Comment 44 for bug 173366

I have similar problem with my Vaio vgn-s59cp/b, the Fn keys used to work in ubuntu 6.06~9.04, however, none of them work in Ubuntu 10.04. here is some information I can provide:

/lib/udev/findkeyboards
AT keyboard: input/event3
module: input/event5

sudo /lib/udev/keymap -i input/eventX
and press Fn+F2~F7, nothing happens. however it do recognize the keys such as esc/enter, etc.
