nativeVr reports HMD present when none connected

[sidequestlegend]

is there a way to force "2D" mode? Like say I just have Steam VR installed, can i launch an aframe example without it trying to present to the VRDisplay? Can i utilize the FakeVRDisplay located here for that somhow?

https://github.com/webmixedreality/exokit/blob/master/src/core.js#L28

currently i'm getting:

Hm, I think if there is no HMD connected OpenVR should have said so here. And therefore the vrdisplayactivate shouldn't have been emitted.

Does this mean OpenVR is saying there is a display connected and then erroring because it isn't?

To more directly answer the question, I think you should be able to disable VR support with -x none. But if OpenVR is misdetecting it might try to boot it anyway.

Yep that check is passing i.e nativeVr.VR_IsHmdPresent() === true when i have no HMD connected and Steam VR says Not Ready. The -x switch works well though!
