I want know how to disable discrete graphic in Ubuntu 14.04 ,my computer's gaphic cards are Intel and ATI 5650. I only want to use the Integrated card because the temperature of computer can stay low.
1 Answer
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.– RmanoApr 28, 2014 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_hApr 30, 2014 at 14:47
