How do I enable the keyboard backlight on aspire lite AL 15 41

Vijayvithal · March 15

I purchased an aspire laptop yesterday and installed linux mint on it. The main reason for selecting this laptop was its backlit keyboard.

The backlight works when I am booting or using windows, but is always off under linux.

brightnessctrl does not list keyboard as a device

brightnessctl -l                                                                                                                                                                                                                       ─╯
