[Problem]
On an Acer TravelMate 6292 the LVDS does not get disabled when the lid is closed.

[Original Report]
With Kernel 2.6.30, things have improved and everything was almost fine :
 - External display is set up with the correct resolution.
 - The laptop panel (LVDS) is enabled (even when the lid is closed) and is also set up with the correct resolution.
But :
 - the laptop panel (LVDS) is enabled even when the lid is closed.
 - both monitor display the same things (clone mode).

Today, kernel 2.6.31 break everything : My external monitor is no longer recognized.
I follow Karmic evolution and I will watch if things get back into shape.

Here is my setup :
My laptop is an Acer TravelMate 6292 with an integrated graphics chipset INTEL 965GM.
It is docked in an ACER docking station
An external LCD monitor is plugged on the docking station (using the VGA connector).
The laptop's lid is generally closed.

With this setup, the external monitor is set up by X with a 1024x768 resolution whereas the preferred one is 1280x1024.
The laptop panel (LVDS) is enabled (even when the lid is closed) and is also set up ith a 1024x768 resolution whereas the preferred one is 1280x800.
Both monitor display the same things (clone mode).

Expected behaviour :
When the lid is closed, the LVDS panel should be disabled and the external monitor should be set up with its preferred resolution.

If I use the DVI connector of the docking station the behaviour is exactly the same.
