Hmmm well if the display isn't fakaked, which is actually surprisingly infrequent (i.e. it is fakaked), via EDID it should inform the OS (if it asks) what the orientation is so the OS can just do the right thing. I have a display in a box about 20 feet away that does the right thing. Maybe....hmmm....MAYbE I should get it outta the box? And I don't know, test it? Egads. I know it works on X, but ONLY with the discrete GPU. Integrated GPU, no go.
These are desktop displays. They don't know which way up they are, they can't tell the OS.
Yeah I'm talking about desktop displays that pivot, either landscape or portrait. Any display, pivoting or fixed, is supposed to be able to communicate it's h and v resolution and hence orientation. As far as I know, the fixed ones all communicate this correctly. The pivoting ones don't always do that, or it could be a graphics card or driver or window server miscommunication.
I'm not sure if it communicates via EDID or DDCI, but it definitely communicates it via either a DVI, mDP or adapter connection because all I do on OS X is pivot this display the way I want and the OS changes the signal it sends. There's no UI for this on OS X either. So the lack of UI in GNOME doesn't tell me if it'll work out bit with Wayland.
