I'm full of shit, looking into it I realized that it's the other way around, LVDS was dropped in haswell while eDP has been around since sandybridge at least, certainly on the CF-52. Sorry! I hope I'm not adding to the confusion too much, but display #1 corresponds to the vga port on the machine, ie. an external monitor; display #2 would be LVDS, and #3 eDP/DPA. They're 0-indexed in the code, so it's 0, 1, and 2 when specifying them. The internal display should correspond to eDP in your case, so display #3 (2 in the code). IIRC the ',#N' syntax is also specific to vesa and not recognized by igfx (/sys/src/cmd/aux/vga/vesa.c:/^cracksize). I hope I've got that much correct and not telling more lies. Regardless, after you trying more or less everything, there's nothing much else to do but debug the actual code, so these traces or other random attempts will not help. I'd look into how displayport is setup in igfx and try to fix it. I need to do that as well, but as usual, no promises. Good luck! Hope that helps, qwx
