Linux On My Samsung

After
sudo apt-add-repository ppa:voria/ppa
sudo apt-get update
sudo apt-get upgrade
sudo apt-get purge samsung-backlight-*
sudo apt-get install samsung-backlight
sudo reboot

Using kernel 2.6.31-20-generic, the FN-UP and FN-DOWN keys adjust the brightness as expected.
Thanks very much ...

Sadly not. After upgrade to 10.04 LTS FN-UP and FN-down still do not affect the Brightness. The command setbright still works ok, though.

Hi, sorry, the Python code is dependent on indentation which is removed by posting the reply.

Try the following but replace all the '>' characters at the start of the line with TAB

master=Tk()
var = IntVar()
def set(v):

from Tkinter import *
import os,sys

master=Tk ...

Oops. indent the last two lines in the "while 1:" loop. Copy and Paste!

Luckily, I installed one of my two NB30's as dual boot and I downloaded and updated the BIOS on it to the latest and the FN-UP and FN-DOWN keys still do not change the screen brightness under Ubuntu. Frustratingly,the buttons do work in XP!

I tried listening to /var/run/acpid.socket with the python ...

hi,

please ignore the 20_samsung_scripts point, I have reinstalled them.

The bios in /var/lib/acpi-support/bios-version is "05JJ.M030,20100218.RHU".

How do I get an update to a later version?

Hi,
Thanks for your suggestions but they did not work for me. I have however fixed the Wireless resume problem.

Wireless on Resume
Yes it appears to lose Wifi on every suspend-resume cycle. I yum removed samsung-scripts but get the same behaviour. I do not even get "Wireless Network\n disconnected ...

Hi, I have recently purchased 2 NB30's and installed Ubuntu 9.10 Netbook Remix on them. I read the posts on this website and installed the repository ppa:voria/ppa and updated the install.

It works very well apart from two problems: the screen brightness control and resumption after sleep
