I have a ThinkPad P50 and Prime sync is now working for me. I don't know what change happened, sorry; it was two weeks since I did an update, and it could be an updated kernel or updated xserver packages from Timo's PPA. I have the 375 driver. And it works really well, it's marvellous to behold no tearing on the laptop panel.
