So i recently moved to Ubuntu 12.04 and its really great however ive been having some problems with some games on Ubuntu, in this case it was minecraft, now originally it wasnt working due to java not working properly, then i followed the installer found here to get java working:
After this, minecraft was loading fine and i could successfully get into singleplayer and multiplayer games, however all of my textures were mucked up, like my arms were not there and my player skin was a culmination of block skins and stuff like that. I then deleted the .minecraft folder and re-downloaded the game and it worked perfectly.
I started to notice that i would get FPS lag in the game where usually when i was on windows i was fine. So i looked into my gfx card drivers, and they are ****** up. So i uninstalled all of the proprietary drivers and tried running minecraft without the propreitary drivers installed and now once i login, i hit a black screen and eventually a minecraft crash which gives me these errors:
i tried reinstalling the proprietary drivers both from the AMD site and through the "Additional Drivers" manager but still no luck.
Minecraft has crashed!
Minecraft has stopped running because it encountered a problem.
