debian4在字符界面下如何升级到图形界面

1. 我以把该3 张DVD 的iso , mount 成功了
mount -o loop ./debian1.iso /home/george/cd1
mount -o loop ./debian2.iso /home/george/cd2
mount -o loop ./debian3.iso /home/george/cd3

2.sources.list 也改了， cat /etc/apt/sources.list

deb file:///home/george/cd1 etch contrib main
deb file:///home/george/cd2 etch contrib main
deb file:///home/george/cd3 etch contrib main

apt-get update && apt-get upgrade

apt-get install xorg
dpkg-recognize xserver-xorg
apt-get install kde-core kdm kde-i18n-zhcn
apt-get install ttf-bitstream-vera ttf-arphic-uming ttf-freefont
adpkg-recognize locales 设置中文

reboot
