+Subject: [PATCH] Explicitly stop Xorg when starting fails
+
+When Xorg starts but there is an error, stop it explicitly instead of assuming
+that X exits itself. This avoids a possibly lingering Xorg process in the
+XorgDisplayServer instance. Add a check and warning message if Xorg is
+restarted too early (shouldn't happen).
