Jetson搭建配置VNC Server（Xavier/Nano/NX...）

在Jetson上搭建一个VNC服务器，从而允许其他设备通过网络访问Jetson的Linux图形界面进行远程工作，并避免了连接HDMI显示器、USB键盘或鼠标的需要。
如下时搭建VNC服务器的过程，搭建完成后即可通过ViewVNC进行远程访问:

步骤一、安装vino

$sudo apt update 
$sudo apt install vino

步骤二、Enable VNC 服务（此时手动可打开vnc server）

每次登陆时使能VNC Server：
sudo ln -s ../vino-server.service   /usr/lib/systemd/user/graphical-session.target.wants

配置VNC server:
$gsettings set org.gnome.Vino prompt-enabled false
$gsettings set org.gnome.Vino require-encryption false

额外添加并手工启动VNC Service：
-1) Edit the org.gnome.Vino schema to restore the missing "enabled" parameter
$sudo vi /usr/share/glib-2.0/schemas/org.gnome.Vino.gschema.xml  
Add this key: （最后）
    <key name='enabled' type='b'>
      <summary>Enable remote access to the desktop</summary>
      <description>
        If true, allows remote access to the desktop via the RFB
        protocol. Users on remote machines may then connect to the
        desktop using a VNC viewer.
      </description>
      <default>false</default>
    </key>

-2) Compile the schemas for Gnome:
$sudo glib-compile-schemas /usr/share/glib-2.0/schemas

-3) Now the screen sharing panel in unity-control-center works... but this is not enough to get vino running! So you need to add in the programs at session start: Vino-server with the following command line:
$/usr/lib/vino/vino-server

步骤三、设置VNC登陆密码('12345678' 修改为自己的密码)

$gsettings set org.gnome.Vino authentication-methods "['vnc']"
$gsettings set org.gnome.Vino vnc-password $(echo -n '12345678'|base64)

步骤四、重启机器，验证是否设置vnc 成功

$sudo reboot

步骤五、设置开机自启动VNC Server

The VNC server is only available after you have logged in to Jetson locally. If you wish VNC to be available automatically, use the system settings application to enable automatic login.

$gsettings set org.gnome.Vino enabled true 

$mkdir -p ~/.config/autostart
$vi  ~/.config/autostart/vino-server.desktop

[Desktop Entry]
Type=Application
Name=Vino VNC server
Exec=/usr/lib/vino/vino-server
NoDisplay=true

连接VNC Server

Use any standard VNC client application to connect to the VNC server that is running on Linux for Tegra. Popular examples for Linux are gvncviewer and remmina. Use your own favorite client for Windows or MacOS.

To connect, you will need to know the IP address of the Linux for Tegra system. Execute the following command to determine the IP address:

$ifconfig

Search the output for the text "inet addr:" followed by a sequence of four
numbers, for the relevant network interface (e.g. eth0 for wired Ethernet,
wlan0 for WiFi, or l4tbr0 for the USB device mode Ethernet connection).

设置显示桌面分辨率Setting the Desktop Resolution

如果没有显示器连接，默认VNC 连接后的分辨率为640x480 ，通过修改添加如下内容，将其默认VNC分辨率设置

$sudo vi /etc/X11/xorg.conf 

Section "Screen"
   Identifier    "Default Screen"
   Monitor       "Configured Monitor"
   Device        "Tegra0"
   SubSection "Display"
       Depth    24
       Virtual 1920 1080 # Modify the resolution by editing these values
   EndSubSection
EndSection
