HP Omen keyboard control on Linux

[taylorcoons]

I've thought the HP Omen control was limited in my personal opinion so I looked into writing the software to control the LED's. However, I was quite unsuccessful and HP keeps this quite proprietary. I have found out several things though that might be of use (hopefully). 

First the settings for HP Omen control are stored in the registry under the key:

HKEY_CURRENT_USER/Software/Hewlett-Packard/HP OMEN Control/

When settings change in the HP OMEN Control GUI the updated settings are written to the Registry. However, when the HP OMEN Control GUI opens the settings are not loaded from the Registry but instead some save file that I have not been able to locate. 

When the HP OMEN Control settings are changed in the GUI several things happen:

1. The settings are written to the Registry (as mentioned)

2. API calls are made to update the GUI.

3. A helper executible is ran that causes the actual changes to physically take place

This helper executible is located next to the HP OMEN Control software install location. The helper executible is named HPOMENCMD. When HPOMENCMD is ran:

1. The current settings are loaded from the Registry Keys

2. Several Win32API/System calls are performed to actually impliment the physical effects.

I attempted to figure out the exact calls that causes the update but decompiling the helper executible was out of my time/expertise range. 

In conclusion though it is possible to make your own gui (in windows) that sets the registry keys to allow and then update them by making a subsequent call to the HPOMENCMD executible. If the exact process(es) that causes the physical changes to take place can be tracked down then it might be possible to write your own software program for linux.

Best of luck!

Have you tried the GHIDRA ? It should be possible to get the source codes from any exe (so I guess even from the HP control app) and use that to learn how they control the LEDS... it would be usefull to make some linux app for that because I also have linux on my Omen (I have to because of my job) and its so **bleep** frustrating taht HP will not give any support for such a big money that Omen costs..... Shame on you HP.....
