TIP

此处使用arm内核，所以相比多了个“-ports”
路径为“/etc/apt/sources.list“
遇到加锁时“sudo rm /var/lib/apt/lists/lock”

RealVNC

TIP

realvnc下载地址 https://www.realvnc.com/en/connect/download/viewer/open in new window

# 1.Enable the VNC server to start each time you log in
#   If you have a Jetson Nano 2GB Developer Kit (running LXDE)
mkdir -p ~/.config/autostart
cp /usr/share/applications/vino-server.desktop ~/.config/autostart/.
# For all other Jetson developer kits (running GNOME)
cd /usr/lib/systemd/user/graphical-session.target.wants
sudo ln -s ../vino-server.service ./.

# 2.Configure the VNC server
gsettings set org.gnome.Vino prompt-enabled false
gsettings set org.gnome.Vino require-encryption false

# 3.Set a password to access the VNC server
gsettings set org.gnome.Vino authentication-methods "['vnc']"
gsettings set org.gnome.Vino vnc-password $(echo -n 'jetbot'|base64)

# 4.Reboot the system so that the settings take effect
sudo reboot

Docker代理

# docker配置代理
sudo mkdir -p /etc/systemd/system/docker.service.d
sudo touch /etc/systemd/system/docker.service.d/proxy.conf
vi /etc/systemd/system/docker.service.d/proxy.conf
# 录入
[Service]
Environment="HTTP_PROXY=[ip]:[port]"
Environment="HTTPS_PROXY=[ip]:[port]"
# 重启（可以使用“sudo docker info”检查配置）
sudo systemctl daemon-reload
sudo systemctl restart docker

串口驱动

apt-get install python3-serial

控制台代理

# 终端输入
export ALL_PROXY=socks5://科学上网电脑IP : 端口

网络切换

# 连接
sudo nmcli device wifi connect 'SSID' password 'PASSWORD'
# 断开
sudo nmcli connection down SSID
# 删除
sudo nmcli connection del SSID
# 查看状态
sudo nmcli connection show
sudo nmcli device status
# 开启热点
sudo nmcli dev wifi hotspot ssid 'SSID' password 'PASSWORD'
# 设置开机自动连接，下方为自动连接热点
sudo nmcli connection modify Hotspot autoconnect yes

Jupyter iframe

# 编辑配置文件，vim /home/jetdot/.jupyter/jupyter_notebook_config.py，追加如下代码配置：
c.NotebookApp.token = ''
c.NotebookApp.ip = '0.0.0.0'
c.NotebookApp.tornado_settings = { 'headers': { 'Content-Security-Policy': "frame-ancestors * 'self'" }}
c.NotebookApp.disable_check_xsrf = True
c.NotebookApp.open_browser = False
c.NotebookApp.allow_root = True
# 然后删除.json密码文件
