I gave a job candidate a short coding test using a guest session on a Laptop with Ubuntu. When I opened the guest session I saw the message:
After the interview I closed the lid of the laptop to transport it to another room. I did not explicitly log out. When I opened the lid, of course, it had logged me out of my session destroying all the data. Great.
This is bug, right? Unless the user expressly logs out or switches session, it shouldn't destroy data.
How can I recover any data from the hard disk?
