Package: xauth
Version: 1:1.0.2-2
Severity: normal

Hi,

After upgrading from Ubuntu 7.10 to 8.04, sometimes (see below for
an explanation of the circumstances under which this happens) I cannot
start new X applications. For instance:
$ xlogo
No protocol specified
Error: Can't open display: :0.0
$

At the same time, /var/log/Xorg.0.log shows lines like the following:
AUDIT: Mon Jun 9 12:51:39 2008: 6255 X: client 34 rejected from local host (ui$

This only seems to happen after I log in to a remote host (using "ssh
-X somehost"). After that, only starting programs locally is a
problem; starting X programs from the remote host works fine. This does
not always trigger the problem, but roughly half the time. It does not
seem to make a difference whether I log in to an Ubuntu 7.10 or 8.04
machine. On the remote host, I have the same account, with a shared
(via nfs) home directory. Ths nfs server runs Ubuntu 7.10.

Logging out from the remote machine does not help. What does help,
however, is typing "xauth list" or just "cat ~/.Xauthority" in a local
terminal window. After that, I can again start new applications.

Also, just 'cat ~/.Xauthority' appear to help. Before that, sometimes I
even get:
$ ls -l .Xauthority
ls: cannot access .Xauthority: Stale NFS file handle
$

I'm not sure whether xauth is the right package to report this to, so
please let me know if you think there's a better place to report this.
If there's anything I can do to help further diagnose this problem, do
ask.

Regards,
Vincent Arkesteijn.
