Unix Ubuntu 12.10 Launcher Crash

[Meldiron]

Yeah, i've seen a few unix gurus here, but they only come now and then so letting the thread age a bit is probably the best idea.
Unencrypted account name usualy indicates 1.0.3 or older, indicating there probably have been an unsuccessfull update which causes symptoms simular to what you described.
But seeing as i was mistaken will i leave this issue to the people who actually know what they are talking about and go repport the encryption bug

Hi I have Ubuntu 12.04 64-bit with the official Oracle Java 7 64-bit and I have it working. I have to install the latest LWJGL though or I get a white screen and it hangs.

This thread may help, it's someone with the exact same issue as you with vanilla minecraft and he solved it:
