Ubuntu – Ubuntu 12.04 does not Shut Down at all and gets Stuck on 3 or 4 dots

Ubuntu 12.04 does not Shut Down at all and gets Stuck on 3 or 4 dots.

I am using a PC with Pentium 4 processor, 1.9GHz, 1GB RAM.

I tried using the command sudo shutdown now, but it gets stuck again at the Logo screen with dots.

And none of the answers seem to help me here. Please help with a gentler solution to shut down.

But restart works fine, the problem is only with shutting down.

To shut down and power off from the command-line with shutdown, the correct command is actually:

sudo shutdown -P now

However, if that doesn't work, press Escape when you first see the splash screen with the dots. That should show the messages "behind" the splash screen. Then update your question (by editing it) with the full and exact text of the messages you see.

By default, the latest ubuntu install (12.04.2, and few others behind) hides messages and shows a nice animated image (splash) in a fancy resolution.

To make sure to view the console and possibly see what's hanging behind that dark screen:

/etc/default/grub (edit & save):

# find line below and put a # in front of it
# GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
# and put this one:
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"

Now update grub boot entries with these new defaults:

you@yourmachine:~$ sudo update-grub

And at your next start/shutdown process, you should see message lines with [ OK ] or [ ERROR ] or something wrong following it's title:

* Starting network shares                   [ OK ]
* Starting mysql server                     [ OK ]
* ...later when shutting down...
* Stopping mysql server                     [ OK ]
* Not Stopping something like it should     [    ]

nomodeset: You usually can toggle between the splash screen and the console messages with Esc key, but some video cards or lack of drivers can't handle the mode/capacities the boot process is using. nomodeset ensures it's using basic common capacities and makes sure you see messages (provided you don't press ALT-F1 to F7 during boot/shutdown to view other terminals than the one used for services startup/shutdown).

Edit: You can also try without nomodeset if you run into troubles starting X. GRUB_CMDLINE_LINUX_DEFAULT=""
