I think I've hit basically the same problem Oleksij is reporting (blank
eDP) when using the ASUS UX31E with an external HDMI monitor and leaving
it plugged in while booting
(https://bugzilla.redhat.com/show_bug.cgi?id=844985).
Aside from the fact Oleksij uses VGA and I use HDMI, it otherwise seems
to be the same issue.
I ended up finding this bug report because one of the patches attached
to this bug while searching for the bad panel power sequencing delays,
disabling panel error message I found in dmesg.
I'm also still seeing the problem Bryce described way back in the original bug
report: if I use Fn+F8 to disable the internal LCD, it doesn't come back unless
I do a mode change on the internal monitor. That seems to be a very different
problem though, as in that case eDP1 still shows up in the xrandr output.
