Closing since the brightness control itself works starting with Karmic

link in #23 for alternative solutions if you don't want to upgrade your
BIOS.
However, there are related issues which don't affect the brightness

On My Samsung R580 i have the same issue: if you let the mouse on the
brightness applet, a tooltip saying "Unable to get Screen brightness" appear
(the real message is a french one "Impossible d'obtenir la luminosité de

So is it an ACPI issue ? see hal.txt a resulting lshal output file

I can only speak for the brightness buttons.
It worked like a charm in 9.04 even with the old BIOS.
In 9.10 nothing happened. After upgrading to the latest BIOS the keys
functioned again. But I had some difficulties, when running with the battery.
The brightness decreased itself after a while idl
This issue is definitely a bios/kernel/driver issue. Do we know if this
used to work in previous releases of Ubuntu?

I run the latest BIOS (11CA 15.09.2009) on my NC10. In the BIOS Setup I set the
"Brightness Mode Control" to "User Control".
I use Xubuntu 10.04. Installed the Beta updated every time.
scan code: 0x88 key code: brightnessup
scan code: 0x89 key code: brightnessdown
scan code: 0x86 key code: wlan
Ok, in BIOS Setup I changed the "Brightness Mode Control" to "Auto" but
that doesn't help.

According to bug 337370, there seem to be some issues with older bioses

Now I need the output of lshal. On my macbook, I have a
computer_backlight udi with laptop_panel properties. One of the two gpm
backlight mechanisms uses hal, and it only works if it can find a udi

I tested all the keys, and the ones that don't work are the brightness
and the wifi keys. It seems like the keys are registered correctly. It
looks like there's nothing wrong with the key assignment. Here's what
I've found:
$ /lib/udev/findkeyboards
$ AT keyboard: input/event5
scan code: 0x88
I need someone to help me debug this. Please do the following:
$ /lib/udev/findkeyboards
You'll see something like "USB keyboard: input/event5". We are
interested in the "input/event#" part. Next:
$ sudo /lib/udev/keymap -i /dev/input/event#
Where # is the number determined from findkeyboards.
It is also the case in Xubuntu 10.04 beta. It only shows The Window with
the bar, but no change in brightness occurs. The bar is also uneffected
and remains half filled.
