I am having issues with my brightness working on my laptop (stuck on max brightness); it uses the Intel HD 4000 graphics driver, however I had similar issues with it when I was using Windows 10, I found that using the default Microsoft Basic Display Driver that comes built in fixes this; which is a replacement for when software from hardware manufacture isn't installed.

Samsung ATIV Book 4 - NP470R5E-K01UB

• current OS - Linux Mint 19.2 Xfce


• Intel HD 4000 graphics driver


• LED display

My overall question: Is there a Linux alternative to Microsoft Basic Display Driver? If so, how can I remove my current graphics driver and install that one?

My goal is to get the brightness controls to dim my display with the fn control keys.

Additional Info:

Read here: How to adjust brightness on Samsung ATIV Book 4, other users switched to Windows 10 from Windows 8 experienced same problem.

Currently using Brightness Controller program to dim my display as xbacklight does not work, xrandr does work but unable to figure out how to connect it to my fn keys

ls /sys/class/backlight/ # gives me intel_backlight

Solutions Tried:

Created a 20-intel.conf file in /usr/share/X11/xorg.conf and /etc/X11/xorg.conf with the following;

Section "Device"

        Identifier  "card0"

        Driver      "intel"

        Option      "Backlight"  "intel_backlight"

        BusID       "PCI:0:2:0"

EndSection

Tried the following grub configurations:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=video"

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi="

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi=Linux"

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=intel_backlight"

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=intel_backlight"

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=intel"

#This last option made it dimmer but didn't allow brightness control
