      Cause (the user action or circumstances that trigger the bug):

      Default setup of GNOME Remote Desktop.

      Consequence (what the user experience is when the bug occurs):

      User can't connect to the remote desktop.

      Workaround (if available):

      In /etc/gdm/custom.conf set
      {code:bash}
      [daemon]
      ...
      PreferredDisplayServer=none
      {code}

      Make also sure to set SELinux to Permissive.

      Result (mandatory if the workaround does not solve the problem completely):

      Can connect correctly.
