Causes of Error & Description
Problem Diagnosis When launching or playing Minecraft Minecraft 1.20.4 - 1.20.6 on Linux Ubuntu / Debian, the game abruptly crashes with **opengl-1282**.
Root Causes 1. **Memory Allocation**: JVM garbage collector exhaustion or insufficient RAM. 2. **Java Runtime Mismatch**: Minecraft Minecraft 1.20.4 - 1.20.6 strictly requires Java 21. Running an incompatible Java version triggers immediate crashes. 3. **Graphics Drivers & Overlays**: Incompatible third-party overlays (Discord, RivaTuner) or outdated GPU drivers causing OpenGL crashes.
Step-by-Step Resolution 1. **Verify Java Runtime**: Confirm you are executing with OpenJDK 21. 2. **Adjust Memory (RAM)**: In SuperLauncher settings, allocate between 3072MB and 6144MB of RAM. 3. **Clean Cache & Mod Conflicts**: Remove incompatible mods or reinstall clean loader libraries.
