I am new to using Ubuntu on a laptop (and thus am learning how to do all the configurations necessary for power management - which can be forgotten when using a desktop).
I have Nvidia Prime installed and have the Nvidia x server set to adaptive. However under the prime profile it says that the Nvidia GPU is selected always (even when I am doing nothing but showing my desktop wallpaper). So I switched to Intel GPU and then went to look at the Nvidia X server and all the options (e.g. adaptive) can not be found.
How do I get my computer to switch GPUs so I can have decent battery life.
I have a dell XPS 15 with a whopping 97 wH battery... and 3 hours hours of battery life on Ubuntu even with TLP.
