Your metabolic rate can be several times higher in a pool or other body of water than it is on land without any exercise at all. Body heat is lost at a much higher rate when you are submerged in water and your body will burn more fuel to maintain core temperature.

There have been issues with multi monitor placement, primary display setting etc that can get pretty fiddly to solve - seen it with different distros over many years of NVIDIA proprietary driver use.
