edit:
A crude work around for the lack of backlight control is to boot into osx, crank the brightness, then reboot. The brightness will stay cranked.
Has anyone booting via the EFI/grub2 route using using the Intel gfx only (via outb commands) have external monitors working?
xrandr shows the monitor is connected and detects the resolutions, but does not drive the display. It seems like when I enable the external monitor (DP1) it's display is being sent to the LCD (LVDS1). Below is my xrandr output:
