHO - Change DesktopECHO to the name of your own repository.
• Customize the script any way you like.
• Launch the script using your repository name: PowerShell -executionpolicy bypass -command "wget https://github.com/YOUR-REPO-NAME/kWSL/raw/master/kWSL.cmd -UseBasicParsing -OutFile kWSL.cmd ; .\kWSL.cmd"

• When you log out out of a KDE session the WSL instance is restarted. This is the equivilent to having a freshly-booted desktop environment at every login, but the 'reboot' process only takes about 5 seconds.
• kWSL should work fine with an X Server instead of xRDP but this has not been thoroughly tested. The file /etc/profile.d/kWSL.sh contains WSL-centric environment variables that may need adjustment such as LIBGL_ALWAYS_INDIRECT.
• Plasma-discover doesn't work in Server 2019 / Win 10 v.1809 -- The installer will remove it if you're running an affected OS.
• WSL1 Doesn't work with PolicyKit. Enabled kdesu for apps needing elevated rights (plasma-discover, ksystemlog, muon, root console.)
• KDE Lockscreen is disabled (due to policykit)
• Patched KDE Activity Manager to disable WAL in sqlite3.
• Mozilla Seamonkey is included as a stable/maintained browser.
• QtWebEngine (Chromium-based) browsers like Falkon and Konqueror now work. (July/21)
• Installed image consumes approximately 3 GB of disk space.
• Apt-fast added to improve download speed and reliability.
• Default installation uses the Breeze theme and Windows fonts (Segoe UI / Cascadia Code)
• Compositor replaced with Picom for better RDP performance and includes the Klassy window decoration / application style plugin
• This is a basic installation of KDE to save bandwidth. If you want the complete KDE Desktop environment (+3GB Disk) run sudo pkcon -y install neon-all
