Ubuntu 14.04 won't shut down

[drphysic]

I have exactly the same experience that Steve J noted above, on an HP Compaq Presario V6105NR with the Broadcom WiFi card:
*Deactivating swap
mount: / is busy
*Will now halt
and all variations of halt & shutdown cause the same result. I had the identical experience with Lubuntu, which is why I tried running Xubuntu. This is on a clean install, reformatted HDD. Because the system does not shutdown properly, I also seem unable to install the correct driver for the BCM4311 WiFi card, so I am using a Netgear USB WiFi for now.

Lubuntu 13.10 did not have this problem on this machine. Any suggestions?

The solution for me for the " mount: / is busy", using a Compaq Presario V6105NR laptop, with a Broadcom BCM4311 WiFi card was the successful install of a working driver for the WiFi card, using the commands

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree

which did not work without purging the bcmwl-kernel-source. System now properly does a shutdown.

I have had the same problem, and I found the reason and the solution to it.

Cairo Dock causes this. It has it's own mechanism (button) to shutdown and it seems to override the native Linux Shutdown button action.

the solution is to remove the Cairo Dock.

sudo apt-get purge cairo-dock-*
sudo apt-get autoremove
sudo apt-get update
sudo reboot

When your computer reboots. Your Shutdown button should work.

I have the same problem but haven't found a solution to it yet. For me it isn't Cairo Dock at least cause that's not installed. I can see some lines of text on the display when I try to shut down but they disappear to quick to read, is the shutdown procedure logged somewhere so I can find out more about this?

sudo shutdown -r now

isn't working either

I found on my Dell e6400, change the following line in /etc/default/grub solve the issue.
GRUB_CMDLINE_LINUX_DEFAULT=""

It will print some messages when booting/shutting down, but it doesn't bother me.

[brian_woods]

yes, also worked for me thanks for help.

I got the same problem and this solution worked for me. I installed acpi for display information on acpi devices.

sudo -i
gedit /etc/default/grub

find the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and change it to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

save the file and close it.
now run

update-grub

now i think your problem solved.

And also if you are using cairo-dock please Removing Cairo-dock from the startup applications and try to shutdown from top panel.

Hello everyone. I found this thread when trying to figure out my issue. So instead of starting a new thread, I'll piggyback onto this one. I've already tried some of the suggested solutions here (acpi = force), but so far nothing has really worked. Basically, what is happening is the shutdown process seems to be working, but my laptop will not power down. It will get to the last step, display that it is powering down, but then just sit there. I have left it running like that for a while to see if maybe something would happen, but nothing. Strangely (or perhaps not strangely, I'm fairly new to Ubuntu), Ubuntu will restart just fine. It's only an issue when I shutdown.

One additional piece of information that may be useful (or probably vital): I dual boot with Windows 8. Recently, I suffered a stop error when booting into Windows (0xc000000f) where I was informed that the acpi.sys file was missing or corrupt. I used my recovery USB and was able to correct this issue through the recovery's boot repair. My guess is this is what caused my issue. Before this, I was able to shut down fine with Ubuntu 14.04. I'm not really sure what caused my Window's boot issue, but since I "fixed" it, I can't power down properly from Ubuntu. This seems like too much of coincidence to ignore. I did remove "quiet splash" from the GRUB_CMDLINE_LINUX_DEFAULT variable and during shutdown, everything returned [OK]. It just hung at the power down step (the last step).

Thank you for any help you are able to provide.

Hallo everyone!

I have the same problem since 2 years on one computer starting with (X)ubuntu 12.04, and now with 14.04 on 2 computers.
(X)ubuntu shuts down the computer, stops the HDDs, but does not power off.
Today I played around with the power management settings at the BIOS setup, and maybe I found a solution.

Just for the records, I got 5 machines in my network:
#1: Intel DP965LT mainboard, Core2Duo 2.4GHz CPU, 6GB RAM
#2: Intel DG33BU mainboard, Pentium DualCore 2.0GHz, 6GB RAM
#3: Intel DG45ID mainboard, Pentium DualCore 2.5GHz, 8GB RAM
#4: Intel D865PERL mainboard, Pentium4 2.8GHz, 4GB RAM
#5: ASUS Eee PC 1005PE netbook

Machines #3, #4 and #5 are always power off fine, no problem at all.

But machines #1 and #2 did not power off after shut down.

These two machines seem to share a nearly identical BIOS (AMI), and thus have the same bugs.
This problem seem to be ACPI (power management) related. So the relevant options should be in the section "Power" of the BIOS setup.
On both computers, the option "Wake on LAN from S5" was set to "Stay Off".

For this 2 machines, it turned out, setting "Wake on LAN from S5" to "Power On" seemed to solve the problem.
Of course, now this 2 machines can powered up via LAN, but the power off problem seem to be solved.

I rebootet both computers a few times and shut them down, to see, if it really worked.
So far, yes it did. But I'm not 100% sure, yet. In the past there were other solutions like "acpi=force" that seemed to work at first, but after a few days the problem was back. It was just luck it worked for a few shut downs...

So maybe someone can test this as well, and report here if it was a solution or not.
Also, please post infos about mainboard and BIOS, if you know. Maybe this can be of help, e.g. it only affects a certain type of mainboard or something like that.

Are u using Cairo-Dock? It seems like it is sometimes the cause, well in my case anyway since its on startup I think. But anyway I like Cairo so I just added LogOut applet and its working properly but off course its still not working from the upper panel. So in my case since its working fine from dock I dont care about the upper panel

Hallo!

No, I am not using Cairo-Dock. On all of my computers is now a fresh and clean install of Xubuntu 14.04, therefore Cairo-Dock is not even installed.

May I ask what kinf of computer do you use?
Is it a desktop or a notebook? If a desktop, what mainboard is it using?

Did you check your BIOS setup? Do you have the option "Wake on LAN" (WOL)?
How is it set? Does changing it, make a difference?
Please, could you check this?

On my two affected systems (Intel DG33BU + Intel DP965LT mainboards), I can reproduce the problem, if WOL is disabled they do not power off after shutdown. If WOL is enabled, both of them power down fine, always.

One of my friends also has an computer build with an Intel DP965LT mainboard. He had the same problem. Now, with WOL enabled, the system always powers off fine.
