Hi All,

First post here - really pleased to have found this resource.

I've got a new Samsung N220, installed UNR 9.10 on it - everything I've tested is working now apart from the backlight.

More specifically, the key combination of Fn + UP or DOWN does not make the screen brighter or dimmer.

I've added the voria-ppa-karmic repository and installed what I think are the right samung packages:

Code:
tariq@tk220:~$ sudo aptitude search samsung
i   samsung-backlight                         - Backlight support for the latest kernel on Samsung n
i A samsung-backlight-2.6.31-19               - Backlight support for Samsung netbooks             
i   samsung-scripts                           - Scripts for Samsung netbooks                       


and as some other people have asked for similar queries, here is the output of:

Code:

and

Happy to provide any further information - any advice on how to get it working would be appreciated!

Thanks,
