Ubuntu 12.04 is not doing normal shutdown

  • 772

I have installed Ubuntu 12.04 on my laptop.Every thing is working fine.But from last two days I am facing a problem and that is when I am going to shutdown my system,it is showing the shutdown process but it is actually not doing shut down.The screen is reaming like that for many time then I am doing the forcibly shutdown by pressing the start key of my system.Can someone tell me what is the wrong going on?Any help and suggestions will be highly appreciable.

[update]

When the shutdown process was going on I just pressed the esc key and it showed the error message like this

modem manager[878]:<info>Caught signal 15,is shutting down...        [Fail]
shutdown

  1. The problem is in NVIDIA driver. You have to go to System Settings --> Additional drivers and there you have to mark and install NVIDIA accelerated graphics driver (post-release updates (version current updates).

    The Recommended driver above it causes the problem.

  2. I do not think it is related to the graphic card, I have an intel chipset and same annoying bug! For now I installed terminal emulator "Terminator" and created a launcher with the following command in it:

    terminator -e "sudo shutdown -h now"

    , it works everytime and will help me wait for the right update!
