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 :
lspci | grep VGAto see what number have my videocards
cat /sys/kernel/debug/vgaswitcheroo/switchto see what for videocard is active
but terminal says that it can't find locations of /vgaswitcheroo/switch. What must I do?
