Error trying to launch Tekkit Legends with custom script.

[Xrey274]

I'm on Linux. In order to disable v-sync I need to add 'vblank_mode=0' before calling java. Only way to do this is to launch Tekkit Legends without relying on Technic Launcher. I used Technic's console to see what command it uses to call Tekkit Legends and I just copied it and added 'vblank_mode=0' infront of it. For whatever reason it error's out and I have no idea why. Help would be appreciated.
