I'm a new newbie Linux Mint user but I have a lot of desire to learn. I played a little with the shutdown command typing:
sudo shutdown +20
sudo shutdown -c
I then manually hibernate my pc because I had to go out. Now I'm back and I found that I could no longer turn on the pc because once Linux is started, I can see the desktop for 1 second, and then my pc shutdown.
How can I solve this?
