Two headline features of Fedora 25 are:

My laptop has a dual GPU setup (Skylake + GTX 970), but I can't seem to start a Wayland session at all. GDM even runs using Xorg, and the "GNOME" session logs in using Xorg.
I checked my initramfs, but it includes the drm module, as well as both kernel modules: nouveau.ko and i915.ko. From a console session, I can start weston (weston-launch), but I can't start gnome-shell (dbus- run- session -- gnome-shell --display-server --wayland). It errors with:
mutter-WARNING **: Can't initialize KMS backend: could not find drm kms device.
The Wayland session worked in F24, so I'm guessing this is because of the dual-GPU support enabled in F25. Should these two features be mutually exclusive? Should I expect wayland *or* GPU render offloading?
