Please guys, help me.
I installed Xubuntu 18.04 LTS in a Laptop DeLL Vostro Intel Core i3 2.1GHz 64 bits 4GB RAM.
But, when I suspend the PC, the system only wake up if I move a Bluetooth USB mouse connected to the laptop.
The laptop doesn't have a "wake up key". If the mouse isn't connected I can't wake up the computer.
Please, how to configure Xubuntu 18.04 LTS to wake up pressing a special combination of keys or pressing any key on keyboard?
