1.3.2 Getting Started Configuration

Default Login Accounts​

Before configuring the system, you need to log in first. The RDK S600 system provides two default accounts:

  • Standard user: username sunrise, password sunrise
  • Superuser (root): username root, password root

Connecting to Wi-Fi​

Refer to the Ubuntu 24.04 Wi-Fi connection tutorial.

Enabling SSH Service​

The current system version has the SSH login service enabled by default. You can use the following methods to turn the SSH service on or off.

For using SSH, please refer to Remote Login - SSH Login.

Setting Login Mode​

Automatic Login on Character Terminal​

Modify the serial-getty@ttyS0.service file to set up password-less login as follows:

  1. Open serial-getty@ttyS0.service
# Log in as root user
vim /usr/lib/systemd/system/serial-getty@ttyS0.service
# Log in as sunrise user
sudo vim /usr/lib/systemd/system/serial-getty@ttyS0.service
  1. Change the line containing ExecStart=-/sbin/agetty to:
ExecStart=-/sbin/agetty -a root --keep-baud 921600,115200,38400,9600 %I $TERM

Parameter explanation: The -a parameter specifies the username for automatic login. -o '-p -- \\u' adds additional customization to the login process: preserves the current environment variables and displays the username in the login prompt.

  1. After restarting, the user will be logged in automatically.

Automatic Login on Graphical Terminal​

To be updated.

Setting Up Chinese Environment​

  1. Install the command packages:
sudo apt install language-pack-zh-hans language-pack-zh-hans-base fonts-wqy-microhei
  • language-pack-zh-hans: Contains Chinese language translation files, allowing the system interface to display in Chinese.
  • language-pack-zh-hans-base: Base language pack providing basic Chinese support.
  • fonts-wqy-microhei: Installs Chinese fonts.
  1. Open the terminal and enter the following command to open the language configuration file:
sudo vim /etc/default/locale

Add or modify the following content in the file:

LANG=zh_CN.UTF-8
LANGUAGE=zh_CN:zh
LC_ALL=zh_CN.UTF-8
  1. Execute the following command to update the configuration:
fc-cache -fv
source /etc/default/locale

Setting Up Chinese Input Method​

After setting up the Chinese environment, the system's built-in input method is supported by default. Press the Super (Windows key) + Space key combination to switch between different input methods.

Setting Up RDK Studio​

RDK Studio is an AI-native desktop workspace designed for robotics development. It integrates Moss conversation, project workspace, device connection, remote development, flashing, local models, and on-board agents into a single native window.

For the usage instructions of RDK Studio, please refer to the RDK Studio User Manual.

NoMachine Configuration​

NoMachine currently does not support apt download. You need to obtain the deb package from the official website.

Official NoMachine download URL: NoMachine Download

Download the installation package

After entering the official website, find the ARM64 version of the installation package suitable for RDK S600 and click Download.

NoMachine Configuration diagram

Installation

sudo apt update; sudo apt upgrade -y   // Ensure the current software is up to date
dpkg -i nomachine_*_arm64.deb

Configuration and Startup

  1. Configure the server to allow remote connections:

    sudo systemctl start nxserver

  2. Set NoMachine to start on boot:

    sudo systemctl enable nxserver

  3. Set EGL Capture to yes. This is a screen capture feature provided by NoMachine, mainly used to improve the remote desktop experience in specific display server environments:

    sudo /etc/NX/nxserver --eglcapture yes

    This command takes effect after a reboot. You can double-check with the following command; EGL Capture has been enabled indicates that the feature has been written to the configuration file.

    if [ -f "/usr/lib/systemd/user/org.gnome.Shell@wayland.service" ] && grep -q "nxpreload.sh" "/usr/lib/systemd/user/org.gnome.Shell@wayland.service" && [ -f "/usr/share/applications/org.gnome.Shell.desktop" ] && grep -q "nxpreload.sh" "/usr/share/applications/org.gnome.Shell.desktop" && [ -f "/usr/NX/etc/node.cfg" ] && grep -q "EnableEGLCapture 1" "/usr/NX/etc/node.cfg"; then echo "EGL Capture has been enabled"; else echo "Not enabled"; fi

  4. Restart the NoMachine service:

    sudo systemctl restart nxserver

Restart the S600

Due to NXServer configuration issues, connecting directly after performing the above operations will result in a black screen. A reboot is required before use.

For using NoMachine, please refer to Remote Login - NoMachine Login.

User Management​

Changing the username

Using the new username usertest as an example:

# Terminate all processes of the sunrise user
sudo pkill -u sunrise
# Rename the sunrise user to usertest
sudo usermod -l usertest sunrise
# Change the user's home directory to /home/usertest
sudo usermod -d /home/usertest -m usertest
# Change the user password
sudo passwd usertest

Finally, update the automatically logged-in username for the desktop service:

  • gdm: RDK S100 default desktop service. Change AutomaticLogin = sunrise in the /etc/gdm3/custom.conf file to AutomaticLogin = usertest.
  • lighttdm: Change autologin-user=sunrise in the /etc/lightdm/lightdm.conf.d/22-hobot-autologin.conf file to autologin-user=usertest.

Adding a new user

Using the new user usertest as an example:

sudo useradd -U -m -d /home/usertest -k /etc/skel/ -s /bin/bash -G disk,kmem,dialout,sudo,audio,video,render,i2c,lightdm,vpu,gdm,weston-launch,graphics,jpu,ipu,vps,misc,gpio usertest
sudo passwd usertest
sudo cp -aRf /etc/skel/. /home/usertest
sudo chown -R usertest:usertest /home/usertest

You can also refer to the username change method to set the newly added user as the automatically logged-in user.
