I believe you can turn off the nvidia card with vgaswitcheroo: % cat /sys/kernel/debug/vgaswitcheroo/switch 0:+:Pwr:0000:00:02.0 1: :Pwr:0000:01:00.0 % echo OFF | sudo tee -a /sys/kernel/debug/vgaswitcheroo/switch OFF % cat /sys/kernel/debug/vgaswitcheroo/switch 0:+:Pwr:0000:00:02.0 1: :Off:0000:01:00.0
