So I have an Intel 5500 as integrated GPU and AMD R5 M430 as Dedicated (Discrete) GPU, I installed Oibaf's Drivers and vga_switcheroo and I want to switch to the Dedicated GPU, forever.

Here's the output for sudo cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynOff:0000:0d:00.0

And when I do sudo echo OFF > /sys/kernel/debug/vgaswitcheroo/switch which is connecting to the Dedicated GPU, I get this error bash: /sys/kernel/debug/vgaswitcheroo/switch: Permission denied

How can I connect to the Dedicated (AMD) GPU, and do I need to connect everytime I reboot my laptop?

  • @ElderGeek it doesn't work, when I switch off lightdm, the computer freeze and I have no backlight. – sticsk Jul 25 '17 at 20:49
