Re: [PATCH] drm/i915: set LVDS connector status to unknown if the lid is closed

Currently, the LVDS connector on i915-equipped laptops is always reported as connected, regardless of the lid state and presence of external monitors. This was done because of too many BIOSes reporting lid status in an unreliable way. However, in a quite usual setup of a laptop attached to an external monitor, the only way to obtain the monitor's resolution on boot is to disable the LVDS via the boot command line, which is unfortunate as one have to reboot to get the internal screen back.

If ACPI lid status were even remotely reliable for Intel machines, this might be a good idea.
