Brightness fix for Lucid from Joe L

with 10 comments

As I have not moved to Lucid yet, not much played with brightness.

Then thanks to Joe L, I guess he found a universal brightness fix for Ati and radeon/hd drivers in Lucid. Read it, try it and report back how it works 🙂

  1. Hi egaistek,

    Note that this is not a universal solution. In the previous thread it is being reported not working for at least these models:

    . FW31ZJ
    . FW35G_B

    I’d like also to note that according to the docs HAL has been removed from 10.04. This may actually be the problem:


    Thanks to Sean for the link.

    • Just as an addendum, the fix provided by Vânio Ferreira works perfectly well for the FW31ZJ (which I own). Though it seems it has to be repeated every time there’s some system update.

    • This solution is also failing with models FW21 and FW41. But on both of them installing the latest ATI driver is being reported as a solution.

  2. The brightness issue it’s a story in Vaio-Ubuntu, just after install it, insure that you charged the correct driver for nVidia, for your kernel, and go to check in your Synaptic that you have installed the “smartdimmer”, then open a terminal and type:
    smartdimmer -s 50
    You’ll set you brightness to 50%, if you want it less do it…
    And to set this issue to start with you system in start up, go to system – preferences -startup applications, and set it as application to start with…
    It’s less then 1,2,3….
    Viva Ubuntu!!

  3. I can also report that this ‘universal’ fix does not work for my FW-390.

  4. Didn’t work on my FW390J (sticker says VGN-FW390, but oddly the command returns FW390J). 😦 Appreciate the work though!

  5. Quick question: are you using the open source driver or the ATI one?

  6. YES!! Finally!
    Installing the Catalyst 10.7 / fglrx 8.753 solved the problem right out of the box.
    This whole problem made me so angry!

    By the way:
