There's the problem, then. You do not have "thinkpad" as an entry in your /etc/hosts file, so the system is unable to lookup "the IP address" for its own hostname. X sessions tend to frown upon that. Adding "thinkpad" to the 127.0.1.1 line should take care of this. You can retain the other fields, and simply use thinkpad as a second alias.
