-Subject: [PATCH] Fix X not having access control on startup
-
-If the auth file is empty, X allows any local application (= any user on the
-system) to connect. This is currently the case until X wrote the display
-number to sddm and sddm used that to write the entry into the file.
-To work around this chicken-and-egg problem, make use of the fact that X
-doesn't actually look at the display number in the passed auth file and just
-use :0 unconditionally. Also make sure that writing the entry was actually
-successful.
