Installed yesterday, ubuntu.
How can I change the username? Right now it's "parallels". I added a new user on the command line, but I don't see a way to logout / login back in....

How do I spin up an X server? I have XQuarts installed on my mac. When I run xemacs, it complains that it can't connect to the X server.

Thanks!
