I don't think it is a kernel thing.

In any case, I've updated my kernel over CentOs to the last version : vmlinuz-2.6.32-358.2.1.el6.i686 ant the same results. ( log is attached )

I've also tested other enviroments with newer kernels and happen the same:

Fedora Core 17 i686 : xorg-x11-drv-intel 2.19.0-1 / kernel 3.3.4-5
Fedora Core 18 i686 : xorg-x11-drv-intel 2.20.19-2 / kernel 3.6.10-4

It happesns the same : LVDS1 repostes as disconnect on plug an VGA monitos

Also the vesa driver shows on LVDS1 and VGA1 a perfectly cloned desktop. Without disconnect LVDS1 display. Unlikely for oue propouses vesa driver is a very basic one, no extended desktop included.

I wanna focus on the hardware : is a Panel PC, not a laptop!! and acpi even don't create /proc/acpi/button/lid directory! this is why I think there is some problem into the understanding between ACAPI and Inter Driver. Intel drives could not report the right lid status and LVDS1 is disconnected by the drives when other option like VGA is available.
