How to play a Game with Commands Environment?

So now i have a very old laptops. Only having 2 GB ram. And i really wanted to play Minecraft (Java). But whenever i play it, its always dropping to 20-30 fps somehow (In Bodhi, and Q4OS Trinity. And i think the DE can affect this. So i have an idea to play Minecraft without installing any DE or application. Just the core, drivers, and minecraft, nothing else. But idk is it possible or not. Or i should install DE to provide a GUI? The game it self use .jar so i think its possible. But idk, maybe someone could explain me? Thank you very much for answering :)
