Need help troubleshooting shutdown

[hwkdriver]

Hello!

I am looking for a bit of help and guidance to troubleshoot shutdown problems. First I would like to know if anyone has good location of some documentation on the whole process of how to troubleshoot shutdown issues.

Secondly, here is my current problem. Occasionally when shutdown Ubuntu the splash screen will come up then disappear. Then a back lite black screen will appear and normally this goes away and the computer is immediately shutdown. But on occasion it will just hang at this back lite black screen and never shut down.

I am running Ubunutu 9.04 Desktop on this machine with all current updates.

Thanks for the help!

Hi hwkdriver
Check in your /boot/grub/grub.conf ( must be root to edit this file) and make sure that your acpi=on and not acpi=off in the settings. If it is off it will not take control and actually power of your unit. Hope this helps. Cheers...

I believe that you were refering to the menu.lst file. Otherwise, there is no grub.conf file there. If so there was no acpi settings to modify. Thanks for any further help!

Hi hwkdriver
I am running Fedora 11, and the distros vary abit.. Try adding acpi=on in the menu.lst as shown below:

title Fedora (2.6.29.6-217.2.16.fc11.x86_64)
root (hd0,0)
kernel /vmlinuz-2.6.29.6-217.2.16.fc11.x86_64 ro root=UUID=0268b328-d6b0-4731-81f0-401c88057f61,acpi=on rhgb quiet
initrd /initrd-2.6.29.6-217.2.16.fc11.x86_64.img

Your code may appear a bit different but the'acpi=on' may help. Sorry about the grub.conf file as it is possibly Fedora specific. Make a copy of your current menu.lst before making this change in case things do not help. 'cp menu.lst menu.lst.old' or something. Since changes to the boot menu can be dangerous caution should be used. If you are at all uncomfortable about changes to the boot menu you may elect to live with the issue. You may hang the system if syntax for your distro is not correct. Cheers...

Here is the adjustment to the grub file:

title		Ubuntu 9.04, kernel 2.6.28-15-generic
uuid		d804bbc7-2692-4d0d-808f-b27f0faeb080
kernel		/boot/vmlinuz-2.6.28-15-generic root=UUID=d804bbc7-2692-4d0d-808f-b27f0faeb080 acpi=on ro quiet splash 
initrd		/boot/initrd.img-2.6.28-15-generic
quiet

I noticed I did not add that this machine is a dual boot with Vista.

After adding this I still got the hang on shut down. Any other possibilities?

Thanks!!

Hi hwkdriver
Does the machine always shutdown, without issue, when you boot into Vista? One way to ensure a proper shutdown is to, as root, run #shutdown -P
Try this process a few times and see if it works. Not a GUI solution but if it works maybe we can do something about that.
On other question: Have you looked in the BIOS settings to see if acpi is set to be on?
Give this a try and post back. Cheers...
