Comment 4 for bug 1663926

I have tested 17.04 preview and without de nvidia-prime I can boot and shutdown with intel gpu. When I install nvidia 378 with prime I can boot with the nvidia and I am able to do prime-select and close and start new session with intel and the same way around. BUt, if I shutdown the laptop with the intel selected then it won't boot again, I have to start a recovery session and do prime-select nvidia (sometimes more than once) to be able to boot again.
