Yes. It arises from your ssh connection. You are probably using the -Y or -X option with xauth. > And if so, is there a simple solution? Perhaps. The error you have is caused by one of two things: 1. incorrect SELinux settings on the ~/.Xauthority file or your home directory. Run restorcon -vR ~ to fix those. 2. incorrect ownership or permissions on ~/.Xauthority. The second condition can also be triggered by logging in via ssh as one user and su -l to another on the remote host. In my case I find that the second circumstance is the most frequent cause of the exact error you report. HTH -- *** E-Mail is NOT a SECURE channel *** James B.
