Public bug reported:
Bug reported as per instructions from Christopher M. Penalver (penalvch)
Shutdown and Reboot failure on Dell XPS/nVidia 295.49/Ubuntu 12.04
Sometimes "sudo reboot -h now" works, sometime not.
Had the same problem on 11.10 so I didn't install nVidia driver on a
clean 12.04 install but problem was still there. Installed the nVidia
driver because it didn't make a difference.
Tried stopping various unity processes using "system monitor" before a reboot
(sudo reboot -h now) and this seems to work but it is terribly inefficient
The unity processes stopped:
unity-files-daemon
unity-applications-daemon
I then tried it using the ubuntu "shutdown" button after stopping the
same processes and it also seems to have worked
