Ubuntu 14.04 64bit backlight problems on Samsung P210

Post by andera »


I have installed the 64bit version of Ubuntu 14.04 on my Samsung NP-P210 AAY1DE,
the function keys for brightness do work, but they have no effect on the brightness,
I can manually change the brightness by using the setpci command,
and I have added the file "/usr/share/X11/xorg.conf.d/20-intel.conf" with the content:

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

This seems to help, now at least the function keys do change the brightness,
however, from time to time the screen is flickering and brightness is changing by itself and I wonder if I can improve this by using the packages from this site,

are the Samsung packages here compatible to Ubuntu 14.04 64-bit ?

are there other improvements apart from the brightness control ? (like power battery management etc. ?)
