The decision to mark the thread as solved or not is the OPs alone. Usually a solved thread means that a proposed solution in the thread or something the OP did solved the OPs problem. While still a bug, the OPs problem is solved.
Note that the solution to the OPs problem can and not always will be the solution for other people.

My 12.04 system with a Nvidia card shuts down fine, the one with an ATI card won't shut down without using the rocker button on the power supply. And yes I know this can create problems on the disk but it's the only way to shut it down once it hangs.
Suspend works though, otherwise I'd be reinstalling 11.10.
Just saw the post about logging off first. When I do that the system shuts down fine.

This may help some with the shutdown issue. I have an ATI card and just installed 12.04 after using 10.10 Maverick until the end. I have only been a Ubuntu user for a year now, switching from Windows. I have been very impressed by Maverick and was initially by 12.04 but after some updates got the same shutdown problem. I tried all the suggested methods and initially logging out then shutting down worked but after a while that too froze at the Ubuntu splash screen with the 'lights' freezing. This began to happen every time regardless of what method I used. I was using Unity but tried switching to Gnome 3 however the problem persisted with every shutdown after being logged on for more than about 10 minutes. I finally installed Cinnamon 1.4 and have managed eight problem free shutdowns from the Menu after long hours switched on. I also really like the desktop which has excellent workflow. This was how I installed it, taken from some web site:
sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
sudo apt-get update
sudo apt-get install cinnamon
This to me suggests it is not specifically a kernel problem or a graphics driver problem but at the core a Gnome problem or maybe the way Gnome is currently interacting with these that Cinnamon does differently, since it is a Gnome fork. Another test would be to see if the problem persists using Mate 1.2, which is a Gnome 2 fork. So luckily, fingers crossed, I've been saved from weeks of wasted work setting up and configuring Ubuntu 12.04.
I found this to work out for me. I'm also on a dell 1720.

I have the same issue. I have two D630s, one running 12.04 with Unity and another running 12.04 with Gnome Shell.
When using Gnome Shell with the post-release updates driver I was unable to restart, on reverting to the version-current driver the system restarts normally.
When using Unity with the version-current driver I was unable to restart, on updating to the post-release updates driver the system restarts normally.
After changing the driver a restart is required for the new driver to kick in. This will be a manual restart but from then on your system should restart normally again.
Hope this helps anyone with the same annoying problem.
OK boys I think I might have a solution to your problems because I had the same problem on numerous distros when using NVIDIA drivers and it took me about 6 months to figure out what causes the problem. The freeze on reboot/shutdown doesn't happen with the Nouveau drivers but those are still not good enough to me. Although they're getting better.
So anyway, it is the boot splash that causes the problem. What you have to do is open your file manager as root. For those who don't know how to do it, you open the terminal and type sudo nautilus or su - c 'nautilus'. Nautilus is obviously just an example , so if you're using thunar or pcmanfm you type in su -c 'thunar' etc etc.
Now, you go to etc/default/grub and you look for the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
and you change it to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
Then you look for the line:
#GRUB_GFXMODE=640x480
and you uncomment it and change the resolution to the actual resolution of your screen.
(Mine is 1366x768)
Once you do that, you add an additional line right under and it goes like this:
GRUB_GFXPAYLOAD_LINUX=1366x768
So when you're done , everything should look like this:
GRUB_GFXMODE=1366x768
GRUB_GFXPAYLOAD_LINUX=1366x768
Now you save it, open a new terminal window and type in sudo update-grub
You reboot and that's it.
Obviously you won't have plymouth anymore but console output instead. However I think it's definitely worth it and I rather have working NVIDIA drivers without splash screen than the other way around. This solution works for me and it works for all the Ubuntu based distros. I hope it will work for you guys and let me know if it did. This was really bothering me for a long time
