Fix: Screen sharing black screen issue due to xdg-desktop-portal conf…

[p3p3p3k4z]

Descripción

This pull request addresses a common issue where screen sharing on Wayland (specifically Hyprland) results in a black screen in Chromium-based browsers, often due to conflicts between multiple xdg-desktop-portal instances.

The solution has two parts:

Modified xdg.sh: Removed the code that explicitly starts xdg-desktop-portal-gtk to prevent it from conflicting with xdg-desktop-portal-hyprland.

Modified setup-fedora.sh: Added a step to automatically create a configuration file at /etc/xdg/xdg-desktop-portal/hyprland-portal.conf that sets default=hyprland. This ensures the Hyprland portal is prioritized system-wide, providing a robust solution for users with multiple desktop environments installed.

These changes ensure a more stable screen-sharing experience for new Fedora installations using this configuration.

Context

This change is necessary to fix a long-standing bug where users with multiple desktop environments installed (like GNOME alongside Hyprland) experience a black screen when trying to share their screen. The xdg.sh script, as it was, would start conflicting portals, and the setup-fedora.sh did not provide a mechanism to set Hyprland as the default portal, leaving the issue to manual intervention. This PR solves the problem by making the fix part of the standard setup process.

Additional Notes

This fix is particularly important for Fedora users, as the default installation process often leaves multiple desktop portals, which leads to this screen-sharing issue. The solution provides a clean and reliable fix without requiring manual user intervention after installation.

@p3p3p3k4z I am currently not loading xdg.sh on Autostart anymore. The xdg-portals will be enabled in the background. No issues so far on Arch.

Do you think that this script is still needed?

[p3p3p3k4z]

If the service no longer loads, then I don't see the need for it. In my case, I made that modification to solve the error, due to Wayland issues.

Would be great if you could remove the execution of xdg.sh in the autostart.conf and try again.
