Actually, Im trying to power up the laptop with the dock.. which since it has a power button its made for that. But leaving teh lid shut and just using the two external monitors. You can do that with Windows.. I'd want to suspect that with a superior OS this should be possible too.Something has changed and replies don't automatically go to the list anymore...

This morning I had some time spent trying to get my Dell XPS 13
9550 to output to three displays. Using the thunderbolt/USB-C
Dell 3100 dock, and HDMI cable/monitor and a DP to
mini-DP/monitor. But my question is, during this fight, I
attempts to run the laptop with the lid shut. Outputting to the
two external displays, powered up by power button on the dock. Long story short it did not work.. but what's weird is that I
raised the lid ever so slightly and could tell that it was on.
Now if the system senses the lid when it shuts to suspend.. why
not in this case? Could this have anything to do with the
hybrid graphics?
It's not clear to me what you're trying to do. Are you trying to
get the laptop screen to turn off when you close the lid, but keep
the other two monitors on? I don't think that's a supported option
(other than manually turning it off in the control panel).
If you set the monitor configuration to have the two external monitors on and the laptop screen off, what happens when you push the power button on the dock? Hybrid graphics cause a lot of problems, so that could be an issue as well.

Sorry for the reply snafu.
Let me toss in a related question then.. would disabling either of the graphics adapters help matters possibly? I am about to begin looking into that also.. But to answer your question, I don't know. I guess I was afraid of it not registering when off the dock and then for some reason not sending display to the laptop screen. But I will definitely try that at the end of the day.
