--- Comment #19 from Martin Bříza mbriza@redhat.com --- Back to the xauth problem - The directory is being created on runtime, so I'll just change the path to /var/run/sddm to not complicate things for now. Message about the nonexistent file is benign. I'm just pushing the sources and will build the package.
Neal could you please report a bug against sddm with the backtrace? We'll discuss the matter further on in there. Thank you.
