I have installed ubuntu 16.04 LTS version using a bootable usb. It has given me a lot of grief.

Earlier it was not showing me the login screen, I resolved it by disabling secure boot option in the BIOS.

Now, the os is not restarting, whenever I click on restart it gets stuck. However, shutdown is working perfectly.


  1. Following command doesn't work, the machine hangs after executing the command:

    sudo reboot

  2. Even ctrl + alt + F1 doesn't work on the login screen, it doesn't show me the console.

  3. I cannot even logout from the system.

    Welcome to AskUbuntu! Could you please try to reboot with sudo reboot and dbus-send --print-reply --system --type=method_call --dest=org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Restart? What happens when you do that? Please edit your question to explain what you did and what happened. Thanks. – David Foerster Sep 11 '17 at 11:23

I tried the following command to resolve all the issues:

sudo ubuntu-drivers autoinstall
