As of v10, Red Hat Enterprise Linux won’t support X11. Other major OSes are phasing it out in favour of Wayland.
In late November, Red Hat engineer Carlos Soriano Sanchez posted on the company’s blog to confirm that as of RHEL 10, X.Org server and other X servers (except Xwayland) will be removed.
Sanchez also uploaded a number of posts to his Mastodon channel detailing the work involved in maintaining the X11 infrastructure, which requires a full-time dedicated engineer. He justified Red Hat’s decision because of the extra burden on the quality engineering team, which currently has to test both Wayland and X.Org Server.
