I installed ubuntu 18.04 on a lenovo legion y540 laptop with dual hard disks. ubuntu 18.04 on 128GB m.2 and windows 10 on the second drive-ssd. When I installed ubuntu I chose 15GB swap space. The machine has 16GB ram.
Problem: When I open system monitor application, it shows the system as 2gb of swap but on the 'disks' app, it shows the swap as 15gb as I allocated. Why is this discrepeancy?
