Help with 2.1" display

Nobody has claimed this yet.

Describe the bug
Hey everyone!

I need some help with my Linux setup.
I tried to mess around with different settings and themes, but the result was the same:
Running python3 configure.py apparently detects the screen correctly, sets the background correctly, but all the other info like time are not being updated.

The original software provided by the manufactrer works well on Windows.

I tried to debug, but this project is too advanced for my python skills 🥲

To Reproduce
Steps to reproduce the behavior:

Run python3 configure.py
Click on 'Save and run'
Only the background is updated;

Expected behavior
Screen displaying the background and stats like the theme preview.

Environment:

Smart screen model: Turing 2.1"
Revision of this project: 3.9.6 (downloaded from releases page)
OS with version: Linux Mint 22.2
Python version: 3.12
Hardware: Intel i9-14900KF, RTX-4060 ti

Additional context

Start by reproducing the issue with python3 configure.py using the reported Turing 2.1-inch display, theme 30, and Linux environment. Read configure.py and follow the display initialization after the log entries for Drawing Image: BACKGROUND and Starting system monitoring; compare the background path with the code that sends time and system statistics. Done means the background and live stats render as shown in the theme preview.
