Worked on enhancing the stability of PrismLauncher’s Linux display handling by addressing a critical reliability issue. Focused on C++ development for game and Linux environments, the work introduced logic to detect the absence of the xrandr executable and automatically fall back to the xf86videomode implementation. This approach prevented runtime errors and ensured consistent graphics behavior, particularly in headless or minimal Linux setups. The solution involved defensive programming practices, such as checking for external dependencies and maintaining clear, maintainable code paths. By improving LWJGL-based rendering reliability, the changes reduced user impact and support needs across diverse Linux configurations.
