If using ssh to execute a command remotely on these systems, the connection hangs if enabling X.
From macOS 11.5 (the problem exists from Scientific Linux 6 and from CentOS 8.4.2105 itself as well.):

debug3: channel 0: status: The following connections are open:

#2 x11 (t4 r4 i0/0 o0/0 e[closed]/0 fd 10/10/-1 sock 10 cc -1)
A few google searches have led me to believe it has to do with the spawning of DBUS, and the inability to close this session again.
