Backlight Controller with LightFX

-What it is:
1 colors settings

This is a custom backlight controller intended for Clevo models with
backlit keyboards. It is a replacement for the standard Clevo keyboard
app.  By default it works like the original. If you want to take
advantage of some of the advanced effects you’ll have to set the app to
start with windows (there are all sorts of option in the settings page,
top right)

-Project status:

A first public beta is available for download


Haswell CPU’s temperature reporting. I don’t own a Haswell so if any of you does let me know if it works or not


-Hotkey driver MUST be installed and working.

-.NET 4.5 is required. Windows 8 have it by default. Other systems need to install it by hand.


Run the setup and follow the instructions

-New effects

So far we have 3 new effects:

1) Temperature/Usage lighting. Some of you will probably
already know that one. It’s using pizzadude223’s code. Lights change
depending on temperature of CPU/GPU. Dual GPU’s supported

2) Audio lighting. Lights change depending on intensity of the
music. Keep in mind that lowering the latency will increase CPU usage
so try to find the sweet spot on your system

3) Heartbeat. Lights follow a heartbeat pattern that increases in speed according to CPU usage

4)Adaptive color effect

This effect works for applications that run in non-exclusive mode. That means windows apps and games running in either windowed or borderless modes only (ie no fullscreen).

This mode lets you color  the keyboard based on what happens on the screen.

You have 2 basic modes, “Aero” which basically colors the keyboard according to the aero color in windows and “Screen Average” which scans the screen to determine what the average color is.

When you use Screen Average you have certain extra ways to tweak your color. You can choose whether to use a single color for the whole keyboard or use a different one for each keyboard region. When you use 3 colors, each color is decided based on what happens on the screen part that’s over that region.

You can further tweak coloring by specifying what part of the screen will take place in the decision. You can have the whole screen or just the lower or upper half. That’s useful if for example you’re playing a game that most action takes place in only half the screen. For example in a racing game the upper half of the screen is usually just sky.

There is an option that will affect the sensitivity to color changes, that’s what the minimum diversion does. Lower will be more sensitive.

You can also choose whether you want brightness to vary with colors or not. The minimum brightness makes sure that the brightness will not fall under any circumstances bellow that limit.

The update rate is like in other effects the speed by which the effect refreshes. A word of notice on this one, this effect is a very complex operation; it’s not a simple thing. If you overdo it you will get a SEVERE performance hit. I find that 50ms is a good compromise between speed and performance.

Keep in mind that this is still a BETA.

It means that bugs are normal to be found. We will try to address them in turn but you’ll have to be patient.

I’d welcome any comments or bugs you may have to report but in order to
make it easier I want you to always post your specs along with a
detailed explanation of what you are reporting.

Also make sure that the problem is repeatable.


This is freeware. You may use it freely. I would appreciate distributors interested contacting one of us first


Apart from the default themes (That you can switch via the settings menu) you can create your own too. The app’s theme engine is modular. It means that you can theme only the items you want, without the need to change everything.  It is very flexible but it has it’s limits so be careful if you’re a newbie. If your theme crashes the app, just delete it and the functionality will be restored.

The themes are each stored in a unique folder located in  Hotkey’s installed location (c:\Program Files (x86)\Hotkey\themes).

The theme’s name is its folder name.

You will see that there is a “template” theme. It’s a guide to help you on your first steps. Be sure to read both the readme.txt as well as the theme.txt placed in there. They describe most of the stuff you’ll need…
