I am following the beginner rosnode tutorial

The environment is Windows 10 / WSL. When I enter command rosrun turtlesim turtlesim_node after running "roscore", I get the following error:

wn-003% rosrun turtlesim turtlesim_node
QXcbConnection: Could not connect to display
zsh: abort (core dumped)  rosrun turtlesim turtlesim_node

Are there any solutions to this? Thanks.

The environment is Windows 10 / WSL. [..] QXcbConnection: Could not connect to display. Are there any solutions to this?

Do you have an X server running and have you setup everything to use that X server?

Please note that ROS on Ubuntu on WSL on Windows 10 is not a supported configuration, so you're bound to run into issues.

Have you restarted the X server? The X servers for Windows I know are not services, nor part of "the system", but regular programs. So you'll have to start them manually.

Yes, I restarted the X server. But failed.

Is the DISPLAY variable also set?

Well, as I wrote in my answer, this is not a supported configuration. Although it can work -- as I've seen many people set things up this way, and I've done it myself -- there is no guarantee.

Hi there, If you are interested in trying out ROS on Windows, Microsoft ported ROS to Windows and is in the process upstreaming that work to main. In the mean time, you can get started visit . We'll be integrating the documentation once the up-streaming that port has been completed.
