I've been having trouble installing FTB onto my duel-boot Ubuntu computer. When I start the launcher with this command: java -jar FTB_Launcher it pulls up the launcher just fine, but when I start FTB Ultimate, for example, it shows the FTB animation then the log does this: http://pastebin.com/Nf7r9FkJ. Anyone know what's going wrong? I have Java 7 u17 Runtime Enviroment installed.
