Title:
Cannot change screen
Is anyone looking at this? I've tried the two hacks posted and neither
of them work for me on the HP Pavilion.
It's troubling if this hasn't been addressed after a year. Screen
brightness is a health and safety concern. It may seem like a small
issue, but being able to see the screen comfortably
I have done some more testing following the guidelines on
https://wiki.ubuntu.com/Hotkeys/Troubleshooting .
If I execute killall gnome-settings-daemon gnome-power-manager the
brightness hotkeys starts working perfectly except there is no on screen
display.

Cannot change screen brightness on
Found some help on
https://wiki.edubuntu.org/LaptopTestingTeam/HPCompaq6930p/Intel .
Executing xrandr --output LVDS --set BACKLIGHT_CONTROL native make the
brightness fn key work on Acer 5315 laptop.

Cannot change screen brightness on Fujitsu T2010 laptop in Intrepid
Just wanted to add that the same brightness issues can be found on a
Acer 5315 laptop running Jaunty beta.
Adjusting volume work fine using the fn keys, but brightness does not.
The brightness OSD appears but I cannot change the brightness.
Changing the brightness using the gnome brightness
This appears to still be the case on portables, specifically for me, on
a Lenovo SL500. Using the Function key to increase brightness by
pressing the brightness UP key combo, will raise the display
brightness by one notch; subsequent key presses will then decrease the
brughtness a single notch,
I'm sorry I forgot to add that I'm trying it on the latest Jaunty alpha
6 (kernel 2.6.28-11).

Ok, the fix probably doesn't apply to me. In terms of behaviour, it does
appear to be exactly the same bug, though - I press the buttons and the
little brightness symbol appears, and looks like it is being increased
or decreased, but the screen brightness stays exactly the same. I unplug
the power

Hi Duyn,
Thanks for the info you've posted. I just tried upgrading the kernel as
suggested but it didn't like the NVidia drivers (and in basic graphics
mode it wouldn't let me change the brightness, which doesn't auger
well).
I've tried using the xrandr command but this is what happens:
Sorry, the fix doesn't apply to you. The Fujitsu T2010 has an on-board
intel graphics card. If yours has an NVIDIA card, that's a different
bug.

I also have a Fujitsu T2010 and have experienced problems changing LCD
brightness in Intrepid (8.10). Changing brightness with the Fn+... keys
never worked in Ubuntu, though using xbacklight used to work (I don't
remember exactly when it stopped working).
I found 2 possible solutions to this

This and subsequent postings contain kern.log, hal.log, lshal.txt as
requested. The buggy actions are using Fn+F6 (lower brightness), Fn+F7
(increase brightness), unplug AC (reduce brightness to 50%), and plug AC
in (increase brightness to 100%).
Same problem here: Fn keys adjust the brightness

updating to the 2.6.28-5 kernel made the brightness control with gnome-

adjusting the volume, muting, suspend the wireless killswitch, webcam

Cannot change screen
Changing screen brightness does not work on my Fujitsu Siemens Amilo SI3655.
In Intrepid gnome-brightness-applet worked, it doesn't work with jaunty alpha 3

As of 2.6.28-4-generic on Jan 7, 2008 on daily-live USB via unetbootin
the screen brightness *works* !!
Caveats:
It's touchy. It can be slowing. Sometimes a little touch on the key can feel
like 3 or 4 presses.
Other times the brightness indicator in GNOME doesn't come up.

Is this symptom still reproducible in a daily-live of jaunty?

I'll try to help however I can. This is my first time doing a HAL debug!
:)
Test info:
- I restarted the t2010.
- Gnome opened, logged in
- I did the HAL recording.
- I did do some copy misc copy commands, a few lines did scroll while I did it.
- I proceeded to fn+F6 (dim) twice and fn+f7

Thank you for taking the time to report this bug and helping to make
Ubuntu better. Unfortunately we can't fix it, because your description

re: My above comment, in which I said:
Unplugging the AC adapter while in Gnome dimmed the screen a little.
Plugging it back in restored the original brightness.
This no longer works for me in up-to-date Intrepid. (For all I remember, this
actually may have only worked when using the Alpha 6
I own a Fujitsu Lifebook S7210.
Basically, the situation is the same as described by Bruce Wolfe. The
Fn+F6/F7 keys were not working at all on Hardy. I wasn't able to change
screen brightness in any way. xbacklight could dim the screen, but I
think it wasn't using ACPI and I didn't have the
I also own a T2010 - I am using Intrepid Beta. Observations...
* Fn (F6F7) keys bring up onscreen applet and change the values but the
brightness doesn't change.
* related - the values change two steps at a time - both up and down.
* xbacklight can be called directly using get set, but again no
