Hey all i have a new install of ubuntu 8.04 Desktop - all updates installed. Everything seems to run ok? although the entire system wont power off!!!
System runs through text on screen and ends with just
[ 5160.620402] System Halted
And hands there forever, some bits in the PC turn off, as i can hear them click off and less sounds comes out but i dont know what they are :S
Please help! this is the "family" PC for my mum and she isnt "computer friendly" and i dont think she will want to hold teh power button every time -__-

Could you try the suggestion here: http://www.understated.co.uk/2004/automatic-shutdown-in-ubuntu/
If that doesn't work you can try (especially if this is an old machine) to add the option acpi=force to the end of your kernel line in /boot/grub/menu.lst

I have one of those machines that has to either have ACPI turned off in the BIOS, or I have to boot with acpi=off.
My machine works good except it doesn't power off when I shutdown, just stops at "System Halted" with the power still on.
So after trying different things such as apm=power_off in grub.cfg / menu.lst, and apm in /etc/modules, etc. nothing was working for me.
What finally worked for me was a tip from this (http://www.brighthub.com/computing/linux/articles/39504.aspx) article by Michael Dougherty, where I booted with pci=noacpi in grub.cfg / menu.lst.
For Ubuntu Karmic 9.10, I made the following changes after making a backup copy of the "/etc/defaults/grub" configuration file:
sudo vi /etc/defaults/grub
Change the line
GRUB_CMDLINE_LINUX_DEFAULT=" acpi=off quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT=" pci=noacpi quiet splash"
then run this to apply the changes and rebuild your grub.cfg
After rebooting, my machine shuts down without issue.
Ubuntu GNU/Linux is awesome!
