That github tracker is ONLY for bugs that occur with OpenRM (the "Open GPU Kernel Module") but not with the the proprietary driver. If you have a bug with the the Nvidia proprietary driver, that must be reported on the Nvidia forum instead: https://forums.developer.nvidia.com/c/gpu-graphics/linux/148

So i need to move only the VGA output to > > seat1 and not all the outputs.(Note: I know nothing about multiseat, but I know something about nouveau.) What GPU is this? The fact that VGA is listed makes me think it's an older one. Pre-Kepler GPUs only support 2 CRTC's, which means you can only have 2 outputs enabled at a time -- this is a hardware limitation. So if this is a GFxxx or GTxxx in "lspci" (or even older, Gxx or NVxx), then this will never work with 3 outputs / seats. Also, I notice that you have a "fb" driver going, whose sole task is to display the same thing on all outputs. I don't know how this interacts with multiseat, but basically you have to ensure that you're in "graphics" mode, which I think makes it effectively disabled. But I've never used systemd, so I'm not completely sure how that interaction is brokered. Cheers, -ilia
