1 在Ubuntu上安装VNC Viewer客户端

1、首先在自己的电脑Ubuntu系统上安装VNC Viewer客户端

2、下载Linux版本的VNC Viewer客户端软件

• VNC Viewer客户端下载地址

3、下载好之后，直接双击VNC-Viewer-5.3.1-Linux-x86.deb就可以安装

4、打开VNC Viewer界面如下：

2 在Jetson nano中安装 VNC 服务端

可以先通过ssh username@ip连接到Jetson nano上，然后安装vino

1、更新源

sudo apt update

2、安装VNC server服务端

sudo apt install vino

zhihui@zhihui-desktop:~$ sudo apt install vino

默认，Jetson nano好像已经安装了VNC server服务端了！

3、最好重新启动一下Jetson nano

sudo reboot

4、然后在Jetson nano的桌面显示的情况下的terminal（不是用ssh连接的terminal）中启动VNC server

/usr/lib/vino/vino-server

正确启动如下：

zhihui@zhihui-desktop:~$ /usr/lib/vino/vino-server

3 开始通过VNC Viewer连接Jetson nano桌面

首先，要确保Jetson nano和你自己的电脑连接的是同一个局域网，你连接到同一个wifi就可以！

1、获取Jetson nano的IP地址

ifconfig

我获取的Jetson nano的ip地址为：192.168.2.40

2、把这个ip地址填入到VNC Viewer中的：VNC Server

3、点击连接Connect，然后提示未加密连接，直接点击继续就可以！

4、成功连接到Jetson nano的桌面

但是，这种方式连接到桌面之后延迟太高，基本上敲一个命令，要4秒左右才能刷新出来！！！所以，如果有外置显示器，最好还是整一个外置的显示器吧！
