This is true, I have one of the first P51 models and it used to have threewi options in the BIOS 1) integrated, 2) hybrid and 3) discrete. With integrated mode everything worked like a dream, also the HDMI output. But after I got some serious problems after an year with the internal display (when powered up the display got distorted after few minutes), lenovo service changed the motherboard and after that there was only two options left in the BIOS (hybrid and discrete). Also the HDMI connector does not work anymore :( Lähetetty Jolla Sailfish -älypuhelimestani.

On older laptop models, one could select among integrated, hybrid and discrete. For many of us, selecting integrated graphics was the most stable option. On more recent optimus laptops, integrated is no longer an option, you can only select between hybrid and discrete. I believe this limitation is due to how the signal routing now requires some level of firmware support in the discrete chipset to get video out. In any case, hybrid has always (nearly?) impossible to get working under Xen/Qubes...so the next best option has been making discrete work.
