I am also a Samsung Q45 user trying to install Samsung-Backlight without success.

I am having the same difficulty - being told that it cannot be installed.

I believe (for me at least) it is because the main packages for samsung-wireless and samsung-backlights are for all architectures, but they depend on secondary packages - which are in the repository, but only available for i386 and lpia architectures. There is no 64bit support it seems.

Any hope of 64bit support? Might it work if we force the architecture (probably not I assume given its kernel actions)?

New 'samsung-backlight' package on the repository. Changelog:

You're amazing, many thanks!

Cool, thanks man! That was quick!!

I've enabled the amd64 architecture on 'mesa', 'udev', and 'samsung-wireless' packages too.

New kernel and udev packages on the repository. Changelogs:

Hi,

first of all, thanks for your great work.
I'm using lucid lynx on a Q45 with 09ST bios, but i'm having some issues IRQ related that were not there with 13ST, so i'm willing to re-upgrade the bios. do you have any plan to support lucid lynx? or, better yet, do you have any instructions on how to build the relevant packages (mainly those regarding brightness and wireless fn keys) on lucid?

thanks!

Yes, I will support lucid for sure, but at the moment I have not tried it yet, it's under an heavy development and things change/break too fast yet.
When will be the moment, I'll start to work on it.

Anyway, you can rebuild the packages for lucid easily (assuming that something new in the new kernel has not broken the compatibility, in which case more work would be required):
- Get the sources for karmic from the repository and extract them.
- Open the 'debian/changelog' file and add a new entry on the top, for the kernel version you are going to build for. For instance, if you are going to rebuild 'samsung-blacklight', add a new entry like this:

- Use the command 'fakeroot debian/rules clean' from inside the sources' directory, to clean and update them.
- Use the command 'dpkg-buildpackage' to build the new package.
If the process stops and complains about missing required packages, install them and retry.
If everything goes well, you'll have the .deb files ready to be installed.

Hi,

At first, thanks a lot for the work you're doing!

Got my new N220 today, removed crappy win 7 starter and installed clean karmic desktop.
I did exactly what you wrote in your first post, but now I have a strange, somehow odd problem ;-)

When I enter the commands provided by samsung-scripts manually in the console, everything works as expected, but as soon as I hit Fn + key it seems like it runs the script dozens of time, cpu load goes up to 100%. Checked the running processes an discovered dozens "sh" with status "zombie". This also occur when i try to change brightness with Fn + UP/DOWN, resulting in a funny flickering of the bar showing the actual brightness :-)

I hope I did not miss another thread discussing this ;-)

greetings,

Hi and welcome to the forum.

You are experiencing a common problem when using the default kernel shipped with ubuntu karmic, with which FN keys get stuck when used, like if you were keeping them pressed permanently.
The problem is fixed in the custom kernel available on my repository, so all you have to do is to update your system:

In any other problem/question, don't hesitate to ask.

Wow, thanks, did that before, at least i think so, but he did something and after reboot it worked.

Thanks Again

Still no lucid package for the backlight support? I am waiting for this to upgrade. Is the kernel not yet frozen perhaps?

No, it's just me, I have yet to find the time to install lucid.

I'll be patient then

First package for Ubuntu Lucid is on the repository now, 'easy-slow-down-manager'.
It contains both the 'easy-slow-down-manager' kernel module (needed by 'Samsung Tools' when it will be released) and 'samsung-backlight' module.
