Acer Laptop Bightness and Volume Hotkeys not working!

[CeDeROM]

Hey :-) For my Dell laptop the backlight is controlled by hardware, unlike
sound keys where you can assign them to use xf86audiovolumeup/down (or
similar) to interact with mixer. I would search for automatic backlight
hothey that would block manual control, or BIOS settings (like automatic
backlight) or maybe new BIOS would fix that problem..?
Best regards,
Tomek
