it looks like with -intel the xserver is connecting Configured Monitor to VGA output, not to LVDS:
+(II) intel(0): Output VGA using monitor section Configured Monitor +(II) intel(0): I2C bus "CRTDDC_A" initialized. +(II) intel(0): Output LVDS has no monitor section +(II) intel(0): I2C bus "LVDSDDC_C" initialized. +(II) intel(0): I2C device "LVDSDDC_C:ddc2" registered at address 0xA0. +(II) intel(0): I2C device "LVDSDDC_C:ddc2" removed.
However later in the log it sees that the VGA out is present but doesn't have anything connected to it.
