@Stefan Bader
I'm glad to inform you that now brightness *DO* react to brightnessup and
brightnessdown scripts (/etc/acpi/video_*
) and seems fixed. The second check was the problem, definitely =).
Also "brightness gnome applet" and "brightness gnome control" (as gnome panel
add-on) wok well.
Btw, there is a secondary issue with FN keys. Even if brightness reacts well to
scripts, FN+keys seem broken. Let me explain what happens:
[Initial status of the machine is BRIGHTNESS_MAX]
If I press FN+BRIGHTNESS_DOWN just once
> It increases (correctly) to BRIGHTNESS_MAX-1 but then *immediately*
goes to BRIGHTNESS_MIN (wrong)
[Initial status of the machine is BRIGHTNESS_MIN]
If I press FN + BRIGHTNESS_UP just once
> It increases to BRIGHTNESS_MAX+1 (correctly) but then immediately
increases again, so finally it goes to BRIGHTNESS_MAX+2 (wrong)
If I press FN + BRIGHTNESS_UP again
> It returns to BRIGHTNESS_MAX+1 (wrong)
The only way to increase brightness with the FN keys it's to keep
FN+BRIGHTNESS_UP pressed for long, so that in the end it raises
BRIGHTNESS_MAX level.
It's like if there's a wrong mapping with the keys or, worse, a wrong
key event management. Anyway it has no link with the main issue, which
seems completely solved.
