/etc/security/pam_env.conf overrides the $DISPLAY variable so that $DISPLAY is set to hostname.domainname:0.0 when one ssh's into an affected machine. Reproducible: Always Steps to Reproduce: 1. emerge =pam-0.7.-r3 openssh 2. Enable X-forwarding. 3. Connect to the afflicted computer. 4. Fire up an X program. Actual Results: I recieved errors when I attempted to run an X program through an SSH tunnel. The errors all amounted to "Cannot open display: domainname.hostname:0.0" Expected Results: Opened the X application on the remote machine. I have attached a patch that resolves this issue.
