安装tightvncserver
sudo apt install tightvncserver
启动
vncserver :1
设置远程访问密码
修改密码
vncpasswd

用vnc登录 ip:1

关闭VNC服务
vncserver -kill :1

先备份xstartup原始文件，再编辑
sudo mv -v .vnc/xstartup .vnc/xstartup.backup
sudo nano ~/.vnc/xstartup

#!/bin/sh
export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
 
exec /etc/X11/xinit/xinitrc
 
xfce4-panel &
xfsettingsd &
xfwm4 &
xfdesktop &
pcmanfm &
xfce4-terminal &
 
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
 
startxfce4 &

更改配置文件的权限：
sudo chmod +x ~/.vnc/xstartup
