Hi I'm trying to change my integrated graphics card to my discrete graphics card (Nvidia GeForce 540m) and when I use the vgaswitcheroo method, I can't access the file doing this:
$ls -l /sys/kernel/debug/vgaswitcheroo/switch ls: cannot access /sys/kernel/debug/vgaswitcheroo/switch: Permission denied
This is the link to the guide on using vgaswitcheroo I'm using: https://help.ubuntu.com/community/HybridGraphics
I'll be using Nvidia Unix Drivers because I'll be playing with the graphics card.
Any help? Thanks.
Ps. I'm new at Ubuntu, any help would be appreciated.
