Can't run Blender any more

Hello!
I don’t know if this is the right place to ask, but I don’t know much elsewhere and here I knoiw everybody so I’ve got a question. Why I can’t run Blender any more? Today there was update for my Linux distro which:

  • Made little changes in Kernel, current Kernel for Ubuntu 15.04 is 3.19 AFAIK.
  • Updated NVIDIA video driver to 346.96
  • Some other small updates

May any of theese updates be the faulty?

Wait, I just have idea - computer haven’t been restarted since update although it required to be. Imma test it after restarting, lets finish watching hockey and than restart:D

Yes, I just had to restart. Yay - a bit better drivers out there:)
