xonatius / samsung-backlight Goto Github PK

Здравствуйте, Даниил.

Ох уж эти Самсунги! Замучался :( Ваш модуль тоже, к сожалению, почти не работает.
Полное описание проблемы тут - http://brokenbrake.biz/2011/04/20/3aTpax
Кратко: попытка убавить/прибавить яркость через xbacklight вводит систему в помешательство: яркость начинает быстро меняться от минимальной до максимальной раз двадцать. А через Fn+Up/Fn+Down вообще никакой реакции.

Я сдаюсь, у меня не хватает знаний, чтобы понять, в чём дело.
Убил три дня на попытки решить проблему.

Hello!

When I enable "Dim display when idle" in gnone-power-preferences the backligt starts to erraticly change itself after a while. I have to switch to a vt and back to make it stop. I'm using ubuntu 11.04 32bit (kernel 2.6.38) but it also happened with 10.10 (kernel 2.6.35) and the 64 bit edition.

I installed this module to gain support for changing backlight brightness on my new Samsung NF310. Diff showing the changes I made to gain support for NF310 is at the bottom.
