I have Asus U41S notebook with 2 wideocards, Intel HD Graphics 3000 and GeForce GT540M. I want to turn off the GF videocard, and work only with Intel.

On the internet I found out how to do this with vga_switcheroo :

  1. lspci | grep VGA to see what number have my videocards
  2. cat /sys/kernel/debug/vgaswitcheroo/switch to see what for videocard is active

but terminal says that it can't find locations of /vgaswitcheroo/switch. What must I do?
