For this tutorial you need to have L4T Linux set up and updated.

This is a simple guide(as simple as I could make it) to installing all necessary things to get Minecraft Java Edition up and running.

I basically compiled a full version of various different tutorials I found scattered around that I used to make Minecraft work and play normally.

• Open Terminal
• Type all of the following stuff in Terminal

sudo apt update

• Install the following dependencies:

sudo apt install openjdk-8-jdk
sudo apt install gradle openjdk-8-jdk libx11-dev xorg-dev

• Soft link libjawt

sudo ln -s /usr/lib/jvm/java-8-openjdk-arm64/lib/aarch64/libjawt.so /usr/lib/libjawt.so

• Compile LWJGL

git clone https://github.com/LWJGL/lwjgl
cd lwjgl
ant generate-all
ant compile_native

• Copy Binaries

mkdir -p ~/.minecraft/natives
cp ~/lwjgl/libs/linux/liblwjgl.so ~/.minecraft/natives/
cp ~/lwjgl/libs/linux/libopenal.so ~/.minecraft/natives/

• Setup environment variable (you need to run this command in terminal every time you close terminal and re-open it to launch Minecraft again otherwise the game will crash)

export _JAVA_OPTIONS='-Djava.library.path=/home/YOURUSERNAME/.minecraft/natives/'

• Play Minecraft

wget https://s3.amazonaws.com/Minecraft.Download/launcher/Minecraft.jar
java -jar Minecraft.jar

• Use your Minecraft Account to Login to the launcher
• Choose the version you want to play in settings (has to be Minecraft 1.12.2 or lower, newer versions make the game crash)
• Click Play and if you did everything right it should launch and play without a problem
• NOTE: If you want to use Optifine with it just download the Optifine jar for your version (again 1.12.2 or lower) and run the following command and click install:

java -jar Optifine(version number).jar

• Then when you start the Minecraft launcher again a new profile should come up named Optifine, just start Minecraft with that profile instead of your other one.
• Also apparently if you type into Terminal "sudo jetson_clocks" it will give you more fps ingame? Not tested it yet.

One advice, you can add java arg in minecraft launcher..

the version of LWJGL you compile is 2.X or 3.X? Minecraft had moved their backend from LWJGL2 to LWJGL3 since 1.13.X , I only got LWJGL2 natives compiled,how is yours?

Mine is also only LWJGL2 hence why Minecraft up till version 1.12.2 runs only.

The LWJGL3 is offcially released linux-arm64 nighty version,shipping the natives too,would you try it out? I currently don't have access to my Switch.

 

[OkazakiTheOtaku]

How well does this run, FPS wise?

 

[Menchen]

How well does this run, FPS wise?

With optifine shuold be over 180fps if you "overclock"

 

[RiceAlex]

With sudo jetson_clocks it should work like this,btw fullscreen is broken in the version above 1.7.X , It will draw a 720x1280 framebuffer while the screen is 1280x720.

 

[OkazakiTheOtaku]

With optifine shuold be over 180fps if you "overclock"

Do you know what optifine + standard clock looks like? At least 60?

 

[Menchen]

Do you know what optifine + standard clock looks like? At least 60?

With a new world 80+ fps, I think.

tested about 40fps barely playable

Hm...I wouldn't agree that 40fps is "barely playable" considering a lot of games in Horizon run at ~30 but I digress. Interesting. I'm wondering how much you could squeeze out of a FTB pack with or without overclocking. Very interested in trying this with Sky Factory, for example, but I don't have a spare SD card on hand for L4T.

 

[OverkillLabs]

In my tests I usually get 60fps when there's not a lot of huge buildings or crazy stuff happening(With Optifine)

is anyone else getting this when they go to compile lwjgl?
i get this output right after running ant compile_native and any help would be wonderful.

compile:
[core] Compiling 249 source files to /home/alexs2412/lwjgl/bin
[core] warning: [options] bootstrap class path not set in conjunction with -source 5
[core] error: Source option 5 is no longer supported. Use 6 or later.
[core] error: Target option 1.5 is no longer supported. Use 1.6 or later.
BUILD FAILED

Uninstall everything java related and reinstall it then it should fix itself and compile properly.

erm... i uninstalled everything the tutorial installs and tried again and its the exact same issue.

to compile LWJGL you need some dependecies

sudo apt-get install libxcursor-dev # X cursor management library (development files)
sudo apt-get install libxxf86vm-dev # X11 XFree86 video mode extension library (development headers)
sudo apt-get install libxrandr-dev  # X11 RandR extension library (development headers)
sudo apt-get install libxt-dev      # X11 Toolkit Intrinsics library (development headers)

and you must edit the build.xml:
Before we compile, there is a bug in the LWJGL linux build that we need to fix first. In the file platform_build/linux_ant/build.xml you need to change this line (near the top):

<property name="libs32" value="-L/usr/X11R6/lib -L/usr/X11/lib -lm -lX11 -lXext -lXcursor -lXrandr -lXxf86vm -lpthread -L${java.home}/lib/i386 -ljawt" />
to be this instead: (just changing the i386 to aarch64)

<property name="libs32" value="-L/usr/X11R6/lib -L/usr/X11/lib -lm -lX11 -lXext -lXcursor -lXrandr -lXxf86vm -lpthread -L${java.home}/lib/aarch64 -ljawt" />
These are some compilation flags that ant passes to gcc when compiling.

do same to the next line "libs64"

The framerate is on the fly, the max is 40 fps most time it it is under 30 if you don't sudo jetson_clocks

problem is the compiler uses Buildfile: /home/switch/lwjgl/build.xml

and not what you pointed to.

No, you have to uninstall java (11?) and reinstall java 8. Follow
https://askubuntu.com/questions/84483/how-to-completely-uninstall-java
And restart the tutorial from the beginning.

Either I accidentally compiled with that change, or it isn't required with OP's compiling method.
I don't know if libx11-dev and xorg-dev contain the dependencies you mentioned, I probably had both.

you didnt show how to install java 8... the guide installs java 11
