Nvidia reverse prime issues

I'm having some pains with my laptop (Gigabyte Aero 15) that has an intel integrated gpu and an nvidia gtx 1060 discrete gpu.
I need to plug a screen into my hdmi port (assumed to be connected to the dgpu) but it won't show up in xrandr. nvidia-settings shows that the dgpu recognizes the screen connected since it's listed there.
I can run programs on the dgpu

xrandr -q (prime-run xrandr -q returns the same thing)

pastebin

glxinfo | grep "OpenGL renderer"

OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 630 (Kaby Lake GT2)

prime-run glxinfo | grep "OpenGL renderer"

OpenGL renderer string: GeForce GTX 1060/PCIe/SSE2

I've tried reverse prime as listed here but the following anarchy ensues:

xrandr --setprovideroutputsource NVIDIA-G0 modesetting

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  35 (RRSetProviderOutputSource)
  Value in failed request:  0x23f
  Serial number of failed request:  16
  Current serial number in output stream:  17

Help appreciated greatly

Re: Nvidia reverse prime issues

You can't use prime-run with external screens, you'll need to set up one of the more traditional approaches.

https://wiki.archlinux.org/index.php/NVIDIA_Optimus (all of the nvidia using options should work, to verify basic functionality, follow the "Nvidia Graphics Only" section (and remove nvidia-prime the configs directly conflict)
