In order to get this behavior we can have a solution as described here: http://ubuntuforums.org/showthread.php?p=11867169#post11867169
** Description changed: I have a laptop with two video cards: > lspci|grep -i vga 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] (rev ff) I have looked around and I saw there is the vgaswitceroo module which can be used in order to turn on/off unused graphics cards and also switch the enabled one (albeit with X restarting). - My question is, why Ubuntu is not powering off the unused card by default? + I believe Ubuntu should power off the unused card by default. The default behavior is to use the Integrated GPU (Intel) but still keeping the Discrete GPU (ATI) on. This can save up to 10W in my laptop, which is at least 50% more battery power previously wasted on keeping an unused GPU on.
