Is it possible to power on Ubuntu over SSH or some kind of networking? I'm using Lubuntu on a laptop and want to switch on without opening the lid.
You need wake up by lan support by your laptop.
Wake-on-LAN enables users to turn on a computer across a network from another network device. It can be very useful in situations where computers are not all next to each other or there are a lot of machines. WoL works by sending a packet of data called a Magic Packet™ to the target machine. When the packet is received, the target machine's network device (Network Interface Controller or NIC) wakes-up the rest of the machine.
