Backlight stays lit

Bug Description

Binary package hint: gnome

When the machine is left alone then the screen will display black, however the backlight will remain lit for a considerable amount of time there after. An easy way to check is by putting the machine in a totally dark room, the screen should not be glowing. This is a bug because its not Green. Global warming is a very serious threat and I wish Canonical would do more to help.

Peace

Thank you for taking the time to make ubuntu better.
In Preferences > Power Manager you can select the display time, for instance on my jaunty system I set mine to the lowest - 11mins and after that time it shuts off power to the monitor completely.
The solution to this issue I believe is to wishlist that the default setting be less than 40mins which it currently is, so will not show a black screen for a long period of time.
Cheers

I fail to see the point of a screen saver that is attempting to display a
perfectly black, but instead displays a grey screen which is waisting the
life, using Co2, eating up my battery and burning out my display.

Setting to Wishlist on behalf of Kurt [trinikrono] since this is requesting a change in the default settings.

I thin its funny that wanting Ubuntu to not rape the environment and my
battery is a "wish list" item. Clearly there is a problem with Canonical's
view of their impact.
