Please, I need help, I have a Dell laptop with intel HD graphics and a Nvidia gforce 730m. And the nvidia GPU is on all the time. I need to turn it off, is there any way? I tried to configure the Nouveau drivers and proprietary, and can not find the right one for my GPU, the 730m. Since I gave up. so I just want to disable the Nvidia GPU and only use the Intel HD graphics. Well, with this battery will last me more!
