Phil, Try reading http://wiki.tcl.tk/1829 for the tk problem. It suggests an issue with your X security which you probably want to investigate anyway.
For me things "just work" with Ubuntu. Though I should perhaps be more precise that it is Kubuntu (with KDE as the window manager) that I use rather than vanilla Ubuntu. I'd be very surprised if X was not set up securely by default though.
