CentOS 远程桌面 Ubuntu

1、系统软件设置
CentOS端：
查看是否安装了vnc软件
# rpm -q vnc vnc-server

package vnc is not installed
vnc-server-4.1.2-14.e15_3.1
上面信息就是说，vnc没有安装，而vnc-server已经安装了。
那么，安装 vc
# yum install vnc
如果vnc-server没有安装，那么
# yum install vnc-server

Ubuntu端：
安装vnc4server
$ sudo apt-get install vnc4server

设置密码
$ vncpasswd
password:
verify:
$ vim ~/.vnc/xstartup

#!/bin/sh
# Uncomment the following two lines for normal desktop: 


#unset SESSION_MANAGER 


#exec /etc/X11/xinit/xinitrc 


[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup 


[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources 


xsetroot -solid grey 


vncconfig -iconic & 


x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & 


x-window-manager &

修改之后是：
注释最后两行，也就是在前面加 #
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &

然后加上
gnome-session &

$ vnc4server
