Linux Mint 16 Petra 32bit(Xfce) - Sony Viao (Laptop) Model: VGNFS980
I have no 'function key' functionality to control brightness...
When I first booted the live version, the brightness was OK. Upon finishing the actual installation, the screen was dim. No proprietary Drivers are Found in 'driver manager'. Also, I've tried the Grub edits from several tutorials, with no luck.
