I have a laptop with both Intel and Nvidia graphics, running Ubuntu 18.04. I've installed and selected the proprietary Nvidia drivers via the Software & Updates GUI (the card is a GTX 1050, which Nouveau doesn't seem to support at all), and my system is happily running with the discrete GPU rendering everything, but obviously that's not exactly optimal in terms of battery life.
I've spent several hours trying to work out what I need to do to get hybrid graphics set up (i.e. the Intel iGPU drawing the desktop, but the Nvidia dGPU drawing GPU-intensive applications like games), but it seems like all the information I find is out-of-date or contradictory.
Is there an easy and supported way, in 2018, to use hybrid graphics on Linux?
