Can't connect to X

[joaomamede]

I was running an old script (late 2019) and now I have this error when importing pynput.

Any advice?

In [1]: import pynput

ImportError: this platform is not supported: ('failed to acquire X connection: Can\'t connect to display ":0": b\'No protocol specified\\n\'', DisplayConnectionError(':0', b'No protocol specified\n'))

Try one of the following resolutions:

 * Please make sure that you have an X server running, and that the DISPLAY environment variable is set correctly

I suggest a search on the term can't connect to display no protocol specified.

I would first test running the script from a terminal application launched from the DE---that way, you will have all X related environ variables set correctly. Have you updated you system since 2019 and started using Wayland? If so, you will only be able to interact with applications launched under Xwayland.

I will close this issue, as it is not directly related to this library, but feel free to continue commenting.
