Only the second screen is active during boot (Intel VGA)

I have a Acer Aspire 5750z laptop with an Intel graphics card. I have installed xf86-video-intel and I have enabled early modesetting according to the information in wiki.

However when I boot my laptop if I have a second monitor connected, My laptop monitor would be blank until I enter X and everything would only be printed on my second monitor. even when I'm inside X if I change to another TTY, my laptop monitor is still disabled.

It was working alright until I decided to reinstall arch and now I can't seem to find how I can fix this.

Here are some information:

$ lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

# cat /sys/module/i915/parameters/modeset
1

This is the MODULES line in /etc/mkinitcpio.conf

MODULES="intel_agp i915"

Is the laptop screen active before linux starts ?

If yes, at which point does it get blanked ?
