Are you facing an error while launching Chrome on WSL Ubuntu? The error message might say "Failed to connect to the bus, Missing X server or DISPLAY." Don't worry, we've got you covered! In this article, we will explain what this error means and provide you with step-by-step solutions to fix it.
Understanding the Error
Before we dive into the solutions, let's understand what this error actually means. When you try to launch Chrome on WSL Ubuntu, it requires access to the X server, which handles the graphical user interface. The error message indicates that Chrome is unable to connect to the X server or that the X server is missing.
Possible Causes
There are a few possible causes for this error:
- The X server is not installed on your system.
- The X server is not running.
- The DISPLAY environment variable is not set correctly.
Solutions
1. Install X server
If you haven't installed the X server on your WSL Ubuntu system, you need to install it first. Open your terminal and run the following command:
sudo apt-get install xorg
This command will install the X server and its dependencies on your system. Once the installation is complete, proceed to the next solution.
2. Start X server
If the X server is not running, you need to start it manually. Open your terminal and run the following command:
sudo service xorg start
This command will start the X server on your system. Once the X server is running, try launching Chrome again and see if the error persists.
3. Set the DISPLAY environment variable
The DISPLAY environment variable tells applications where to display their graphical output. If the DISPLAY variable is not set correctly, Chrome won't be able to connect to the X server. To set the DISPLAY variable, open your terminal and run the following command:
export DISPLAY=:0
This command sets the DISPLAY variable to the default value of ":0". Now, try launching Chrome again and see if the error is resolved.
Conclusion
In this article, we discussed the error "Failed to connect to the bus, Missing X server or DISPLAY" that occurs when launching Chrome on WSL Ubuntu. We explored the possible causes of this error and provided you with step-by-step solutions to fix it. By installing the X server, starting it if necessary, and setting the DISPLAY environment variable correctly, you should be able to launch Chrome without any issues.
