Launching an environment (DE) or a window manager (mutter) on DRI_PRIME (i.e. AMD)?

Question

ubuntu

I have a laptop with intel hd 3000 and amd 7670m graphics, amdgpu does not support, but DRI_PRIME=1 works, I try to run Gnome on an Amd card, otherwise it slows down on Intel Gnome (there is no animation smoothness), I don’t want to turn it off
