I've been through all questions with the 'Shutdown' tag on this site - but this is different. I choose "Shutdown..." from the session menu. I then click "Shutdown" on the dialog that appears. Sometimes this does give me a shutdown and sometimes nothing happens and I am left with my desktop - which still works fine (that is, I can continue working on my computer if I want). Typing "sudo halt" from a terminal always works. I'd like to have shutdown work every time. Can anyone help? |

you can try experimenting with different kernel options. try one at a time and see if it has any effect like for example: acpi = force or acpi = off to try one out , when grub(with the selection screen of ubuntu-linux kernels, pops up after you have booted your computer, press the "e" button to edit your current configuration. this setting is not permanent over reboot so there is no risk of wrecking anything. if this works, and you want to make it permanent its time for a follow up question :) |

You may also track if there's not a program preventing you from shutting down. For example, I use a messaging client on my pc (QNetSoul, only for my school), and when I click on the shutdown button for the first time, it will only daemonize the program. Then my computer will not shutdown, even if I wait for an hour. But if I try it a second time, it finally kills it and effectively shutdown. In your situation, does a second click on the shutdown button turns your computer off? Or is it really prevented from shutting down until you do a |

Do a wright click on your session menu bar. Then there is a possibility to add something to this panel. So add the shutdown button who does appears. This always work. I had the same problem and now i use this button. |

You have basically messed around with the settings and this WILL fix but all you need to do is go into settings and try and fix what you have done! |
