Hello everyone,
I installed Ubuntu 10.04 on my notebook samsung R510.
Unfortunately, the fn keys to adjust the brightness does not work.
I then tried using the repository Voria, adding packages samsung tools and samsung backlight, as indicated in the main post of this forum.
Immediately after installation and restart the adjustment of brightness with fn 5 works great, to my great joy.
This morning I went to turn on the notebook and, again, the fn keys does not work anymore.
I tried reinstalling the packages given above but nothing at all ... now do not go ...
Advice on this?
PS - I also tried with Ubuntu v 10.10 but in this case the two packages just do not bring any benefit.
HELP!!!!!!!!!!

I've discovered thtat the reason of the problem above is that i've installed legacy drivers for my nvidia vga card...before everything was perfefct about brightness...any suggestions?
