Xlib.error.DisplayConnectionError: Can't connect to display ":0": b'Authorization required, but no authorization protocol specified\n' on Wayland

Description

Can not send whatsapp text message in Fedora 38 with Wayland

To Reproduce

import pywhatkit
pywhatkit.sendwhatmsg(phone_no="520000000001", message="Hi", wait_time=15, time_min=33)

Same config in Windows 10 works fine. It seems to be a problem with Wayland.

• OS: Fedora 38 Wayland
• Browser: Google Chrome Versión 112.0.5615.121 (Build oficial) (64 bits)

This error is exclusively on Wayland OS.

I can confirm that if you run it on a KDE with X11 like Fedora 38 KDE it just works as designed (be sure to log in with X11 not Wayland).

Pywhatkit needs a Wayland update, not sure if it is a small task but since all linux seems to move to Wayland it needs to get fixed.

@george72 Or Wayland needs an update ;)

Wayland is still under development, and there are still applications and behaviours that don’t work as expected, you may find that some applications have not been updated to work properly in Wayland and currently the only way these applications will run is using Xorg instead of Wayland. source

I had to change Fedora 38 from Wayland to Xorg to be able to run Pywhatkit.

Expecting a Wayland compatibility update does not look like the way to go. It's better to have Pywhatkit running natively on Wayland.

Steps to change Fedora Wayland to Xorg:
Changing the default GNOME session via configuration file

As an alternative, this change can be made by editing a configuration file /etc/gdm/custom.conf.

Open /etc/gdm/custom.conf and uncomment the line:

WaylandEnable=false

Add the following line to the [daemon] section:

DefaultSession=gnome-xorg.desktop

Save the custom.conf file.

Logout or reboot to enter the new session.
