Samsung NB30 Netbook - Brightness problem

[voria]

You're welcome!

This worked for me for a while.. I did a full update/upgrade last night.. FAIL.. back to where I started. The brightness bar moves but no effect.

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!

Unfortunately, I also have an option, the default, for kernel 2.6.32-21-generic and using this, the brightness keys do not work and also wireless is inoperable. Is this a known problem?

Unfortunately after a System Update on my Samsung NB-30 (touchscreen) everything went back to the original mess:

- backlight management is not working anymore
- wireless is not working anymore
- FN keys not working anymore
- touchscreen working though

The original fixing methods, such as installing Samsung-tools from the Voria PPA repository seem not to be working anymore.

Very frustrating indeed.

Anyone?
Thanx

Thank you VoRia for your work. There is usually no reliable HowTo matching certain equipment, but you did a good instruction. Keep updating!

However, the backlight scroll does not work for my Samsung NB30. Actually keys are working but nothing happens. Hope this problem shall be solved soon.

I know this thread is over a year old but was wondering if there were any new developments.

I have the power-up problem on my NB30, the brightness is low if I power-up on battery, it is fine on AC.

The Fn keys do not appear to respond, so no adjustments available there.

I am using Puppy Linux dpup Exprimo v5x15

Kernel 2.6.39

Thanks!
