Broken Remote X Over SSH in Gentoo Linux?
This might be the reason for some of the problems I've been having lately getting a previously working remote X to work from work to my
Gentoo Linux system with the $DISPLAY variable just not working. Anyway, the mailing list came to the rescue again with
these two links telling you to comment out the DISPLAY variable declaration in
/etc/security/pam_env.conf to fix it.
