I don't see any occurrence of video=VGA-1:d in the loader config. Moreover, I
did test with VGA enabled in which case I got image on both outputs. This is
what I have:

boot/loader/loader.conf:

# Generated by setup-gummiboot-conf
timeout 0
default vmlinuz-3.13.3-17.2-x86-ivi

boot/loader/entries/vmlinuz-3.13.3-17.2-x86-ivi.conf:

# Generated by setup-gummiboot-conf
title Tizen 3.0.0 (Tizen Next)
version 3.13.3-17.2-x86-ivi
efi /vmlinuz-3.13.3-17.2-x86-ivi
options rootwait rootfstype=ext4 quiet
root=PARTUUID=23DADB8A-B065-480E-8BFC-94D7548D5B52


I wonder if this could be a link training issue with a specific monitor. I only
tested with the monitor I have on my desk.
