I've used the COPR repository here to cut down on my compilation time: https://copr.fedorainfracloud.org/coprs/firstyear/kernel-mbp/ I'm not certain how to test out your changes, or what the consequences should be on a stock Fedora 23/GNOME 3.18 installation. After booting (note that I did not change any command-line options in grub), a gnome-shell/gdm X11 session comes up (I disabled Wayland, to rule out behavioural changes), I'd log in to GNOME and gnome-shell (which starts another X11 session on another VT). I did not use any external screens to test this. >From a terminal there, I can see that both the integrated and discrete GPUs are turned on, and I believe that the HDMI audio on the AMD/ATI card is also powered on. I've seen that the patch is now queued for 4.6, and was wondering what changes would be necessary to make sure that only the integrated card is used by default, and the discrete GPU only used when the VGA switcheroo is actually enabled (or maybe through DRI_PRIME=1?)
