It's a fault in how some of the Fn keys don't send the key release code,
making the OS think that the key is being held down. I have submitted a
patch to the kernel which fixes this issue, allowing the Fn keys
(including brightness) to be used properly.
For those who want to see the patch:
As it seems that at least part of the problem is due to the keys not
producing keycodes, I'm assigning a hal-info task, where a quirk can be
added to provide the correct scancode - keycode mapping.
** Changed in: hal-info (Ubuntu)
Sourcepackagename: gnome-power-manager = hal-info
Importance:
just to inform that i opened 2 bug report
one on kernel.org
and an other on Xorg
here is the link of the last one
http://bugs.freedesktop.org/show_bug.cgi?id=18590
because with acpi=off it worked, i opened first an acpi bug, but in
console mode (CTRL ALT F1 for example) the brightness work
On my NC10 the Brightness Keys are working, however, if i used them
once, the keyboard is completely dead and XFCE hangs (Menus are not
opening any more).

encountered these problems on boot:
Frequency CPU scaling doesn't work anymore.

Samsung NC10 brightness keys block keyboard
I installed Hardy (8.04.1) using the Alternate installer and I had to
use acpci=off as a boot option to install Ubuntu. I noticed that when I
used this boot option the brightness keys such as the up and down arrow,
but also the FN+F5 key worked as expected. Perhaps this info can help us
further
I made a typo in the description before.
Its not:
acpci=off
but
acpi=off
Sorry.

Doesnt look like somebody is interested in solving this ...
Thanks for nothing, other distris are much quicker than you.
I found a solution, so no need for you to look at this ... the few 10
owners will be happy with Win XP.
Good work.
I wish you good luck, you will need it.

maybe this can help you guys, at least i hope so :
i killed gnome-power-manager and run it this way
gnome-power-manager --no-daemon --verbose
i pressed the decrease button ONCE and then the increase button ONCE (because
the brightness was at 0%)
then i switch to console and back in graphic mode
I have the same problems with the fn-keys, which were written above... I
hope that these problems will be solved.. thx

I have the same problem.
But maybe this helps:
I also set the keymaps Andreas already described. After an X restart i´m able
to use the brightness keys and the keyboard gets stuck.
But i can still switch to a console with the ALT+CTRL+F1-F6 keys. After
switching back to X with CTRL+ALT+F7 i am
