Blender does not start

Hi,

i uses Ubuntu 12.04.1 LTS, and have used blender with no problems. But for four days it does not start anymore, and I just don’t know why. I have to start it with the help of the terminal, but it just shows me some informations i don’t understand. Does anyone know what I should do to fix this?

I’m following to hear from you.

Yours sincerely
Greenality
