[Pkg-utopia-maintainers] Bug#466679: hal: D420 laptop does not power off backlight on AC+docked with default BIOS settings

[Tim Richardson]

Package: hal
Version: 0.5.10-5
Severity: normal

My Dell D420 does not turn off the screen when it is on AC AND docked to 
the media base AND the BIOS settings regarding priority of video card 
are default.

docked and on battery: it works.
undocked and on AC, it works.
There is an easy  fix. 
To fix it, change the BIOS setting to use onboard video.
The media-base is a mini-docking station and does not have a video card, 
but it does enable an external monitor using DVI to be attached.

I guess this is linked to HAL. 

I wanted to document it somewhere 
because other Dell D420 users may come across it.
