Loading problem at startup

[dante]

When I start up Minecraft and login, the "Hello" window pops up and does nothing, just sits there with "Currently doing...". No error log either. I'm using Ubuntu 12.04, if that helps.

If a "Hello" window popped up, there should already be logs...look for something like ForgeModLoader-client-0.log in your .minecraft.
