[Bug 76274] Re: Brightness Settings Don't Work

[Paul Sladen]

This is more likely a 'hal' or kernel issue:

  /usr/share/hal/scripts/hal-system-lcd-set-brightness

Currently has the following code for Sonys:

  elif [ "$HAL_PROP_LAPTOP_PANEL_ACCESS_METHOD" = "sony" ]; then
        # echo "{1..8}" > /proc/acpi/sony/brightness
        # http://popies.net/sonypi/2.6-sony_acpi4.patch
        echo "$((value + 1))" > $HAL_PROP_LINUX_ACPI_PATH

Does this work on your laptop.  Could you also please include the DMI
decode data for your laptop as detailed on the HotkeyResearch page above
so that we can identify your laptop.
