My PC doesn't shutdown from GUI

  • 772

Since at least a month, my 11.10-64bit PC doesn't shutdown anymore from the GUI. It simply freezes on plymouth screen. If I open gnome-terminal and type "sudo poweroff", it shuts down correctly.

This is very annoying. I don't have any relevant message in the logs. It simply stops at "The system will be halted"...but it doesn't power off.

    I have fixed this by adding the following line to the file /etc/default/halt:

    INIT_HALT = POWEROFF

  2. While that solution didn't work for me on Ubuntu 12.04, I was able to solve the problem in another way:

    I removed the Nvidia drivers, and the computer then was able to correctly shut down and restart.

  3. Actually if you want to shutdown and power off the machine, you should type:

    sudo shutdown -P now

    
-h:     Requests  that  the system be either halted or powered off after
        it has been brought down, with the choice as to which left up to
        the system.

-P:     Requests that the system  be  powered  off  after  it  has  been
        brought down.

  4. I had this problem. I updated grub and worked fine. Launch Terminal and type the following:

    sudo update-grub
