Depends on the laptop. Some can dim using acpi, many have a video card specific tool like radion-tool that can set the backlight. Asus has ACPI modules that control screen brightness and the like for their hardware. If your acpi-support scripts are good enough the laptop brightness keys can also work whatever they are. Putting a light towell over the screen also works if you can get none of the above to go. Regards, Kerry. On 8/11/2011 8:45 AM, Littlefield, Tyler wrote: > Hello all: > I have a question.
