When the DP screen doesn't light up

Hey Ben,

Oddly-enough, my DP screen at work does not want to light up after a cold boot
but works if I reboot right away.

As I told you before, this screen is weird when it comes to coming back from
sleep mode.

The DVI screen lights up correctly but I doubt this issue is related to dual
screen because I tried unplugging the DVI screen a while ago to investigate the
resume issue and it didn't help.

I attached to the bug the kernel logs with 
nouveau.debug="PDISP=trace,I2C=trace,VBIOS=trace" for both the case when the
screen doesn't light up and when it does.
