System: Ubuntu
Screen: RGB 720x720
Hardware: Luckfox Pico Ultra W
Problem: After flashing the official Ubuntu system, the screen failed to power on after a week of use; rebooting and powering off did not resolve the issue. After flashing the official BuildRoot firmware, the screen initially displayed white and gray bars, which returned to normal after a while. Compiling the latest GitHub image myself rendered the screen unusable.
Request: How to ensure long-term usability of the Ubuntu system?

Firstly, due to licensing issues, we have ceased maintenance and support for the Ubuntu system, making it impossible for us to further investigate many of the problems.
The issue where the system fails to boot after running for a period of time can typically be resolved by re-flashing the system. This is generally unrelated to kernel configuration, as most kernel configuration errors would trigger a failure on the very first boot. I suspect that a particular service or application may be enabled, causing the Ubuntu system's storage usage to continuously increase over time — for example, due to constantly generated log files. After running for an extended period, the storage space may become full, leading to the boot failure. I recommend using the journalctl tool to investigate this issue.
