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.

The correct command is sudo shutdown -h now. Try this. Hope it will help.

I have no idea what I did but its shutting down fine now in like 5 seconds.

Now these are the steps I followed as provided in the link by tijybba in the comment:

  1. Type in terminal: gksudo gedit /etc/default/grub
  2. Find the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
  3. Change this to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
  4. Save the file and close the file.
  5. Finally, in terminal: sudo update-grub

But again it didn't shut down properly.

Next I logged out of the OS (not shut down) and then from the login screen I shut down and it shut down.

Then I started my machine again and then shut down from GUI works fine now.

Why not to try

sudo poweroff now

shutdown is different. It will help you don't stop services and update your system (as an example)

I updated the kernel to 3.5.0-4-generic and that solved my problem.

it may also be a setting in your BIOS.. you can typically enter these settings when initially powering up the system and pressing F2 or F1 (The actual key may vary depending on manufacturer and year of the machine) check for "POWER" settings particularly something that may set the machine to wake on a network wake command... I have seen this interfere with Ubuntu's ability to properly shutdown.

For the ones getting "CPU#X stuck for XXs" errors on shutdown/logout : I fixed this issue by installing the proprietary nvidia drivers from the "additional drivers" utility tool.
