Hi,
I've installed Nvidia 450 on new installation of Ubuntu 20.04.1.
Prime Render Offload works in manual mode with `__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia`
But nvidia-settings says prime is not supported.
And so I have no prime entry in the nvidia window.
So I think the swith between integrated and nvidia GPU will not be automatic and the "on demand" does not work.
I asked nvidia developpers and they said it should be a ubuntu patch :
