Hi:
On 3 machines that have multiple user accounts, my other users can't start Apple X11; only the user that installed it can start it up.
I figured out that before logging out if you manually delete the following file and directory, you can then log in as another user and then that person is able to run X11.
The X11 session creates a file and a directory with another file in /tmp, i.e.,
.X0-lock
.X11-unix/
If you delete these files manually before logging out, then X11 can be started with another user's account, and it all then works fine.
I am afraid I don't know how to tell Apple OS X to do delete these automatically upon logging out (/etc/csh.logout was wrong).
Thanks in advance for any advice on how to do this automatically, or other ways to cure this problem.
