Questions[minecraft](ubuntu)

I have ripped the web up trying to figure this out. Bumblebee hasn't helped. I want to run Minecraft on the Nvidia GPU in my laptop. As far as I can tell, Ubuntu default runs it with Intel because Minecraft runs inside of Java, which, obviously, is not generally GPU intensive. I'm using Bionic Beaver, and the optirun command is broken. It throws an error that the nvidia-fallback.service is disabled, but trying to enable it reveals that the file doesn't exist. As far as I can tell, this is a Bionic Beaver problem. The primusrun command seems to work, but now I can't make it run Minecraft specifically. I feel like the problem could be fixed with an Nvidia application profile for Java runtime, but I don't understand the documentation on Nvidia's website. If someone can just post a rule key that forces an application to use Nvidia (and actually works; I found one, but it's "not recognized"), that would be great.

if I missed any specs, please tell me, I'm new to posting questions.

Mojang recommends using Oracle's JRE, but I see people using OpenJDK all the time. What are the advantages and disadvantages to using one or the other on Ubuntu, either in general or specifically as it relates to Minecraft?

How to correctly install Minecraft, including setting any needed packages or apps to install it and to troubleshoot the most common problems that Ubuntu users face when trying to use Minecraft.

I am trying to install and run Minecraft without first having to install the Oracle version of Java. I want to use the OpenJDK version that comes with Ubuntu and as a last resort, use the Oracle one.

I also want to know a list of problems related to Minecraft in Ubuntu and the possible solutions to them.

A step by step guide on how to install Minecraft would also help.

Please anyone can help me with this? I think that problem will be in architecture becase:

liblwjgl.so: /home/zrebec/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

Any idea please?

I know, maybe this one is off topic because maybe its not Ubuntu problem maybe but in 64-bit works all perfectly and I think that accepted answer can help to many users and can make better playing games under linux. Really. Thank you very much for any idea.

I have tried many tutorials but none of them are clear enough. I have also tried installing it using Wine but it won't update and Wine goes gray and stops working.

Does anybody know an easy way to install Minecraft though the Java file without using Wine?
