Minecraft Forums

I have been trying to run Minecraft on my Ubuntu 12.10 partition now for the past few days but every time I try to sign in I get a black screen right after. I have followed other instructions on updating the lwjgl files along with the native files then adding new ones and even deleting the .minecraft folder and then rerunning the Minecraft.jar file and nothing seems to be working. Recently I tried running the .jar from the Terminal and I got this exception:

I was wondering if anyone might know how to solve this issue as all the other solutions have not been working for me. I am using the Oracle Java 7 Runtime when I try to run the .jar normally.

System stats:
OS: Ubuntu 12.10
Processor: Intel Core i5
RAM: 8GB
HDD space: approx. 175GB for Ubuntu Partition

I have determined the cause of my dilemma. It seems I tried using an older version of the lwjgl files by accident. I was using the lwjgl version 2.5 instead of the newest lwjgl version 2.8.5.
