    10.4 cannot shutdown

    Clean install of 10.4

    I select shutdown and it takes me back to the login screen. Trying to shutdown from that screen does the same.

    Any ideas?

    Re: 10.4 cannot shutdown

    Hello!

    I also had the same problem and solved it today...

    I had to read this page >

    http://wiki.ubuntuusers.de/Herunterfahren

    Sorry it is unfortunately in german... You don't have to read the above link if the following steps will help you as it worked out for me...

    This is what I did>

    1. Type in the Terminal

    sudo gedit etc/default/grub
    You are supposed to scroll down and find the line:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    in which the option "acpi=force" should be added in the line like that:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
    You should save the changes in your file and proceed tho the next step:

    Now you have to update the actual configuration to your system with this command in the terminal:

    sudo update-grub
    I have to mention that I am using Kubuntu 10.4 and had also the same problem with the previous version but solved it...

    Note also that I had to install on my desktop the button "shut down" from the widgets. (On the desktop right click and select "add widgets" option after unlocking the widgets)

    My computer never shuts down completely when I am using the button in KD Launcher but works perfectly with the button on the desktop. (shuts down completely)

    Same problem here on a clean install of 10.4 32 bit (last two times the problem showed up I used a second monitor with my laptop, don't know whether that's relevant). I don't have a etc/default/grub file, though.

    Hi

    I am sorry... Seems like I forgot a slash from the code....

    The right command is:

    sudo gedit /etc/default/grub
    Don't know if the use of 2 monitors is related.... Logically I guess not. If the computer doesn't shut down means that applications or hardware stay switched on and cannot be terminated...

    Or in my case, the computer needs to know that it exists the ACPI (Advanced Configuration and Power Interface).

    Check this out :

    Ok, I take that back: works sometimes, sometimes it doesn't (now also on another machine with 10.4 64 bit). Canonical guys, plz fix that, a 21st century OS should shut down without sudo tweaks ...

    I also had this problem. From the Terminal, enter the command 'sudo halt'. This should shutdown the system. In my case, after restarting, this also fixed the problem that other shutdown methods did not work.

    Still doesn't work on both computers. Only way I can shutdown is with

    sudo -h now

    everytime ...

    Same thing for me--both my desktop and my laptop. I hope the guys fix it soon. In the meantime, I guess I'll have to learn to use the terminal for shutdowns.
