It turns out the kernel has no problem controlling the backlight, but as soon as the nvidia driver takes control it no longer work. With nouveau it works though it stops working after a suspend (the brightess is at its maximum after a resume and cannot be changed). Also, the hotkeys stops working after a while, but the backlight can still be controlled via the battery applet or the /sys/class/backlight/acpi_video0/brightness file (and, BTW, as I said before after a suspend it doesn't work, but the hotkeys are working again, i.e., they're changing the value in the file but it has no effect on the backlight). Still looking for a way to avoid for the disk to spin down when on battery. Bye -- Luca
