http://www.kubuntuforums.net – I have a laptop Samsung RV408 with 8 Gb RAM and I need to control the brightness of the screen and other functions using the keys (Fn) in Saucy 13.10 ??? The latest version that I can install from the repository ppa:voria/ppa (https://launchpad.net/~voria/+archiv...filter=quantal) without any problem is the version 12.04 and 12.10 to 13.04 version I had to edit the repository by changing Quantal Raring to install but now that does not install or editing. In what way I can control the brightness of the display and the function keys (Fn)? :scratch: ESPAÑOL Tengo una laptop Samsung RV408 c (HowTos)
