Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

My computer hangs at the very end of the shutdown procedure.
It gets as far as
"The computer will be halted immediately..." then a flashing marker _ and then it freezes.
I have to manually power it off by either cutting the power or pressing the power button for some seconds.
I have found a few threads dealing with the same or similar problems. Some suggest acpi problems, others some problem related to KDE and sound drivers. The latter seems to be more correct, cf. this thread. The solution mentioned there does not seem to work for me though. I have tried
unloading snd_hda_intel and snd_hda_codec both in runlevel 3 and 1 before shutting down, but it still won't power off. Some have also managed to shut down properly by disabling alsa e.g. in yast before shutting down, but this does not work for me either.
I use SuSE 10.2 with an intel DG965WHMKR motherboard.
'uname -a' gives:
Linux monster 126.96.36.199-0.5-default #1 SMP Fri Jun 22 12:17:53 UTC 2007 i686 i686 i386 GNU/Linux
ACPI has worked for me in the past too. I might suggest to rule it out in your mind, change your run level to boot up into console mode (no KDE) and shutdown form there. If it still hangs you at least know that there is a problem outside of KDE.
I tried setting acpi=force as a boot parameter with no effect. I also tried booting to runlevel 3 and then using
# poweroff to power the machine off. Exactly the same happened. This at least signifies that KDE has got nothing to do with my problem. It seems like it is an acpi-related problem. I checked the BIOS too, just to be sure, but found nothing useful there.
Also a friend of mine remembered that computers used to turn themselves off like this some years ago, before they managed to control their own power. You had to turn them off manually using the power button when they had shut down. I don't remember this but this is exactly what mine now requires. Another point in favour of acpi.
Any ideas ? I'm not very familiar with acpi. I had a look at /var/log/acpid but found nothing useful. It mostly looks like repetitions of this:
I really don't know - perhaps you could doublecheck if "PnP OS" is switched off in your bios - PnP is linked to ACPI for resource management. Otherwise you could try to manually remove all modules (do an lsmod to list the module names and remove each of them with modprobe -r <modulename>) just before powering off - it it still does not work you'll know that's not because of something hanging while removing modules during powerdown phase...
I guess this will have to be done in a very particular order, but I am not sure which. Can't seem to find any shutdown script either, since '/sbin/shutdown' is a binary file.
I had another look at my BIOS configuration, but there were actually no options mentioning PnP or Plug and Play.
Below is the output from
grep -i acpi /var/log/boot.msg >/tmp/boot.msg
It seems like PnP is up and working, but this is not my area of expertice...
There is a line that might hint at a solution towards the middle of the file though:
ACPI Exception (acpi_processor-0681): AE_NOT_FOUND, Processor Device is not present
I did a quick web search but got nothing particular out of it.
I am a totally new user of Ubuntu so I can't test OpenSuse but maybe Suse have a similar way of fixing this DSDT?
How much does OpenSuse and Suse and Ubuntu differ? if it works for OpenSuse then maybe it works for us too?
Distribution: Snow Puppy and Fluppy and Lupu frugal install
In the fedora community one user wrote this:
the problem occurs when I activate the desktop effects. I have been reading a lot of posts about desktop effects and shutting down problems and it appears that there is no solution. Do you know how to fix this?? I will keep my desktop effects off until I find a solution because it is really annoying not being able to shut down correctly.
