I just downloaded Minecraft on Ubuntu 12.04 lts. The launcher opens, but when I click play, it crashes and reopens with this error report.

How can I fix the error?

On Mageia 5 I just installed xrandr and ran it and it fix the problem. I don't know if by running it something was configured. But it works.
