So my PC has this issue that it freezes, then shortly after the display goes out and I have to hard reboot it. Luckily this is very seldom, but still annoying.
Somewhere in the past I have read, that one might still be able to remote connect to it (via ssh) and then check it or issue commands like a graceful reboot.
So how would I do that? (please explain for a noob). Ideally I want to use my phone for the connection, there are some ssh apps on f-droid.
