  1. Use the dpkg-reconfigure command to regenerate locale files non-interactively:
dpkg-reconfigure -f noninteractive locales

2. Auto-start Configuration​

This section uses a GPIO program as an example for auto-start, with the absolute path being /home/linaro/gpio.py. Please modify corresponding locations according to your actual files and paths.

2.1 Desktop Auto-start​

  1. First, create a new startup.sh using the following command: (K1 Pro default in /home/linaro)
touch startup.sh
  1. Open the startup.sh script file and enter the following content:
#!/bin/sh
sudo python3 gpio.py
  1. Grant permissions to the startup.sh script file:
sudo chmod 777 startup.sh
  1. Create auto-start file:
cd .config && mkdir autostart
cd autostart && sudo nano start.desktop
  1. Enter the following content:
[Desktop Entry]
Type=Application
Exec=/home/linaro/startup.sh
  1. Restart:
sudo reboot

2.2 Adding Auto-start in rc.local Script​

  1. Open /etc/rc.local script and add a line before exit 0:
sudo python3 /home/linaro/gpio.py &
  1. Restart:
sudo reboot

2.3 System Manager Auto-start Settings​

  1. Create a new configuration file for the auto-start service at /etc/systemd/system/gpio.service, enter the following content:

Description=start oled

[Service]
Type=simple
Restart=always
RestartSec=5
ExecStart=/home/linaro/gpio.py

[Install]
WantedBy=multi-user.target
