xfce4-brightness-plugin : no device found

When I mouseover the brightness plugin, it says no device found, and I am unable to adjust the backlight.

I know other distributions allowed me to.

When I try xbacklight, I get 'No outputs have backlight property.'

I have no idea on how to go about fixing this.
Do you?

AFAIK, KMS will handle the backlight properly. Is it enabled?

KMS is explained here http://wiki.archlinux.org/index.php/KMS intel specific here http://wiki.archlinux.org/index.php/Intel In short, AFAIK, graphic card/adapter initialization and configuration are done in kernel, without the need for user interaction. That way, user should get all graphic related stuff setup as soon as kernel loaded (this includes native display resolution both in console and X, backlight control, power-saving, etc). Follow the instruction mentioned in wiki above, and let's see the result.

I followed the wiki and yes, I can move the slider bar and use the FN keys now, but the backlight doesn't change.

On other distros I had to use acpi_backlight=vendor, to get it working.

But if I do that, then it will say no device found again.

Eek.

I'm in the same boat as you Rouzes. After searching the forums and the internet for a fix, I just gave up and dealt with it

I had the same problem, downgraded the intel video driver and everything works again.
