tlug: X Display

[Subba Rao <subb3@example.com>]

I use XDM on my system. When I login and try to "su - localuser" in
a xterm, I get the following message:

/dev/ttypc: Operation not permitted

I do get the shell prompt after this message for the "localuser".

After I set and export the DISPLAY value to :0.0 and I try to call an
X application, I get,

Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server
Error: Can't open display: :0.0

By changing the current configuration, I will be loosening the security of
X windows, but I do need other users to be able to use the same display
at the same time. How do I accomplish that? What files do I need to change?

Thank you in advance.
