I've just started using Ubuntu (or any Linux distro, for that matter). I just bought this computer (Dell Inspiron 5593), and I've installed the latest Canonical LTS version of Ubuntu (20.04).
My battery life is, quite frankly, abysmal. I was told the battery should be lasting 7-8 hours, but it's barely lasting 3. I assumed it might be a driver issue with the NVIDIA GPU, and, as per the instructions here, I examined the "Additional Drivers" tab, where I saw that the "Using NVIDIA driver metapackage from nvidia-driver-440 (proprietary, tested)" radio button was already selected:
So now I'm at a bit of a loss as to what's going on. Again, I'm new to Ubuntu and to Linux, even though I do have some rudimentary knowledge of the command line--does anyone have any recommendations of next-step diagnostics?
