This would seem to be the root of your problem, I have the following:

(II) intel(0): Output configuration:
(II) intel(0):   Pipe A is on
(II) intel(0):   Display plane A is now enabled and connected to pipe A.
(II) intel(0):   Output VGA is connected to pipe none
(II) intel(0):   Output TMDS is connected to pipe A

Further up in the log there should be a section where the monitor
detection happens. Mine looks like this:

(II) intel(0): Integrated Graphics Chipset: Intel(R) 845G
(--) intel(0): Chipset: "845G"

What do you have?
