Ubuntu 8.10 Shutdown Problem
I am a newbie to Linux, and who has managed to solve a couple of problems with my installation (wireless LAN and sound). However, one item remains to be cured.
When Loading Ubuntu 8.10 Out of Box (via the free CD through the post) on a Dell Optiplex GX1 Desktop of some vintage (don't ask!), the shutdown feature does not completely power off. It just hangs at the very end due to some ACPI related problem. I say this because i also tried
sudo shutdown -h now
And it shuts down ok from recovery mode.
Having followed some excellent threads, my understanging is i may need to edit the /boot/grub/menu.lst file and perhaps add
acpi=force pci=noacpi
to the Kernal /boot.. line(s).
But several Kernals are listed. System Monitor stipulates i am running on 2.6.27-11-generic, so:-
A) Should they include both that end "quiet splash", becoming "quiet splash acpi=force pci=noacpi" (all on same line)
B) or should they include both that end "single", becoming "single acpi=force pci=noacpi" (all on same line)
C) and what about the memtest?
My menu.list file reads
************************************************** ************************
## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false
## ## End Default Options ##

I have tried several edit options to the /etc/modules file
apm

acpi=force
acpi=force pci=noacpi
but all to no avail.
Any help or advice would be much appreciated.
