Confirmed on my Thinkpad T42 and T40
Echoing 'up' 'down' or level commands into /proc/acpi/ibm/brightness
results in it immediately being reset to level 0
Not sure if this is gnome-power-manager that has the problem or
something lower-level. Testing it without gnome-power-manager running
sees
Miguel Gasper is right. I have an ASUS M6Ne. I think that there is a
misfuncion in gnome-power-manager guis (changing the values from gconf
editor works). the applet did work in the past!
I get these errors:
[gpm_hal_device_get_bool] gpm-hal.c:204 (12:22:52): ERROR: No property
Happening on a regular T43 too (all Thinkpads?).
A workaround for me was to do killall gnome-power-manager, then I can
use the brightness keys fine.

This also happens in a Asus L3C laptop (Feisty, upgraded 5-02-2007). Altough if
I change brightness via g-p-m-brightness-applet it will show the correct value
in the tooltip, until I pop the scroll, which will always show at 0% and reset
the tooltip to 0%. It still flickers badly when adjusting
Bug #81920 claims that the problem is because Brightness is 0 due to
setting a non-schema value

Even when forcing `laptop_panel.brightness_in_hardware' to `true' and
running ``sudo /etc/dbus-1/event.d/20hal restart'' then nothing changes
for me.

Confirm on a Thinkpad T43p.
Booting with the noacpi option still has this problem.
A workaround (to avoid going insane...) is to open the Power Mgmt
preferences from gnome-control-center, and under your current setup (ie
AC power), slide the brightness slider all the way up to 100%, then
lower
could you please check if 2.17.90-0ubuntu3 of gnome-power-manager fixes
it

Please _don't_ try booting with 'noacpi' in this case. It will have the
affect of /disabling/ all the power-management and related code!
The solution is to not have g-p-m take any notice of Brightness Key
events on ThinkPads *or* to not fake those Key events in the first
place.
Doing:
sudo
The key events need to be generated in order to trigger the brightness
information.
/usr/share/hal/fdi/policy/10osvendor/10-laptop-panel-mgmt-policy.fdi
needs fixing to recognise all Thinkpads, rather than the somewhat
bizarre subset that it currently does. This isn't a g-p-m issue, unless
Confirmed here on my T42,up-to-date Herd 2.
Flickering when I move the slider up and down,my brightness applet says
LCD brightness : 0% ,however the brightness is set to the highest level.
[EMAIL PROTECTED]:~$ cat /proc/acpi/ibm/brightness
level: 7
commands: up, down
commands:
This is down to interaction with 'thinkpad-keys' in 'hotkey-setup'.
Changing the slider updates the NVRAM values for the brightness.
'thinkpad-keys' notices the changes and thinks it's a key-press (Fn-Home
/Fn-End), and generates 'Brightness Up' or 'Brightness Down' commands.
Exactly the same here (Feisty on Thinkpad T41p). With the brightness
applet, moving the slider up and down results in flickering, on it's way
there are several positions where the brightness changes non-continous
(jumps down to the lowest or up to the brightest level), as if several
forces are
