I run a T520 Lenovo on Ubuntu and had similar challenges until I started to manually turn my GPU on and off. Windows and Mac have excellent drivers which automatically control GPU while Linux does not.
At least on Ubuntu if you have a Nvidia GPU there is a handy widget you can install so simply toggle the GPU but it requires a logout/login each and every time.
Just not the same experience as Windows but in terms of battery life it does the job. I get about 3x battery life when in Intel Graphics vs my Nvidia.
- gargravarr 10y agoThis would be my first thought, I also have a laptop with Intel and nVidia graphics. Have you tried Bumblebee? I have it installed, but I don't see much difference. I didn't buy my laptop for the battery life, but it'd be nice if it lasted more than an hour!
- ge96 10y agoI don't understand how if you turn off GPU, wouldn't your screen not work? I haven't heard of that before (not saying it's not true I just don't know)
