User-Agent: Mutt/1.5.17 (2007-11-01) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi! Some time ago, FN-Home/End just adjusted the brightness, and /proc/acpi/ibm contained backlight control. In 2.6.27-rc5, /proc/acpi/ibm does not contain backlight control and /sys/class/backlight is empty... (I do have CONFIG_ACPI_VIDEO disabled, it killed my machine last time I enabled it, is it mandatory now?)
