I've bought my new precious netbook, Samsung NP-N148 few days ago and installed Ubuntu 10.04 on it.
Tried everything you advice to make my fn+f5 or fr+up work - it's hopeless.
I even edited a grub file, nothing.
Should I try to reinstall my OS? Because while I was remembering how to use consol i might have installed some unnecessary patches or smth...
And one more thing, If you know, how can I use this magic thingy http://www.aircrack-ng.org
? Couldn't patch my wifi drivers either...
