Remove literally all of these exports. You also have a intel GPU which will drive the majority of your actual rendering. Also for nvidia wayland anything to work you'll need https://wiki.archlinux.org/title/NVIDIA … de_setting did you do that?

Re: Failed xcb connection with Hyprland(i.e wayland compositor)

Thank you "#Forum Modretor", I have tried this one.
By my only two time previous experience or just observation with this error. It happens when an X11 desktop environment already available or some application of it, that I don't know why, from where and which one ???  affecting it and in what manner. Not relatable error for which i have searched through internet and got nothing there. 

And now even cagebreaks wayland compositor shows this error. I doubt on some X11 desktop environment application behind this crime. 

While Sway didn't show this error or may be it plans to show me this at next.
Because at first error:
It forcing me to tradeoff nvidia with nouveau, which i rejected.
And also sorry for the late reply.
