I have Lubuntu and Ubuntu partitions on my drive. I've been having an interesting time with the new lubuntu partition. I've encountered strange things with the game Minecraft, Java and graphics drivers on the lubuntu partition.

Firstly, I'll say that Minecraft runs fine at about 60fps on the Ubuntu partition with the latest drivers. (This is lower than it should be as it's a pretty decent graphics card [Radeon HD 5700].)

When I first started lubuntu, I tried to see if I could get Minecraft running on Java. Java crashed when loading the main game graphics on both Sun and OpenJDK without proprietary drivers.

Java also crashed on both Javas with proprietary drivers after the necessary restart. However, after disabling (with 'remove' button) the proprietary drivers with jockey-gtk in the session after the restart to install the drivers, Minecraft ran very well at ~120fps. This didn't continue after another restart, when it ran at 9fps.

After failing thereafter on lubuntu to get it working at >15fps, I tried reinstalling lubuntu and installed the exact same driver (the latest one, not the one appearing on jockey) and Java versions as on Ubuntu. That is, now Ubuntu and lubuntu have the same graphics driver and Java version. Minecraft still crashes in the same way on lubuntu but works fine on Ubuntu. I would appreciate any explanation for any of these events. What differences between lubuntu and Ubuntu could cause this?

Edit: After installing the 32bit driver version on lubuntu (seeing as lubuntu is 32bit), I have Java "working" for Minecraft. However, it is at <15fps again and it can't log in to servers as it takes too long.

  • What output does java -version show in terminal? – Axel Aug 16 '12 at 19:06

I had Lubuntu, and it ran Minecraft fine, and I only had openjdk 6 & 7, and a friennd of mine has the same setup (software-wise, not hardware) and he runs Minecraft a little worse, I think its all about the speed of your device.

Do your drivers work? Since I got an Radeon HD 6650M, but Lubuntu and Ubuntu just ignore it and run the game on my cpu.


I can't really help you but why don't you try to intall the Optifine Mod for Minecraft, it increases your fps a lot... http://www.minecraftforum.net/topic/249637-125-optifine-hd-a6-fps-boost-hd-textures-aa-af-and-more/ Hope it helps you as a temporary solution :/
