emacs 256 colour support

I am using ubuntu 9.04 and GNU Emacs 22.2.1

I am using the terminal to load emacs i.e. emacs -nw

However, I am 开发者_高级运维only running in 8 colours.

M-X list-colors-display

Only displays 8 colours.

In the terminal I run this command

tput colors and I get 8 displayed

How can I get full 256 colour support?

Many thanks for any advice,

Just testing on my Debian machine, I get the same as you (8 colours).

You don't say whether you are using an xterm, but in my xterm I have typed

export TERM=xterm-256color

and then emacs -nw followed by list-colors-display shows 256 colours.
