Does vncviewer require X locally?

Question

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.

Answer 1

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.
