Asus Zenbook UX303LN not all function keys work.

Fn + F5 or F6 adjust backlight in windows. Non responsive in Apricity OS. Backlight is adjustable trough terminal commands or with brightness slider in gnome.

Fn + F9 Should toggle the touchpad ON/OFF. OSD graphic indicating buttonpress is shown but touchpad state is not toggled.

All of @okristian1 said happens to me and more, the zenbook home,end,pgdn and pdup keys whose are located on arrow keys and activated by Fn don't work too.
I've no tested yet, but follow the instructions here might put the backlight to work

My keybord is configured as International + deadkeys

I was just about to link the archwiki page for you when I noticed you put it in your post. The instructions on Function Keys will probably fix your issue.

Yep, fix lots but not all. I'll still try to fix the remaining ones. I figure out the arrow keys + Fn just don't work on terminal, on chrome or nautilus they're working fine.
The airplane mode is working to turn ON, but failing to turn OFF, a great thing is the menu shows the airplane mode enabled allowing to turn it OFF (again thx ApricityOS, I'm glad to find you)

Now, I still confirm the @okristian1 claims about touchpad (un)lock and backlight.
