launcher) NOTE: If a value contains spaces, you should define it with double quotes: launcher_name="Custom
launcher" NOTE: Values are always treated as strings NOTE: Will merge "env_variables" from config file and
overwrite same variables
-j JVM_ARGS, --jvm-args JVM_ARGS
extra arguments for Java separated with spaces (Ex.: -j="-Xmx6G -XX:G1NewSizePercent=20") NOTE: You should

β οΈ NOTE: CLI arguments will overwrite config
You can use micro-minecraft-launcher in your modpack. For that, create configuration file (see section below) and install custom profile (
versions/version_id/version_id.json
) and it's extra libraries if needed (ex. forge)
- To download executable file, go to the link https://github.com/F33RNI/micro-minecraft-launcher/releases/latest and download the file for your device
- Alternatively, you can build the app yourself. For this, refer to the
ποΈ Build from Source
section
With configuration file, users can just lauch executable file without any other arguments For that, create file named
.micro-minecraft-launcher.json
in the same directory as launcher and specify whatever you want in it

On linux, just run launcher with DRI_PRIME=1
(for open-source drivers) or prime-run
(for proprietary driver)
- ex.:
DRI_PRIME=1 ./micro-minecraft-launcher-1.2.dev7-linux-x86_64
- ex.:
prime-run ./micro-minecraft-launcher-1.2.dev7-linux-x86_64
You need to manually specify what GPU launcher and java.exe should use
This tutorial is copied from https://pureinfotech.com/set-gpu-app-windows-10/ I don't have windows, so idk will it work or not
- Open Settings on Windows 10.
- Click on System.
- Click on Display.
- Under the "Multiple displays" section, click the Graphics settings option.
- Select the app type using the drop-down menu: Classic app β traditional (Win32) desktop programs.
- Click the "Browse" button and locate the locally downloaded "java.exe" by launcher
- Use the drop-down menu and select the app.
- Click the Add button.
- Set GPU for app
- Click the Options button.
- App GPU options
- Set the graphics card preference to use for the app: High performance β runs the app on the most capable GPU, usually an external or discrete graphics processor. Click the Save button.
The problem is related to the libglfw.so library on Linux, so you need to manually recompile it from source
# Select working dir (optionally)
cd "$HOME/Downloads"
# Clone repo
git clone https://github.com/glfw/glfw.git && cd glfw
# Build it
cmake -S . -B build -D BUILD_SHARED_LIBS=ON -D GLFW_BUILD_EXAMPLES=OFF -D GLFW_BUILD_TESTS=OFF -D GLFW_BUILD_DOCS=OFF -D GLFW_BUILD_WAYLAND=ON -D GLFW_BUILD_X11=ON && cmake --build build
# Copy shared libs
mkdir -p "$HOME/.local/lib/glfw" && cp build/src/libglfw* "$HOME/.local/lib/glfw/"
# Delete repo (optional)
cd ..
rm -rf glfw
# Select working dir (optionally)
cd "$HOME/Downloads"
# Clone glfw-wayland from BoyOrigin
git clone --recursive https://github.com/BoyOrigin/glfw-wayland.git && cd glfw-wayland
# Or my fork (it's the same, just in case)
# git clone --recursive https://github.com/F33RNI/glfw-wayland.git && cd glfw-wayland
# Make sure you setup git in your system properly
# If not, run this
# git config --global user.name "You name"
# git config --global user.email "You email"
# In case of warning / error try to run this 2 times
./applyPatches.sh
# Build patched version without X11
cd glfw-wayland
cmake -S . -B build -D BUILD_SHARED_LIBS=ON -D GLFW_BUILD_EXAMPLES=OFF -D GLFW_BUILD_TESTS=OFF -D GLFW_BUILD_DOCS=OFF -D GLFW_BUILD_WAYLAND=ON -D GLFW_BUILD_X11=OFF && cmake --build build
# Copy shared libs
mkdir -p "$HOME/.local/lib/glfw" && cp build/src/libglfw* "$HOME/.local/lib/glfw/"
# Delete repo (optional)
cd ../..
rm -rf glfw-wayland
Specify path to shared lib in jvm_args
(in config) or using --jvm-args
argument like so:
{
"game_dir": ".",
"id": "fabric-loader-0.15.11-1.20.1",
"jvm_args": [
...
"-Dorg.lwjgl.glfw.libname=/path/to/.local/lib/glfw/libglfw.so"
],
...
}
