xinit start error

[ToddAndMargo]

Hi All,

Fedora 39
mate-utils-common-1.26.1-3.fc39.noarch
xorg-x11-server-Xorg-1.20.14-35.fc39.x86_64

With lightdm removed from my system, when I run "mate-session" from the 
a user's command line, I get

      $ mate-session
      ** (mate-session:8363): WARNING **: 20:26:30.590: Cannot open display:

Running xinit from the user's command line give me:

     $ xinit
     (EE)
     Fatal server error:
     (EE) Server is already active for display 0
	   If this server is no longer running, remove /tmp/.X0-lock
            and start again.
     (EE)
     (EE)
     Please consult the The X.Org Foundation support
	 at http://wiki.x.org
     for help.
     (EE)
     X connection to :0 broken (explicit kill or server shutdown).

Removing /tmp/.X0-lock does ot help

How do I troubleshoot this?

Many thanks,
