I'm running Minecraft on Java 11 (openjdk) and on Linux machine (Ubuntu)

 

Vanilla works just fine, I downloaded the recommended forge 1.14.4 and installed it via the terminal without any issues. The game crashes after loading for a second. Not sure why? I downloaded the latest one after and it crashed too.

Any help would be appreciated!

 

No crash log folder for some reason but the latest log is as follows:

First of all thankyou so much for the quick response!

 

So do I download and run Java 10? How do I downgrade it? Or should I uninstall it and reinstall Java 10?

 

THanks again I've been working on this for hours

It finally worked! Thankyou so much. The installation was dodgy for me so I had to download JDK8 using:

 

    ~$ sudo apt install openjdk-8-jdk openjdk-8-jre

 

Followed by:

    ~$ update-java-alternatives --config java

 

Then select the java-8-openjdk-amd64/jre/bin/java from the list (to make java 8 the default, can switch and whatever but it works!!!)

 

Thanks a tonne!
