Minecraft on Ubuntu

[tomk11]

I've just paid for and downloaded minecraft on ubuntu 11.04. However, when Iog in, the screen goes black for a few seconds, then the error below pops up. If I force update, it updates, then the same thing happens.

I'm pretty certain that java is up to date because I just downloaded it from the software center so I could open with 'sun java 6 runtime'.

Edit: I thought that maybe running an older version of minecraft might solve the problem, but after a quick google the only hits I could find required knowing someone with a previous version, or having previously had an older version installed.

Okay, so from the java website I see I can install from command prompt. at http://www.oracle.com/technetwork/java/javase/install-linux-self-extracting-142296.html in step 3 it asks me to change directory to where I want to install it. Apologies for my ignorance but where would be a good place to change directories to?

 

[tomk11]

I'm trying to play on a advent 5301 which doesn't have a dedicated graphics card - I can't see how minecraft can be graphics intensive though?

 

[tomk11]

It's not that it's intensive, it's more along the lines that you probably have no hardware acceleration.

Open up a terminal and type in glxinfo | grep direct and post the result here. lspci and lsmod output would be nice too.

Copied and pasted from the Terminal.

tom@tom-DIXONSXP:~$ glxinfo | grep direct
direct rendering: Yes

I've never been able to understand graphics cards... any recommendations of a particular card? sorry about my stupidity...

 

[tomk11]

Ok, thanks for the help, at least now I know why it won't work and can just leave it in peace. When I finally get a new laptop I'll remember to get one with a dedicated graphics card then.

 

[tomk11]

Didn't see post #11 sorry, just tried
