Keyboard backlight

Not working:

• Fn + Up/Down shortcut

Working:

• nothing...

brightness and color must be set on Windows once with the AURA Lighting Control application

Kernel option

For fixing keyboard backlight or lcd are not working none of this options fix the problems:

acpi_backlight=video
acpi_backlight=vendor
acpi_backlight=native

I have Asus GL503VS. I had similar problems with function keys. Here is what i've done.

• installed ubuntu 18.04.1

• downloaded kernel source from kernel.org, I decided to downlad latest stable (at time of writing https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.19.7.tar.gz)

• unpack that tar xvzf linux-4.19.7.tar.gz

• open cd drivers/hid

• edit vim hid-ids.h

• line #define USB_DEVICE_ID_ASUSTEK_ROG_KEYBOARD1 to #define USB_DEVICE_ID_ASUSTEK_ROG_KEYBOARD1 0x1866 where 0x1866 is the id of my keyboard, so maybe it is similar with these models

• compile kernel (there is somewhere good tutorial how to do that)

• install kernel with modules

• reboot to new kernel

• try function keys - they should be working

• now to make screen brightness work you need install nvidia-driver-415 (or maybe any driver higher then 396)

• it will work out of the box but if not add this line to grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia.NVreg_EnableBacklightHandler=1"

• now screen brightness should work

• keyboard backlight can't be controlled, really can't figure this out because I don't know how it is initialized in windows

Hope this helps. Touchpad was working out of the box so don't really know how to help there.

In gnome i get random freeze, am trying to figure that out too.
