Hi and thanks for all the replies
This isn’t true, the Gnome SIG will continue to maintain all the xorg packages, but X11 isn’t installed as a default fallback alternative.
but i found the solution - Thanks to @siosm:
you have to install layer gnome-session-xsession and gnome-classic-session-xsession along with the xorg-x11-drv-* package sutiable for your system.
i need this because some apps (such as autohotkey & barrier / input-leap) won’t work at all and last but not least gaming with Wayland is terrible (adds +~30ms lag) , especially on Soda/Proton based-Games.
Glad to see, that it will work at least a few more years
