linux设置终端颜色256,如何设置我的Linux X终端以便Emacs可以访问256种颜色？

根据

this,除了将TERM设置为xterm-256color之外,还需要ncurses-term库.

好的,this还有其他一些尝试：

The xterm in Ubuntu Edgy does not advertise 256 color support by

default. To fix this you need to install a 256 color terminfo entry,and tell xterm to use it:

apt-get install ncurses-term

echo XTerm.termName: xterm-256color

>>~/.Xdefaults

xrdb -merge ~/.Xdefaults

并且：

So you need a file term/screen-256color.el in your load-path. Emacs

22 expects it to contain a terminal-init-screen defun. Emacs 21

expects it to contain a bunch of top-level forms. Here's what I use:

;;; This is for GNU Emacs 22

(defun terminal-init-screen ()

"Terminal initialization function for screen."

;; Use the xterm color initialization code.

(load "term/xterm")

(xterm-register-default-colors)

(tty-set-up-initial-frame-faces))

;;; This is for GNU Emacs 21

(if (= 21 emacs-major-version)

(load "term/xterm-256color"))

For Emacs 21,you also need to install the xterm-256color.el file from
