My laptop is able to dim it's screen automatically until it is turned off by Ubuntu to save power, currently my dim screen button doesn't let me turn off my screen completely, my questions are:

  • Is it possible to configure the 'dim screen' button on a keyboard to dim the screen until it turns off or is this limited by hardware? (I don't think that it would be limited because it can turn itself off automatically with my operating system, so why not through a key-press)

  • If it is possible has someone done it or has someone got an idea of how to do it? And could they please explain it below?

If it comes in handy here's some potentially useful laptop information:

Model: HP Pavillion DV6000
Graphics Card: Intel Corporation Mobile 945GM/GMS
Memory: 2Gb Ram
OS Currently Installed: Ubuntu 12.04 single-boot

Edit: As suggested by the user Cumulus007 below it might be hard-coded into my hardware and not modifiable, if anyone could confirm this or find a justification for the opposite I'd be very grateful.

Take a look at this link.It works for me. –  RanRag Jul 19 '12 at 10:51
    
It works, but however I want to be able to gradually dim the screen and then turn it off, this turns my 'Dim screen' button into a 'turn off screen' button unfortunately. Any ideas otherwise? –  Oyibo Jul 20 '12 at 14:57
    
I think the screen dimming interval is hard-coded into either the ACPI table or the screen controller. –  Cumulus007 Jul 21 '12 at 20:41
    
@Cumulus007 if you could type up your comment with sources confirming it, I'll gladly accept it as an answer :) –  Oyibo Jan 10 '13 at 15:19
