Ubuntu doesn't shut down

  • 772

Recently my PC cannot shutdown (Ubuntu 16.04). Each time I have to turn it off manually using the on/off button on the computer. Restart works fine.

When I try shutting down the usual way, the screen remains blocked as it will shut down in a few seconds. A violet screen with a little Central "ubuntu" word with 5 dots below it, four lit red, one lit white. Running sudo init 0 and sudo shutdown now have the same result.

However, I can restart and open the PC with Windows 7 and then shutdown regularly. What should I do?

shutdown 16.04
