Hi, VGA switcheroo doesn't work on my 2013 MBP, and I'm trying to fix it. From what I've gathered from previous patches, it seems that the EDID is not computed at boottime, because LVDS isn't connected to the i915 card (and is connected to the nouveau card instead). So, here's a series to get switcheroo-reprobe to call get-edid. I think it's a step in the right direction, although I think more stuff is required to fix the issue.
Disclaimer: The series might be utter rubbish, because this is my first attempt at any driver code. Thanks.
