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?

Emergency shutdown in a graceful way

  • Press both the alt and PrintScreen keys all the time and one of the R E I S U O keys one after another slowly.

  • If it is a laptop you might also need to press the Fn key like so:

    Press the three keys Fn and alt and PrintScreen keys all the time

    and one of the R E I S U O keys one after another slowly.

Emergency reboot in a graceful way

The corresponding system request sequence for reboot is similar.

O 'Off' is replaced by B 'Boot'.

  • Press both the alt and PrintScreen keys or

  • in a laptop maybe the three keys Fn and alt and PrintScreen keys all the time

  • The letter key sequence should be R E I S U B
