Some ACPI not working on ASUS T303UA

Question

I'm trying to use Ubuntu 16.04 LTS on an ASUS T303UA laptop.

After I installed it I noticed that some of hotkeys do not work (Fn+F5 and Fn+F6 for brightness control, Fn+F3 and Fn+F4 for keyboard backlight control and etc.) but volume control (Fn+F10, Fn+F11 and Fn+F12) work correctly.

I checked the output of acpi_listen and got the following for working keys and nothing for unworking ones.

button/mute MUTE 00000080 00000000 K
button/volumedown VOLDN 00000080 00000000 K
button/volumeup VOLUP 00000080 00000000 K

Also I noticed that the asus-laptop kernel module is not loaded after I tried lsmod | grep asus and got the following result.

asus_nb_wmi 24576 0
asus_wmi 28672 1 asus_nb_wmi
sparse_keymap 16384 1 asus_wmi
wmi 20480 1 asus_wmi
video 40960 2 i915_bpo,asus_wmi

Then I did sudo modprobe asus-laptop and got the error:

modprobe: ERROR: could not insert 'asus_laptop': No such device

I tried the answers for the following questions but it didn't solve.

What should I do next? Any help would be appreciated.

EDIT

My current GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub is:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="

I created /usr/share/X11/xorg.conf.d/20-intel.conf as follows:

Section "Device"
    Identifier      "card0"
    Driver          "intel"
    Option          "Backlight" "intel_backlight"
    BusID           "PCI:0:2:0"
EndSection
