shutdown can't auto poweroff PC

Thanks for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description doesn't yet have enough information.
Please include the following additional information, if you have not already done so (please pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command 'uname -a' in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command 'dmesg > dmesg.log' and attach the resulting file 'dmesg.log' to this bug report.
3. Please run the command 'sudo lspci -vvnn > lspci-vvnn.log' and attach the resulting file 'lspci-vvnn.log' to this bug report.
4. Please also run the command 'sudo dmidecode > dmidecode.log' and attach the resulting file 'dmidecode.log' to this bug report.
For your reference, the full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks in advance!

Thanks.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

The 8.10 Alpha5 still can not poweroff.
All input device was disable, but power is not off.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

I have the same problem, but it seems to be a "gdm" problem, not related with acpi nor with "apm"... le te mexplain why:

If i tell it to hybernate it power off at end of it and when powered on again it resumes well.
If i tell it to shutdown it does not power off at end, but hey only if gdm was running when asked.

More detailed:
If gdm is running and i open a terminal window: no way to power off after shutdown, none commands: shutdown, halt --poweroff,... none works
If gdm is running and i press Ctrl+Alt+F2 to go to a console at full screen (text mode), but i let gdm running: no way to power off after shutdown, none commands: shutdown, halt --poweroff,... none works

But, if i press Ctrl+Alt+F2 to go to a console at full screen (text mode), and do:
#sudo /etc/init.d/gdm stop
So gdm is stopped then after few secconds i can confirm it is stopped with [ps -A | grep gdm], so i ask to shutdown with:
#sudo halt --poweroff
Or with shutdown,... all of them at end turns off the power and power off the notebook correctly.

I have seen on Internet a lot of forums on where they tell something about acpi=force, apm=power-off,... on /boot/grub/menu.lst also about adding apm to modules,... etc. none of that works for me.

And i found that if gdm is not running when calling shutdown it power off correctly.

When i was using Ubuntu Intrepid Ibex and Ubuntu Jaunty Jackalope it allways power off correctly, but when i updated to Ubuntu Karmic Koala it starts to not do the final power off when shutdown... now i know the cause is gdm running when calling shutdown.

Maybe it is related in some way with Kernel or with propietary ATI graphics driver...

Also i can see some near identical lines (more than ten) on /var/messages at the end of it with this error:
Kernel: Assertion fail in ../../../../../../../../drivers/2d/lnx/fgl/drm/kernel/hal_rs780.0 at line: 53

I do not know if such error is related with the shutdown problem, but is the last error logged and it is at end ot /var/messages no more lines after it... but i can only see it when not powered off correctly, if i do the trick of stoping gdm it does not appear.

Hope this can help someone to fix-it. Till them i will do the trick of Ctrl+Alt+F2 -> login -> password -> sudo /etc/init.d/gdm stop -> sudo halt --poweroff

Note:
After doing such, i powered on again and then after some hours of work i press shutdown by mistake (did not remember ro do the trick "stop gdm then halt --poweroff") but what surprise! it turns off the notebook correctly... so when i have time i will re-check if it was only once or can be reproduced.

I mean:
-Power On, then tell destop menu to shutdown normally and check if it turns off.
-If not force turn off, then turn on again, do the trick of stopping gdm and halt --poweroff, then power on again then tell destop menu to shutdown normally and check if it turns off.

But i will not have time till weekend, so if any one can also check that, it would be great.

SOLUTION THAT WORKS FOR ME:
Ctrl+Alt+F2 -> Login -> Password -> sudo /etc/init.d/gdm stop -> sudo halt --poweroff

Reinstall Initscripts from within package manager..... my experience....

Problem at shutdown failure at deactivating Swap.... Solved on Karmic Ubuntu

After over a month, desperately searching the INTERNET launchpad and wherever the search engines took me. I found the solution for my system. It is so simple I'm surprised none of the experts of the many many forums ever suggested it.

I forced my system off, i restarted to bios and power it off from there, tried to modify scripts and power down using various commands, yet it all failed, the hours & hours wasted. After almost giving up & waiting for the next major update to Lucid Lynx meaning months to shutdown my system properly (silly but well what can i say)

OK to the point.... which really really doesn't make me happy.... because of its simplicity.

I decided to find some shutdown tools in the hope that an advanced tool might help... So I Entered Synaptic Package Manager

Did a search... typed shut (& of course the results had a few tools for shutting down) or you can search initscripts which is my solution

1. I right clicked (sweet no command line)
2. Mark for re-installation (sweet so simple)
3. Apply & let the task complete

4. Reboot / perhaps shutdown & your computer powers off itself (You must love technology that turns off when you tell it to)

As a new user, why of why didn't anyone say i could have reinstalled that, i was thinking how to reinstall shutdown but didn't know the term i needed. I'd be interested to know, does this solve a
