    Brightness slider problem - ATI X1400 (Toshiba m100-179)

    Hi,
    I have a Toshiba M100-179 (with ATI X1400 graphics card) and everything works ok with Kubuntu 11.10 but i have one problem:
    - Saving energy does not regulate the LCD brightness.

    I can't change brightness with the slider in the settings to save energy.
    Changing the brightness works only with the key Fn + F6 / Fn + F7.

    When I click the battery icon, the brightness slider is always on the left.
    When I move it to the middle and then plug or unplug the AC adapter, the slider returns to the left (darkest) but the brightness does not change.

    Sorry for my english and please help me.
