Nope, with fglrx 8.09 the backlight goes off perfectly. With radeon (xserver-xorg-video-ati 1.6.8.0-1 on ubuntu Hardy) the backlight does not go off. I can simulate it by pressing the lid button of my laptop. What happens is that my screen goes off (backlight is off for a sec or so and I don't see my desktop) for a second, then completely comes completely alive (i.e. I see my desktop etc) for less than half a second and then goes completely blank, but with the backlight on. After browsing a bit, I found a clue that there is something related to acpid.
Snippet of /var/log/acpid starting with pressing the button and releasing 5 seconds later: **** [Fri Oct 10 23:43:02 2008] received event "button/lid LID 00000080 00000025" [Fri Oct 10 23:43:02 2008] notifying client 5109[0:0] [Fri Oct 10 23:43:02 2008] notifying client 5995[107:116] [Fri Oct 10 23:43:02 2008] executing action "/etc/acpi/lid.sh" [Fri Oct 10 23:43:02 2008] BEGIN HANDLER MESSAGES ERROR: Couldn't attach to DCOP server!
