Red Hat has formally confirmed what many were thinking: Red Hat Enterprise Linux 10 will be doing away with X.Org Server support aside from XWayland.
For those making use of the Red Hat Enterprise Linux 10 in a desktop setting, RHEL10 due for release in H1’2025 will be Wayland-focused. X11 client support will only come via XWayland.
This does also further solidify the X.Org Server in effect being dead upstream. Red Hat engineers were typically the ones managing new X.Org Server releases as well as carrying on with various bits of development.
I assume you’re talking about X over SSH? That’s possible with Wayland via Waypipe. Also I’m not sure why RDP would require X, just a compositor being able to forward the video over network (which is perfectly possible with Wayland) and accepting inputs over network as well, which to my knowledge isn’t part of Wayland. Quick check says Gnome already offers RDP and that’s Red Hat’s DE.
Currently Gnome will only allow you to connect to a logged in session. It is more like screen sharing than RDP usually is.
