a. 缺失图形化工具
b.  ~/.vnc/xstartup 权限不对

1. Ubuntu 16.04 安装 VNC 及 Mate 桌面环境

Ubuntu 16.04 安装 VNC 及 Mate 桌面环境

Fluxbox  轻量级桌面       apt -y install fluxbox
XFCE     轻量级桌面       apt -y install xfce4 xfce4-goodies
mate     GNOME2桌面的分支 apt -y install ubuntu-mate-core ubuntu-mate-desktop
Cinnamon GNOME2桌面的分支 apt -y install cinnamon cinnamon-desktop-environment

add-apt-repository ppa:embrosyn/cinnamon
apt update && apt -y install cinnamon

GNOME    最常用的图形桌面 apt -y install gnome ubuntu-gnome-desktop
apt-get -y install gnome-shell gnome-panel gnome-menus gnome-session gnome-settings-daemon gnome-terminal gdm metacity nautilus

KDE      有BUG的          https://jingyan.baidu.com/article/fa4125acb7938628ac7092af.html
#apt -y install kubuntu-desktop kde-l10n-zhcn
#apt -y install  plasma-desktop dolphin  kde-l10n-zhcn  konsole kde-runtime-data kde-wallpapers
#apt-get -o Dpkg::Options::="--force-overwrite" -f install

2. 编辑 ~/.vnc/xstartup ，并赋予 +x 权限，重要
vim ~/.vnc/xstartup

1. #!/bin/sh
3. # Uncomment the following two lines for normal desktop:
4. # unset SESSION_MANAGER
5. # exec /etc/X11/xinit/xinitrc
7. #export XKL_XMODMAP_DISABLE=1
8. unset SESSION_MANAGER
9. unset DBUS_SESSION_BUS_ADDRESS
10. [ -x /etc/vnc/xstartup ] &&exec /etc/vnc/xstartup
11. [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
12. xsetroot -solid grey
13. vncconfig -iconic &
15. # x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
17. #xfce4-session &
18. mate-session &
19. #startkde &
21. #gnome-panel &
22. #gnmoe-settings-daemon &
23. #metacity &
24. #nautilus &
25. #gnome-terminal &
26. #gnome-session &

3. 安装 VNC , XRDP
apt -y install vnc4server tightvncserver xrdp xterm ntp

1. 关闭重新启动vncserver
2. vnc4server -kill :1
3. vnc4server
5. Ubuntu 14.04及以后的gnome桌面对xrdp连接支持不是很好，需要换为xfce桌面。
7. echo xfce4-session >~/.xsession
9. vim /etc/xrdp/startwm.sh
10. #在./etc/X11/Xsession前插入 xfce4-session
12. echo xfce4-session >~/.xsession
13. vim /etc/xrdp/startwm.sh
14. #在./etc/X11/Xsession前插入 xfce4-session
16. #重启xrdp
17. /etc/init.d/xrdp restart
18. service xrdp restart
