System Configuration

1. Language Settings

Use Vim to edit the /etc/locale.gen file, comment out unnecessary locales, and enable the required ones.
```
vim /etc/locale.gen
```

To switch from Chinese to English, perform the following actions in the file.

Comment out the line: zh_CN.UTF-8 UTF-8.
Uncomment the line: en_US.UTF-8 UTF-8.

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

2. Auto-Start Configuration

This section takes the GPIO program as an example for auto-start. The absolute path of the program is /home/luckfox/gpio.py. Please adjust the file paths according to your actual setup.

2.1 Desktop Auto-Start

First, create a startup.sh script using the following command (Omni3566 by default is located in /home/luckfox):
```
sudo touch startup.sh
```
Open the startup.sh script and add the following content:
```
#!/bin/sh
sudo python3 gpio.py
```
Grant execute permissions to the startup.sh script:
```
sudo chmod 777 startup.sh
```

Create the autostart directory and file:

cd .config && mkdir autostart
cd autostart && sudo nano start.desktop

Add the following content to the start.desktop file:

[Desktop Entry]
Type=Application
Exec=/home/luckfox/startup.sh

Reboot the system:
```
sudo reboot
```

2.2 Add Auto-Start in `rc.local` Script

Open the /etc/rc.local script and add the following line before exit 0:
```
sudo python3 /home/luckfox/gpio.py &
```
Reboot the Core3576:
```
sudo reboot
```

2.3 Set Auto-Start via System Manager

Create an auto-start service configuration file in /etc/systemd/system/gpio.service and add the following content:

[Unit]
Description=start oled

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

[Install]
WantedBy=multi-user.target

Enable a service so that it starts automatically at system boot:
```
sudo systemctl enable gpio.service
```
Reboot:
```
sudo systemctl restart gpio.service
```
Reboot Omni3576:
```
sudo reboot
```
If you want to disable a service so that it does not start automatically at system boot:
```
sudo systemctl disable gpio.service
```

3. Installing Input Method

Install the desktop terminal application.

sudo apt update
sudo apt install xfce4-terminal

Install the IBUS input method framework and related components.

sudo apt update
sudo apt install ibus-gtk ibus-gtk3 ibus ibus-libpinyin ibus-wayland at-spi2-core

Start the IBUS background service.
```
ibus-daemon -drx
```
Configure the Chinese input method.
```
ibus-setup
```
- In the setup window:
  - Navigate to Input Method -> Add
  - Select Chinese -> Intelligent Pinyin
  - Click Close to exit
Reboot the development board.
```
reboot
```
- After rebooting, left-click the keyboard icon in the upper-right corner and select Chinese.
Install the im-config configuration tool and set IBUS as the default input method framework.
```
sudo apt install im-config
im-config -n ibus
```
