[Nix-dev] The X unix socket

[Steve Roggenkamp]

This is the same as my Debian installation.

This is actually a UNIX socket the X Windows server uses for 
interprocess communication.  The socket is owned by the X windows server 
which runs as root since it has to control the display device.  The 
permissions allow an arbitrary client to connect with the X Windows server.

I think this is how all Linux have X Windows configured, or at least my 
Debian and Ubuntu installations.

I'm thinking you would have to change the Xorg code to change the 
permissions since this socket gets opened when the Xorg server starts.  
Then I suppose you could create a group that would be allowed to 
communicate with the socket.  I've not done that much coding with UNIX 
sockets, so I'd have to do some research to know whether this would even 
be feasible.

Hope this makes sense.
