Comment 2 for bug 1355884

After installing nvidia-prime, and before rebooting I ran:

sudo prime-select intel

and this problem went away for me.

I purged all bumblebee, nvidia, primus packages. I ran auto remove and did a dpkg -l | grep nvidia to make sure that no nvidia packages were installed. I then rebooted my box. After that I installed:

nvidia-prime nvidia-331

waited for the install to finish, and then I ran

sudo prime-select intel

It told me that it was updating alternatives. I then rebooted and the problem went away.
