I don't see the andwer n the questions above. What I find working is putting nouveau.modeset=0 on kernel command line. I check by: $ xrandr --listproviders Providers: number : 1 Provider 0: id: 0x4c cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 10 associated providers: 0 name:modesetting

How to check whether the card is really powered off, I'm not sure though. Needs further investigation.
