I don't know why, but acpid need restarted every time that I power on the laptop, if I don't do that, the brightness don't work :S
I'm trying and I see that Ubuntu don't use: /usr/lib/hal/scripts/linux/hal-system-lcd-set-brightness-linux and /usr/lib/hal/scripts/linux/hal-system-lcd-get-brightness-linux For nothing in sony-nvidia Only use: /etc/acpi/events/sony-brightness-down /etc/acpi/events/sony-brightness-up That are the only files that apply changes to brightness. If any one know why, please tell me why ubuntu don't use this /usr/lib/hal/scripts/linux/hal-system-lcd-*-brightness-linux with vaio- nvidia config. And one more thing, in my comment https://bugs.launchpad.net/ubuntu/+source/hotkey- setup/+bug/95444/comments/106 I correct one thing: change: elif [ "$HAL_PROP_LAPTOP_PANEL_ACCESS_METHOD" = "sony-nvidia" ]; then # smartdimmer -g # value=$(( `smartdimmer -g | awk '{print $3;}'` -2 )) value=$(( `nvclock -S +0 | grep level: | awk '{print $4;}' | sed -e 's:%::'` / 5 -3 )) to elif [ "$HAL_PROP_LAPTOP_PANEL_ACCESS_METHOD" = "sony-nvidia" ]; then # smartdimmer -g # value=$(( `smartdimmer -g | awk '{print $3;}'` -2 )) value=$(( `nvclock -S +0 | grep level: | awk '{print $4;}' | sed -e 's:%::'` / 5 - 2 )) Brightness change 2 to 2 from scale max 20 (100/5), and decrease a real 10% to this way. With value 3, increase a 15%. I don't know how is the default in it, but value 2 . NVClock accept minimum brightness to 15%, in decreasing 10% you can decrease up to 20%, in 15% decreasing you can decrease up to 25%. Anyway for also solve this little feature?
