Ubuntu – Ubuntu 14.04 wont shutdown or reboot

14.04shutdown

Have Ubuntu 14.04 installed on a Toshiba Satellite S50 with Windows 7. Offnote: Was experiencing freezes with the proprietary nvidia driver so I switched to the Nouveau driver.

My ubuntu will not shut down or reboot. I try typing 

sudo reboot -h -q now

among other variations as well as shutdown but I get other outcomes:

  1. It closes x and freezes at the terminal with a _

  2. It closes x and I get a terminal: 

    wait-for-state stop/waiting

* speech-dispacher disabled; edit /etc/default/speech-dispacher

And I get a root prompt.

Side Notes: Using Gnome Desktop, lightdm

Why am I unable to shutdown or reboot?

For others with this problem, I was experiencing the same thing. I didn't even have to try this (which was my "okay, i'll deal with it this way" option).

After a Google search I found another solution, which is to go into /usr/share/dbus-1/system-services and rename the file org.freedesktop.ModemManager1.service to anything else. I called mine thisfilebreaksmycomputer.service. I had to sudo the mv command to do this.

Upon renaming I was able to successfully shut down and boot up without any issues!
