Port Access Permission

If you can’t find the port when launching the Ubuntu HMI:

Method 1: Add the current user to the dialout group
```
sudo usermod -a -G dialout $USER
```
After execution, apply the permissions:
- Current terminal only: newgrp dialout
- System-wide: sudo reboot
Method 2: Launch the HMI with sudo
```
sudo wuji-hand-hmi
```

Display Scaling Warning

If a display scaling warning appears during startup, the system display scaling ratio is greater than 100%. Adjust the display scaling to 100% (1:1) in your system settings, then restart the HMI.
