Does vncviewer require an X server to work?
I have installed Ubuntu Server 12.04, as well as the xtightvncviewer package. When running vncviewer, it claims that it cannot find the display.

Yes you need X server. Won't work from Linux server with no X server.
Assuming you have an X server, you can run
export DISPLAY=:0
unless your display manager is not running on the default X display.
