Laptop brightness not working, LM17 on an HP-15 notebook

Post by olly1123 »

Hi, I've just installed LM17 on an HP-15 notebook. But I have two problems: first, I am unable to adjust screen brightness using the dimmer keys f2 and f3. Also, the f12 WiFi key is not functioning.

Here is the output of inxi -Fzi

I have tried the usual fix for getting the screen brightness to work, namely editing the line in the GRUB file to read something like "quiet splash backlight=vendor" followed be update-grub and reboot. But this had no effect. Editing the line beneath that resulted in my laptop not booting: so I am weary of making any changes here.

As for getting the Wifi button working, I have no idea what to do!

I would really appreciate some help. My laptop screen's so bright its burning my eyeballs in their sockets!
