Remove the Ubuntu-specific rules that made Xorg the default for Nvidia.
Updated Revert-data-Disable-GDM-on-hybrid-graphics-laptops-with-v.patch
to ensure Nvidia 5xx drivers always get Wayland as the default unless
there’s a stronger reason why it won’t work (like modeset has been
disabled on the kernel command line).
Also refresh the patch description with a more recent justification.
