Can't get Minecraft to run on Ubuntu
Since downgrading to an older release of Ubuntu won't solve the problem for this version, I try to fix it this way. It is basically this guy's problem but with a little difference: Minecraft goes black on 12.04
Upgrading LWJGL does not work, as they are "already updated" in Minecraft 1.3. I think that other users of EEE901 have the same problem. I will still downgrade to other versions because it might be reasonable to try the Java JRE 6 trick. I will keep track on this thread on another computer meanwhile.
