The package 'samsung-backlight' just enables the brightness to be controllable.
Instead, the problem you are experiencing is probably caused by a KDE bug, other users have the same problem:

I suggest you to file a new bug report on launchpad about the problem.

Hi!
I try to install samsung-tools, on my Samsung R60, and all Fn keys work`s fine. But I had to add model name *R59/R60/R61* to the files: 95-keymap.rules and 95-keyboard-force-release.rules.
Can you add my model name to the samsung-tools?
Thanks in advance!

Hi guys, in first place i would like to thank you for your work, it seems your tools are very useful in improving the experience in Ubuntu with Samsung laptops.
I have a Samsung Q320, it's not exactly a netbook, but it seems to have it same problems (ie: my fn-key don't work, not even after installing samsung-tools).
How can I add support for my model? (320/P320 btw), what do I have to change? thanks in advance!

ignore my first post, I added my notebook model to 95-keymap.rules and 95-keyboard-force-release.rules and now all the fn keys are working fine.
the only problem is that I can't control the bright level normally, I wave to do it via nvclock -S -10 or nvclock -S +10. is there a way to make fn+up and fn+down run those commands?

Hello,

First of all, a big big thanks for your work! It is so helpful!

I have a Samsung R580
with NVIDIA Driver 195.36.24
and xorg.conf with "RegistryDwords" "EnableBrightnessControl=1"

So far with Kubuntu 10.04, I can configure the power management to set the brightness on logon.
And I can also change the brightness by writing directly to /proc/acpi/video/NVID/LCD/brightness

I have the same problem when pressing Fn-up & -down: current brightness level is shown, but it doesn't change. So I tried to install the samsung-backlight package and I observed the same result as someone else: when pressing up & down, the BL flickers and goes respectively to max & min.

So I rmmod-ed the BL module and after that, the behavior was normal! I could go through all steps, one by one. My next try was then to blacklist the module and reboot: but I was back to showing level without being able to change it. And modprobing the module didn't change that frozen behavior.

So it seems that loading the module at boot time does something special that can't be done afterwards. Maybe this can help you change something.

Thanks again
Michel

Dear voRia! Thank you very much again for your perfect job, it makes life w. Samsung easier! :D
Unfortunately, after recent kernel update (04 June 2010), uname is 2.6.31-22-generic, all Fn-keys (all, starting from Br-Up, Br-Down to F7,F8, etc) started "cycling" - one press - repeated behavior. Do you require any info from me - please ask!

NB: Samsung X118 (X120), kernel: 2.6.31-22-generic, Ubuntu 9.10.

A new official kernel for karmic has been released yesterday, newer than the fixed one available on my repository, and with your last system upgrade you have installed it.
Now I've added on the repository the new fixed version, so all you have to do is to perform a system upgrade again and the FN keys should start to work again. ;)

Thanks for the detailed report. ;)
Unfortunately, I think there is nothing I can change in the 'samsung-backlight' module. It works as it should on ubuntu, and I'm pretty sure the problem is in the KDE power manager daemon. As another proof of that, I don't use the 'samsung-backlight' module at all on my NC10, since the backlight control works out-of-the-box here... well, with ubuntu everything's fine, with KDE the FN keys don't work (current level is shown but frozen).

Anyway, if removing the module helps you, you can add a simple script in your '~/.kde4/Autostart/' directory which issues the rmmod command just after your session is started. :)
