OK, so I think that these are not the HDMI/DP outputs connected to your secondary device. They are the ones connected to your primary device (might not be pinned out, or might only be available via an optional dock). Normally there'd be an extra -1- in the name of such outputs. But who knows with modesetting - perhaps it doesn't stick that in and sticks 100% to the kernel names. Have a look at https://nouveau.freedesktop.org/wiki/Optimus/ for some details on how to set up output offloading. The short version is that you want to do something like xrandr --setprovideroutputsource 1 0 If that doesn't help, grab the output of grep . /sys/class/drm/card*-*/status grep . /sys/class/drm/card*-*/modes preferably while something is plugged into one of your NVIDIA-attached connectors. When X first starts, it appears to get an EDID just fine for your secondary GPU's DP-1 output...
