It doesn't matter if I enter the lowest possible VID - the stability and battery life seem to be unaffected.
I honestly don't know if Atom N450 is supported.
Since 'Samsung Tools' is just a GUI to the PHC interface, it works only with CPUs supported by PHC.
You should ask directly to the PHC developers for more info: http://linux-phc.org/

Well, it seems 'rfkill' recognizes your bluetooth device... everything should work good.
Try to reboot, if you didn't do it yet since last system upgrade.

I am using samsung N148 and for me samsung tools is working but on the kernel installed during installation of samsung scripts in karmic.
I have writing this because i read that in some models samsung tools works out of the box without the need to recompile the kernel, well that not what happened in my case. The Shipped kernel is not accepting to toggle anything but the webcam.
If you have done the dist-upgrade from karmic to lucid, and you installed the package 'easy-slow-down-manager' in karmic, you need to force its reinstallation in lucid:
Probably this command will also uninstall 'samsung-tools'. Reinstall it, then use this command to force the Samsung Tools' system service to stop (and restart):
When i did this in the new kernel samsung tools worked in the new kernel but stopped working on the previous kernel. Is it a bug or is it intended that way?
It's not a bug, the fact is that now the 'easy-slow-down-manager' module is automatically rebuilt when a new kernel is installed. The old karmic version instead needed to be updated for the latest kernel everytime. Things work differently now, and if I can give you a suggestion, remove the old karmic kernel since it's unlikely to be needed anymore in lucid.

I was playing with 'advanced power management' and I'm uncertain which settings are correct for me. Since I've installed laptop-mode-tools lucid is booting and shutting down slower than before, so I only ticked usb-autosuspend, ethernet, audio and video-output to reduce the effects on performance to a minimum. I do not understand what the other options do or in what way they influence the performance on the system and I do not know which value to set in the power-management window. Are there any suggestions Thank you in advance
I think the only options affecting performance in a noticeable way are the ones related to Hard Disk management. Mainly the last one, "Hard Disk power management". By default laptop-mode set it to 1, which means the HD is put to sleep very often, as soon as it's possible. This saves a lot of energy, but everytime the HD is accessed it has to be restarted and this requires time. Also, this is not good for the life of the mechanical parts of the HD.
Personally, I set this option to 192, in order to favor performance over power saving.

Hi, new owner of N150 here. I'm using UNR Karmic, and your Samsung Tools works very well as I was very keen on adjusting the brightness of the screen. Only remaining problems are, apology if posted on the wrong thread, a) bluetooth is not enabled but wireless is, and b) wireless signal is quite weak. next to me is my other Dell laptop and the wireless signal is full as the router is less than 5 metres away. On this N150, the signal has been fluctuating, reaching about 70% highest and disconnects itself at times.
Please if anyone has any solution please let me know. Cheers,
