    Numbat, Kubuntu, and I think openjdk

    My issue I'm sure is my knowledge of Linux GUIs. Lots of experience server-side, but all cli.
    Fresh install of 24.04 Kubuntu. Trying to run a jar file. Ran with no effort on 22.04 GNOME. Installed openjdk app and openjdk-11, right-click the jar, runwith that, all good.
    The jar file in question is a sites' custom modded Minecraft launcher
    On this build however, not so good. I can manage to start the launcher in Konsole (java -jar filename.jar) then tries but can't actually launch any of the options.

    Other apps run just fine, even Steam.
    Thanks for looking.

    Re: Numbat, Kubuntu, and I think openjdk

    It seems like you're encountering issues with running a custom modded Minecraft launcher jar file on a fresh install of Kubuntu 24.04, despite it working fine on GNOME in Kubuntu 22.04. Here are some steps and considerations that might help you troubleshoot and resolve this issue:

    Check Java Version Compatibility
    - If the versions differ, try installing the exact version you had on 22.04. For example, if it was OpenJDK 11, install it with:

    sudo apt-get install openjdk-11-jdk

    If it doesn't work, try it reinstall Java

    sudo apt-get remove --purge openjdk-11-jdk
    sudo apt-get install openjdk-11-jdk
