After upgrade, my hardware switch for wifi (accessed by Fn + function key) stopped working. But, all other function keys to control display brightness, volume, mute have been working fine.
There are some pages on askubuntu.com which discuss the same problem that I have. But, they talk about re-installing broadcom drivers, etc. I checked mine and I seem to have a qualcomm device instead of broadcom.
