So, I upgraded (finally!) from Ubuntu 10.10 to 11.04. I went and reinstalled Java, which had been uninstalled during the upgrade, but I was only able to get OpenJDK 6. Minecraft has been very slow and buggy (not letting me take screenshots or go fullscreen, massive visual glitches, etc.) so I uninstalled icetea and OpenJDK6 and installed Oracle Java 7 according to the instructions here. However, after I had moved all the appropriate files and created all the appropriate symbolic links, I found myself unable to open Minecraft, due to not having an application listed to open it with! Also, Java applets in my browser (Chrome) haven't been working either. If anyone with more tech knowledge than I have could assist me, I would much appreciate it.

Like what Intelli said, I am running Ubuntu 12.04 and OpenJDK 6 Runtime; Minecraft is running fine and hardly lagging for me (all though I usually have anywhere from 12 to 24 FPS running the standard version of Optifine).

Is there a reason you're sticking with such an old release of ubuntu?
Like Intelli said, 12.04LTS had the updated Java repos, things ran a lot smoother.

This doesn't directly answer your question, but you can mount your /home directory to its own partition, that way when you want to upgrade, you don't have to rely on their 'upgrade' script. If you want to install a new version, later you can just install ubuntu using the 'do something else' option. It's a bit more technical, but very worth it if you don't want to lose your files/settings.
