Xubuntu cannot be shutdown using software

[Tipi Koivisto]

I have a Lenovo L520 that can be shutdown only by pressing power-button. Making a shutdown in every possible way from UI or command line the computer just freezes. I can even hear the hard drive shutting down. One thing I dont understand is that Linux Mint is based on Ubuntu and it does not have the same bug. Not in Mint XFCE 12 nor 13.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.6 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and leave the other tags. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I installed fresh xubuntu-12.04.1-desktop-amd64 and installed both as described at https://wiki.ubuntu.com/KernelMainlineBuilds . With the kernel 3.2.0-31 and shutdowns (see my P.S. section :) did not work.

I installed the Mainline kernel as adviced.

uname -a
3.6.0-030600rc7-generic #201209232235...

Shutdown still does not work. Boots beautifully with "sudo shutdown -r0".

HOWEVER something little different happens: If I do the shutdown as root and do "shutdown 0" the screen turns to black and freezes. If I however do shutdown from UI Application Menu or by "shutdown -P 0", it asks the sudo password and shows me the Xubuntu wallpaper and jams the same way. I mean the totally blank screen is something new. I don't if this is relevant information...

P.S. Is there some other ways I could still try to shutdown the computer? I've tried at least: "sudo shutdown 0", "sudo shutdown -P 0", "sudo shutdown -P 0", making shutdown from UI.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

Tipi Koivisto, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (1.23). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.
