[enh] Need to sense docking station / switch video output

[Adrian Penisoara]

Binary package hint: hal-device-manager

I have a laptop which I'm daily changing it from docked (in the morning) and undocked (evening). My usual procedure is to suspend (standby) the laptop before docking/undocking.

When I do [docked]suspend+undock+resume or [undocked]suspend+dock+resume I don't get the video output switched automatically (and thus have no video displayed). I would need to press Fn+F7 or ScrollLock+F7 to trigger a video output switch (I am using intel xorg driver). However, my screen is automatically locked upon suspend so I first need to enter the password, but I cannot see the screen. Furthermore, on my Logitech keyboard hooked to the docking station I am unable to produce ScrollLock+F7 due to special function keys rearrangements.

I would need an enhancement like this:
 * somehow have the HAL daemon be notified of dock/undock status (or even status change)
 * once HAL daemon detected a docking change then it should trigger a video output switch by calling the appropriate xorg driver hook (if possible specify which is the current active video output).

I have a Toshiba T61 with an Intel 965GM GPU. I have to reboot after docking (laptop in suspended mode) because my LCD connected to the docking station doesn't work at all.
