Let me start off by saying that I have scoured the forums for answers before creating this, and that I have read the rules. I also didn't use both editions at the same time.

Anyway...

I have been trying to install FML for Minecraft 1.5, and *obviously* I have been getting the black screen. I've tried both editions of FML, all with the same symptoms. I have tried deleting everything FML downloaded in the lib folder, I have tried deleting META-INF, and I have tried not deleting META-INF.

 

This is with a fresh copy of Minecraft 1.5, with no mods installed in the mods folder or in the minecraft.jar .

Also, here's a log from ForgeModLoader-client-0.log since that seems to be a requirement.

Any and all help will be greatly appreciated.

Thank you.

Note: I'm running Debian Wheezy 7.0 GNU/Linux with an Oracle Java installation. I have tried running Minecraft & Forge with OpenJDK and it has yielded the same results.

Use a compatible launcher.
