Po wielu próbach udało się i zostawię to tutaj dla potomności.
Na początku tworzymy nowy plik tekstowy o nazwie 20-intel.conf w /usr/share/X11/xorg.conf.d/.
Wrzucamy do niego to

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


Potem edytujemy już standardowo plik grub który znajduje się w /etc/default/


GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor"


Potem już tylko aktualizacja samego grub-a

sudo update-grub

Restart i to wszystko. Zmiana jasności ekranu w Samsungu NC110 powinna działać.
Myślę że w innych samsungach z grafiką od Intela też to zadziała.

W jednym z linków jest opisany dokładnie ten model netbooka czy mógłby ktoś pomóc w implementacji tego

SAMSUNG NC110

Suspend to RAM: OK
Disk: Not tested
Dimming of display: Yes (with acpi_backlight=vendor)
CPU frequency scaling: Yes

Gdzie dać tego acpi_backlight=vendor?

[PeKaP]

Dupa zbita. Zainstalowałem windowsa 7 i bez dodatkowych sterowników zmiana jasności działa bez problemu. Kolego możesz podać dokładne możliwości zmiany parametru acpi_osi?

[PeKaP]

Procesor to Intel Atom N455 1667 mhz. Wspomnę jeszcze że w trybie live zmiana jasności wyświetlacza działa bez zarzutu tak samo w grubie ale w połowie ładowania systemu wskakuje na maksymalną jasność i tak już pozostaje.

Niestety nie, skróty klawiszowe działały przed instalacją tak samo jak po a jasność nadal nie ulega zmianie.

Instalacja zakończyła się pomyślnie. Bardzo dziękuje za pomoc.

If I enable samsung-tools.service to start on boot, I am unable to control the webcam until the system service is stopped. In the gui, all webcam-related settings are greyed out and samsung-tools -s webcam returns "Webcam control is not available." If I then run samsung-tools -S followed by another samsung-tools -s webcam, it returns the actual status of the webcam.

If I disable start on boot this problem does not appear, but the devices are not set to their initial state until I run the service manually so I disabled start on boot and run the service from .bashrc as a workaround.

Note that the webcam itself works as expected as long as the uvcvideo module is loaded.
If you need more info please let me know.

Disregard my previous comment, solved by uninstalling laptop-mode-tools...

As @smrtg suggested it in samsung-tools-git, pm-utils has to be removed from the dependencies here and from the developpement as well: it seems to conflict with systemd's LidSwitch.

With Samsung Tools installed, resuming from a LidSwitch suspend leads back to suspend a few seconds later.
Without Samsung Tools installed, so without pm-utils installed, suspend is working as expected.

AFAIK it would lead to some code refactoring, as VM writeback, Devices Power Management and USB autosuspend are pm-hooks. They can be handled by UDEV rules, as described in Arch wiki's Power Save page. We can even make them depending on power supply events.

Enabling wireless with the Fn combination leads to some weird "Wireless cannot be enabled", despite it's enabled after a while.
Blacklisting the samsung_laptop module gives the right message, but the battery life seems to be impacted.

systemd-backlight doesn't restore the backlight level (Linux 3.16.1, GNOME 3.12.2, systemd 215-4), I have to force X11 to use intel_backlight instead of samsung's to make it work.
intel_backlight is less smooth than samsung's used to be, the minimal level is a black screen, but samsung's isn't adjusting backlight at all now.
Adding acpi_backlight=vendor and other stuff to GRUB makes no change on my N210.

Since kernel version 3.16, I've been having problems with the backlight on my ATIV Book 8. 

First, the function keys to control the brightness stopped working. I've fixed that by adding acpi_backlight=vendor to the kernel parameters.

Second, after a resume the backlight does not come on at all. The screen is not black, but so dark it is almost impossible to read. This problem is very intermittent and I can't reproduce it consistently. I've played with video.use_native_backlight but haven't found a solution.

Dziękuje za odpowiedź i faktycznie znalazłem kilka wątków dotyczących tych toolsów. Pakiety zapisane są w formacie tar.gz wyjdę na noobka ale za cholerę nie potrafię tego zainstalować.
