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"

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

  • Try the video.use_native_backlight=1 kernel option, too.

Okay, after multiple attempts on my machine, given our systems are similar, here is what I did and it worked.

have a file in/usr/share/X11/xorg.conf titled 20-intel.conf

Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "acpi_video0"
        BusID       "PCI:0:2:0"

note how it directs to acpi_video0 instead of intel_backlight

next was to tackle /etc/default/grub set GRUB_CMDLINE_LINUX_DEFAULT to

GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux acpi_backlight=acpi_video0"

now I'm not entirely if this will help but, this is something I did earlier and I'm not sure if it affects what is above.

I also followed the ArchWiki about setting an udev rule for users in the video group


ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="acpi_video0", RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness"
ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="acpi_video0", RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"

so add yourself to the video group and update grub too and hopefully upon reboot it works.

(sorry about formatting and stuff, I am new to linux and to forums it seems)
