I've googled around and tried what i could but i've come up empty, im a fairly new Linux user , so i wont be surprised if i forgot to install something or missed something somewhere, any help is very apreciated.

I'm tapping into the not so secret resource that is my hubby:
He asks-Do you have any problems with any other Java based programs?
(He can't be bothered to log in to his own account... >.> )
He continues to ask: why did you switch from 32 bit windows to 64 bit ubuntu? Do you have a 32 bit processor or 64 bit?

 

[Nopego]

Well, i solved the problem after more scavenging on the Internet, and figured out it was the lwjgl that had to be updated. Also my processor supports 32 and 64 bit, was just stuck with windows 32 until i had the idea of installing a free 64 bit OS, Ubuntu. Thank you anyway for the support, Now enjoying Feed the beast with my new OS, and freed ram.

Also my processor supports 32 and 64 bit

Just an FYI, this means your processor is 64 bit.
