Hei,
Also, many userspace applications can work with that. Mplayer (and
other mediaplayers) for example regularly sends events to keep
xscreensaver disabled, thus keeping everything like it should be while
watching a movie without manually disabling the behaviour. This, like
all the things raster mentioned, would be desirable to keep with the
dim feature.
Here is the answer. Enclosed is the second version the patch
implementing the backlight dimming. Contrary to the first version, it is
based on the screensaver extension but the dimming will only work when
the screensaver is activated.
Cheers Mathieu

Add automatic backlight dimming based on the screensaver extension.
