Install the drivers:

sudo apt-get install fglrx fglrx-pxpress

then open the amd catalyst control center and disable the 5650.

TLP helps laptop reduce the ammount of power consumed in a much more efficient way than any other:

First: Uninstall laptop mode tools

sudo apt-get remove laptop-mode-tools

Then install:

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update 
sudo apt-get install tlp tlp-rdw

Finally start it:

sudo tlp start

  • Brask, +1 but would be nice if you add some link on what to do if the proprietary drivers fail to work --- it happens all too often, and it is not clear how to go back. – Rmano Apr 28 '14 at 16:35
  • it is also not work on my computer, when I install fglrx ,Ubuntu can't start. the screen display "run in low-graphic mode", I can not fix this problem, so I come back to 13.10 @Brask – zee_h Apr 30 '14 at 14:47
