black screen after swith intel graphic card

[kentyang]

I have a laptop(dell gaming 5577: intel i7-7700hq and nvidia gtx1050) and installed ubuntu 16.04.4 LTS, I installed non-free nvidia driver and intel mircocode. If I use nvidia graphic card, it is normal, but when I switch to intel graphic card thru prime, then logout, it will black screen and keyboard, mouse is no response, laptop should be crash. Reboot is same too. How should I solve it?
