How does GDM authenticate to the X Server?
Given that you usually have to authenticate to the X Server by way of a "magic cookie" stored in the .xauthority file in the user's home directory: How does GDM (like most login processes, running as root, I would assume) connect to the X Server in order to draw the login display? Does it use any .xauthority files stored in the root user's home directory or does it bypass authentication altogether?
