[Bug 57101] ibook default settings: screensaver turns backlight back on

[tjr]

Public bug reported:

Binary package hint: gnome-screensaver

Hi,
with everything left to default settings since install, (presumably) the screensaver turns on the backlight even after I manually switch it off. 

 xset dpms force off ; sleep 3 ; gnome-screensaver-command --activate
(and its brightness key equivalent) will result in a blank screen and backlight turning on after 3 seconds, regardless of battery or AC, so it is indeed the screensaver in the short run. If I simply turn down the screen brightness to off while on AC and come back 8 hours later, I see bright screensaver images (no blank screen). I have not yet dug into that case, but strongly suspect gnome-screensaver to be the culprit, too.

While there are lots of other bugs filed on backlight issues, this one
is about default preferences. I would expect any kind of
timeout/powermanagement/screensaver never to turn the backlight back on.
Even better, to turn it off after a while.

hardware: ibook G4 1 Mhz,
0000:00:10.0 VGA compatible controller: ATI Technologies Inc M9+ 5C63 [Radeon Mobility 9200 (AGP)] (rev 01)

install: breezy dvd, then apt-get dist-upgrade; tinkering with airport
express, wpa and few other things, but nothing related.

Thank you.


edit: maybe I should have filed 2 separate bug reports:
* please make the backlight go off by default (at least after 8 hours)
* please make gnome-screensaver never turn the backlight back on

Sorry, I don't know how to split it...
