Bug Description
After the update from 11.04 to 11.10: when I shut down the pc sometimes it goes back to the login screen and then I have to do shutdown there which works well then.
Sometimes the pc shuts down but ends with the ubuntu splash screen and gets stuck there.
The issue may be driver related: I use the AMD/ATI FGLRX graphics driver.
I have a second pc where I also did the update to 11.10 and there I have no problem at all but I don't use the above driver but the NVIDIA graphics driver.
Both pc's have Ubuntu 11.10 64-bit.

I also submitted a bug report, but have now marked it as a duplicate of this one.
I don't think this is related to the graphics driver as I am using the generic Ubuntu driver and have this issue. In fact, I dual boot Ubuntu and in Ubuntu Studio 11.10 this bug does not occur, but in standard Ubuntu 11.10 uprgraded from 11.04 I get this bug.
Shutdown bugs seem really hard to track down as logging is tunred off before the bug occurs and the damn Plymouth screen kicks in hiding a lot of the shutdown messages.
I have noticed by killing LightDM I can sometimes see some more of the shutdown messages and it is clear that this error is because a process is failing to shutdown successfully, preventing the pc from shutting down. I did once see an error message saying lightDM didn't shutdown, but that was only once....

Same problem on two different PCs, a desktop with intel and a laptop with nvidia graphics, so I don't think it's graphic driver related. I can see the shutdown screen and the dots under "Ubuntu" keep on blinking. If I hit Esc I can see the last msg is "All processes ... within 2 seconds"
Both my PC have 64-bit installs.

I have the same problem, every shutdown hangs. I tried this before shutdown and it worked correctly:
- killed nm-applet from System Monitor
- sudo service network-manager stop
- sudo service networking restart
Maybe the only command needed is 2°, stopping the network-manager service.

From the clean installation of 11.10 64-bit I have the same problem. So far I wasn't able to shutdown/restart my laptop HP 4520s (if it helps). I also tried the suggested command above, no success. Even if I get to TTY1 (or any) and try to sudo shutdown the pc just hangs up on purple ubuntu screen. When I kill lightDM, it hangs up too. Well, if I can be of any assistance here, sending logs or so, plase tell me, for the thing is becoming a pain in the ***, yes there.

I use a USB mobile internet modem and this issue occurs whether or not it has been plugged in and active at some point during my session, so I do not think that it is modem-manager causing this. I can restart if I have not logged in without a hang, but if logged in, whether network-manager has been stopped or not, I have a hang at shutdown and have to shutdown by holding the power button. This has occurred since upgrade to 11.10 via normal upgrade procedures.

Are you certain that it is not installed? I also did not use it, but
its mere presence was sufficient to hang the shutdown. Since
uninstalling network-manager, I have not seen the issue pop up again.

Using poweroff --force does shutdown my laptop, but I worry that might not be a graceful or safe way of doing so...
It is clearly an issue with some process not responding correctly to the request for it to quit.
If it is of relevance, I also experienced the Xauthority issue as part of the upgrade (inability to log in to account due to LightDM borking some permissions somewhere during the upgrade), so I wonder if what caused that also caused this issue...

Just for the record: I see this problem on two different machines (a desktop and a laptop): both machines shut down just fine before the upgrade to oozing ocelot. Since the upgrade, the shutdown hangs. In the hung state, the Ubuntu logo is visible, underneath there are three red dots and two white dots, and the machine doesn't react to key presses (e.g. switching virtual consoles seems not to work).

Shutdown my notebook only worked the following ways:

Stefano Bagnatica (thepisu) wrote : | #27 |
I also have done some tries, and can say that stopping network-manager does not help, instead the computer shut down correctly if I do: sudo /etc/init.
So reading many comments it seems a problem related to networking engine in general.

I have an HP dv6 1350us laptop, which is a couple years old. I had originally installed Ubuntu 11.04 as a fresh install, and then upgraded to 11.10 via going to a dev branch originally and updating periodically. When we got near the RTM release date, this started happening to me as well and hasn't gone away. I suspect it has something to do with ACPI and here is why: if the laptop is unplugged and is running off the battery, it has never happened to me. If the laptop AC adapter is plugged in, it happens most of the time.
rupert (r-plumridge) wrote : | #29 |
I suspect it is more complex than that, since I get it all the time regardless of it being plugged in or not. It is clearly down to a process failing to exit correctly, an process we are all running but isn't necessarily common in the default 11.10 install as not everyone has this problem.
We need to list what is non-standard on our systems. For instance I mount various drives via NFS at boot, which might be an issue...

I'm pretty sure now this is an issue with a network drive tool, most likely rpcbind, since I see an error thrown by rpcbind when my laptop fails to shutdown.
I also see the following two errors when my machine boots up:
Nov 24 20:19:57 netbook rpcbind: Cannot open '/run/rpcbind/
Nov 24 20:19:57 netbook rpcbind: Cannot open '/run/rpcbind/
I wonder if these missing files are causing the shutdown issue. I found these by simply
cat /var/log/syslog | grep rpcbind
Can some ubuntu devs PLEASE start to respond to this issue so we can fix it, OK, it might not be a bug of stock Ubuntu, but it is a bug of the upgrade......

Just type this in a root command prompt
cd /etc/init.d && update-rc.d -f umountnfs.sh remove && update-rc.d umountnfs.sh start 19 0 6 .
It worked for me. It is actually moving the order of umountnfs to call it before sendsigs so the nfs share are unmounted before killing all the remaining process.
It's not a bug correction, but it works.

I think there is a major misconception:
halt (or shutdown -h) will halt your PC whereas poweroff (or shutdown
-P) will power it off.
The shutdown -h behavior has changed since Natty, but according to the
man page both variants are valid.
Easy fix: Use shutdown -P and your system should power off again.

@Thilo-Alexander Ginkel (thilo.ginkel) just to confirm, this issue occurs when the user tries to shutdown normally via the GUI (i.e click on the cog > Shut Down > Shut Down), not when issuing terminal commands, although the issue is still evident when trying to shutdown via the shutdown -hP command for example.

I dont think it is the same bug as https:/
I have tried to kill all wireless devices and programs and disable modules. Nothing seems to work.
Yesterday I installed 11.10 Xubuntu again (to Lenovo S205) with the same results. GUI or not, shutdown or poweroff does not work.
When I do "shutdown -r 0" as root boot is executed nicely. Says "*Will now reboot" and reboots.
On the other hand when I do "shutdown 0" as root the last message in standard output is "*Will now halt..." and then comes Mr. Freeze. I can even hear the hardrive shutting down but then it just freezes.
Therefore I think the problem is in somewhere between Halt and hardware.
I have also tried to print messages from syslog, dmesg, kern.log when shutting down, but there seems to be nothing connected to this problem. There are a lot of similar kind of problems with 11.10 so hope this will be fixed soon.

That's a different issue. "halt" does not guarantee that the system is
powered off; to get this you need to use the 'poweroff' command or 'shutdown
-P'.
If you call 'shutdown -P' and the system still does not power off, that's a
(separate) bug. But not powering off in response to 'shutdown'/'halt' is
allowed behavior. I'm not sure *why* the behavior changed, and maybe we
should revert it for future releases, but for now please use the explicit
command.

My laptop is a Asus N61J series. I have upgraded from Ubuntu 11.04 to 11.10 and this problem appeared.
It hands when shutting down or rebooting. Usually, one or zero of the circles get filled on the splash screen and it just hangs there. Sometimes it's actually does shutdown successfully, but it's rare (1 / 3 maybe).

I have this problem on a clean install of 11.10. AMD Sempron on Biostar 790 mobo. I installed 11.10 from a live CD of about a month ago, it worked fine, then updated and the problem appeared.
The machine sticks at the Kubuntu shutdown splash with the "balls" active, nothing else happens. I can't get a terminal or response to any key presses, but sometimes ctrl-del will bring up a full screen activity log. Usually (not always) it's stuck at trying to shutdown modem-manager with signal 15, there is [fail] in red on the RHS against it. More random pressing of ctrl-del or ctrl-alt-del gets it moving again, line at a time, until eventually it shuts down, BUT, it always reboots. No combination of shutdown -h -P -r now makes any difference, it ALWAYS reboots.
I tried to kill modem-manager with sudo kill (process ID) before shutting down, but it wouldn't die.
The only way to turn of the machine is the power switch, or sudo poweroff --force

Not sure if this is important but though I would add my experience.
I had the same issue using a desktop with 11.10, and a Tenda W54P wireless PCI card.
For unrelated reasons I removed it and started using a USB dongle (Edimax EW-7612UAn) and the problem went away.
With both of them I used the drivers which came with ubuntu so I would assume it is a problem with one of the wireless drivers. Unfortunately I have no idea how to check which driver was being used previously as I dont have the card anymore.

However, when I switched to a TP-LINK TL-WN321G (stolen from my other near-identical machine, which doesn't have the problem) the problem went away.
I don't have any network drives. Just starting up ubuntu with the edimax plugged in (and connecting automatically to my WPA network) is enough to cause the shutdown problem.

I recently got my card sort of fixed and therefore stop using the usb connection. So are any of you guys using usb network devices or some other type of usb device that would cause this. Although it does seem to be centered around network issues by the looks of everyone else's posts.

I tried Alex's fix (disabe session management in compiz) and it may have made the hangs less frequent, it has not solved the issue on 3 different sets of hardware.
As an aside, some dual-boot testing on a couple of machines with Mint 12, using Cinnamon and Gnome Shell sessions results in zero shutdown hangs. AFAICT the issue lies in something exclusive to "genuine" Ubuntu/Unity and the way it's doing a shutdown.
Steve Langasek (vorlon) wrote : | #80 |
This big report is being used to track a known issue with hangs on shutdown caused by an interaction between network-manager and network mounts on shutdown; and that issue should be fixed now in 12.04, so I'm closing this report.
If you are experiencing hangs on shutdown in 12.04, please file a separate bug report for your issue so that it can be investigated separately.
