Minecraft Forums

I am having what I believe is a java 6 and java 7 issues. I currently use Debian wheezy(linux) as my operating system. I use magic launcher to install modloader and the mod (I have tried two different ones with the same result). I tried using risugami's modloader, as well as forge. According to magic launcher everything was fine, till I tested it. the error said that It was using the wrong version of java. so I reset it so it was using java 7. but now minecraft itself wont run. black screen. Is there anything I can do to get it to run? It seems like alot of people are getting this same problem. The main mod I want to play right now is Skyforge.
