****Full tutorial for doing this on a VGN-FS laptop can be found here!****
This is the best source of info I have been able to find on how to get the Special key’s working on the FS laptop’s.
The forum is for the Gentoo distro mainley, but there are also a couple of fixes for other Linux distro’s too.
It might be worth me adding that I’ve forwarded this forum to the Ubuntu dev’s in the bug report here. Hopefully (fingers crossed) they will put the info to good use & add the support needed to Dapper.
