I posted on the [Ubuntu Forums](http://ubuntuforums.org/showthread.php? t=1976246) but have had no luck so I thought I'd post on here.

After fiddling with Java and my graphics card drivers I eventually got minecraft to work. However I noticed that I was getting FPS lag in minecraft so I thought there was a problem with my graphics card drivers, I looked around and was told to install the proprietary drivers, so I did that initially from the "Additional Drivers" manager, after this, minecraft broke and wouldn't let me get passed the login screen, it would hit a black screen and then crash.

I then downloaded the (I think) binary drivers of off amd.com and followed instructions on how to install it from their "unofficial" wiki. After doing that I managed to get passed the black screen that minecraft produced but I was met with a minecraft crash error, the error I got was as follows:

      Minecraft has crashed!      
      ----------------------      

Minecraft has stopped running because it encountered a problem.

I have no idea how to solve my graphics card issue and would be much appreciated if someone could help me.

Have you tried running Minecraft with the OpenJDK? Its available in the Ubuntu Software-Center. Installing the Optifine Mod may also help you: http://www.minecraftforum.net/topic/249637-125-optifine-hd-a6-fps-boost-hd-textures-aa-af-and-more/
