Answer 1

You first have to uninstall JOGL from the packet manager if you have already installed it. Then in your project you have to add the necessary libraries to the build path. If you are using maven add this to your dependencies:

<dependencies>
    <dependency>
        <groupId>org.jogamp.jogl</groupId>
        <artifactId>jogl-all-main</artifactId>
        <version>${jogl-version}</version>
    </dependency>

    <dependency>
        <groupId>org.jogamp.gluegen</groupId>
        <artifactId>gluegen-rt-main</artifactId>
        <version>${jogl-version}</version>
    </dependency>
</dependencies>

Where ${jogl-version} is property defining the JOGL version. You can either use the property or hard-code the version you want to use:

<properties>
    <jogl-version>2.2.1</jogl-version>
</properties>

If you are not using maven you should follow the steps from the project's wiki page: https://jogamp.org/wiki/index.php/Setting_up_a_JogAmp_project_in_your_favorite_IDE

Please uninstall any JOGL package and follow the official instructions available here and the instructions for the IDEs here.

I have used JOGL under GNU Linux since 2006 without any trouble. Good luck.
