Minecraft error on startup

[Uniplex]

Hiya!
I just got Ubuntu, so when I installed Minecraft at first it worked fine; but when I tried again a bit later, this error was thrown up on startup: (I started it from the terminal)

If someone could help me, that'd be great

Also, I used the command

java -jar minecraft.jar

to start it.

[entw]

First update your lwjgl. As you can see here actual version is 2.8.5.

[entw]

~/.minecraft/bin
./natives/
    libjinput-linux.so
    liblwjgl.so
    libopenal.so
jinput.jar
lwjgl.jar
lwjgl_util.jar

These are the files you need to replace. Also tell us your java version (you can use the following command: java -version).

Replaced all the files, but I'm still getting an error. This time I copy-pasted it from the crash-reports text file:

Also, I'm running OpenJDK 6.

[holastickboy]

Also, I'm running OpenJDK 6.

First things first, please install Oracle Java, particularly Java 7 for Minecraft and other Java games.

I have made a simple tutorial for Ubuntu 12.04, but this also works with 12.10 (which is what I am running now).

Have you tried re-installing it? To do that, go to your home folder, and do Ctrl+H. Look for the folder called ".minecraft". Just delete it, then run the Minecraft.jar file that you downloaded from minecraft.net.

Replaced all the files, but I'm still getting an error

Oh, you need also x64 libraries, which are present in lwjgl zip-package. Forgot to mention that after replacing of lwjgl files you must restart your X-session.

I was using Open JDK 6 and getting the same error as the OP. I've been trying all day to get minecraft working for my son, but after entering the login and password, it would crash and give me a crash report that cited lwgjl as the problem. I installed Oracle 7 as recommended above, and now all I get after login is a black screen. I'm running ubuntu 12.04, and I'm out of ideas. Please help!
