". i tried to get this fixed and the people on the minecraft help forums told me that this is because since my computer is a piece of crap, that ubuntu doesnt support the graphics card. im on a dell dimension 2400. its old. haha so i was wondering if there was any way to fix this, i really want to be able to play minecraft again. i tried loading it through wine, but it returns an error saying i need a java platform, so i am guessing i need to install java directly to wine? how would i do this if i need to. also would that even fix the issue? or would i just be wasting my time? if anyone could help id really appreciate it. thanks in advance!



update: i just found out, the dell dimension doesnt use a graphics card, it has integrated Intel 3D Extreme Graphics on the motherboard dont really know what that is, kind of a beginner with coding and everything.
