Running 16.04 on an old PC desktop. Everything is fine. Then I leave for 8 hours. I come home and the hard drive is spinning/writing like crazy, but the desktop won't come up - it's black. I can see/control the mouse cursor, but nothing else. I have to hard shut down the box and reboot.
Have I been compromised by a botnet? How can I find out? Some other explanation?

Can you CTRL-ALT-F1 and get a shell? It may take a few seconds to switch if the CPU is maxed. I've seen desktop environments chew up the CPU and become unresponsive. What desktop are you using? gnome, unity, cinnamon?

A system which ran out of RAM and is heavily trying to swap might show the same symptoms.

I’m on Ubuntu desktop LTS. I’m only running chrome so not sure why memory would max out unless there’s a nasty memory leak. I’ll try the shell key command next time it happens. Thanks.
