Can't open network manager GUI on WSL2 Ubuntu

If you're a Windows user leveraging the Windows Subsystem for Linux (WSL2) and using Ubuntu as your Linux distribution, you may encounter issues with opening the Network Manager GUI. This can be a frustrating barrier when trying to manage your network settings. This article will guide you through understanding the problem, offer practical solutions, and explain why you can't open the Network Manager GUI in WSL2 Ubuntu.

Problem Overview

The original problem states: "Can't open network manager GUI on WSL2 Ubuntu."

This sentence indicates that users are having difficulty accessing the graphical interface for managing network settings in Ubuntu running on WSL2.

Why the Issue Arises

WSL2 provides a compatibility layer for running Linux binaries on Windows. However, it does not support running GUI applications in the same way a standard Linux installation does. As a result, when you try to open the Network Manager GUI, you might find it unresponsive or not available. The Network Manager GUI is designed to provide an easy interface for managing network connections and configurations, which can be particularly useful for users who prefer not to rely solely on command-line instructions.

Potential Solutions

  1. Use Command-Line Tools Instead

    • While it’s more convenient to use GUI applications, many tasks can be performed using command-line tools in WSL2. To manage network configurations, you can use commands like nmcli, which is the command-line interface for NetworkManager.
    • Example usage:
      nmcli device
      nmcli connection show
      
  2. Install a X Server on Windows

    • If you specifically want to run the Network Manager GUI, you can install an X Server on Windows, like VcXsrv or Xming. After installation, start the X server and set the display environment variable in your WSL2 terminal.
    • Example:
      export DISPLAY=$(ipconfig | grep "IPv4" | awk '{print $NF}'):0.0
      
    • After setting this, you should be able to run graphical applications, though the performance may vary.
  3. Use an Alternative Configuration Tool

    • Consider using other configuration tools that may offer GUI capabilities on Windows but are also able to interact with WSL2. Tools like PuTTY for SSH access might also provide some level of network management functionality depending on your needs.

Additional Explanations and Examples

To understand why WSL2 does not support GUI applications natively, it's essential to recognize that WSL2 is designed primarily to run Linux command-line tools and applications. However, Microsoft has made strides toward incorporating more Linux-like capabilities, including support for some graphical applications. With the recent updates to WSL, users can explore additional solutions, such as WSLg, which allows for running GUI Linux applications directly on Windows.

An example of using nmcli to create a connection would look like this:

nmcli dev wifi connect "your_wifi_name" password "your_password"

This command connects your WSL2 instance to a Wi-Fi network using NetworkManager's command-line tool.

Conclusion

While opening the Network Manager GUI directly in WSL2 Ubuntu is not possible due to the limitations of WSL, utilizing command-line tools or installing an X server on Windows are viable workarounds. By incorporating these methods, you can efficiently manage your network settings without relying solely on GUI applications.

Useful Resources

By utilizing these resources, you can deepen your understanding of managing network settings in WSL2 and explore other functionalities that Linux can provide within your Windows environment.
