I have used xLaunch, Multiple Windows, Start no client, Clipboard, No Access Control, no additional parameters or font server -- that is, defaults all the way.

On Putty,

When I connect to the remote Linux system, I get a delay, followed by this message:
/usr/bin/xauth: timeout in locking authority file /home/{userName}/.Xauthority

When I try to start an xterm (xterm &), I see

PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match
PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match
PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match
PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match
xterm Xt error: Can't open display: localhost:10.0

(end of lines inserted so you can read)

localhost:10.0 looked funny to me, so I forced DISPLAY to be localhost:10.0. The complaint is now

No protocol specified
xterm Xt error: Can't open display: localhost:0.0

Changing it to the actual IP of my local machine gets me the same message, but with more copies of "No protocol specified."

Thanks for all help --

  • Some ideas: 1) Run sshd in debug mode. Might get more information. 2) Check the permissions on your .Xauthority file. Or delete it and let sshd create a new one. 3) Disable SElinux. – Michael Closson Nov 06 '13 at 18:34

If you are able to use xterm as your own login, but unable to once su'ing to root, then there's an program called sux, which sorts the magic cookie out when moving from one user to another.

It's a bit of a security risk, and not to be used in a production environment, but works nicely for a home setup.

Otherwise look at a user that works,

pompt> xauth list

(Note down the following output)

10-111-11-11/unix:10 MIT-MAGIC-COOKIE-1 ce4867d5a6c0e6d5f33285aa0e163987

Then do this:

prompt> su – useryouwanttowork

(Add entire output using xauth add command)

prompt> xauth add 10-111-11-11/unix:10 MIT-MAGIC-COOKIE-1 ce4867d5a6c0e6d5f33285aa0e163987
