I am a newbie on Linux (really newbie) and I have started with Fedora Core 1, which I love. But I find very difficult to configure it and install new programs. Thanks to forums like this one, I've managed to put .mp3 support on XMMS, install java and Flash, which would have been impossible for me without this help.

Now I'm stuck with two things:

1- When I turn off my computer, it appears a black screen with "Killing processes", "Unmounting devices" etc., everything with a green OK. But the last message I receive is: POWER DOWN., and the PC is turned on until I press the big power button. Windows does it automatically, although with older computers and Windows it happened the same to me, it appeared a message similar to "Now you can safely turn off your PC". What can I do to automatize this?

2- When I insert an CD, I often can't eject it. With Audio Cd's it doesn't happen to me but if I put an .mp3 CD and play it, I can eject it. When I try to unmount, it appears a message telling me that it can't be unmounted, that it is on use, although I've closed all the apps that *apparently* use my CD. I've read some similar threads, and none has helped...

Well, I would appreciate any sort of help, but please remember I am really new on Linux, and I don't know quite anything.
THANK YOU VERY MUCH TO EVERYONE!!!

This is normal behavior. However, if you want to automate it, it's an APM (automatic power management) thing...which I don't know, so I'll leave that for someone else to answer. Oddly enough, my laptops shut down automatically, but my workstation requires a manual shut off.

I find this happens if you are still in the /mnt/cdrom directory....meaning, if XMMS is still trying to access those files, then it will say that the drive is busy. You need to make sure that nothing is actually currently reading or writing to the cdrom at the time you try to umount it....for instance, trying to umount from within the /mnt/cdrom dir... The command "eject cdrom" also works, once you unmount it.

For the shutdown problem:

If your computer's BIOS has ACPI support,

enable acpi by adding

acpi=on

to your kernel line in

/boot/grub/grub.conf

If your computer's BIOS has APM support,

enable apm by adding

apm=on

to your kernel line in

/boot/grub/grub.conf

For the unmount problem:

make sure no processes are still accessing your CD drive

fuser -m -v /mnt/cdrom That will tell you what's using the cd.

If you just want to kill them all do

fuser -k -m /mnt/cdrom


Cheers,

Forgot to say that fuser is not in bash:

/sbin/fuser ...

Sorry

Hi dkaplowitz & arthur1968!

Thanks for your replies.

Well, I am quite sure that nothing apparently uses it, as I close all the applications that were using that drive without unmount success. That's due to I'm a newbie and I'm not used to other processes opened or similar. The only thing I know it is that it's easier on Windows, and I'm just starting. Can't find anything open...


And refering to arthur1968, that could be the solution for shutdown problem. Checking in different forums, now I know I am using an SMP system (PIV with Hyper-Threading) and that could be causing this problem.
I tried several solutions on different forums but none worked, they told me to put "apm=power-off" on my kernel line. I don't know if it doesn't work or I can't recognise how to do it. I put it on GRUB's conf file in THE SAME LINE (is this OK?) that appears the word kernel (but not the lines that start with #, that seem to be just notes), at the end of the line.

And after, how do I know if my motherboard has ACPI/APM support, or whether has both (well, I really don't know what are they appart from they meaning, "Advanced Power Management" and "Advanced Configuration and Power Interface"). If is compatible with both (which I even don't know if is possible), which is better? Which line should I insert on that "unknown" line on grub.conf?

THANK YOU!!! :-)

You are most welcome.

I think 2 of the easiest places to check for APM / ACPI support are:

1 dmesg | less
This command will print out all the messages generated whilst the system is booted
Simply watch out for apm / acpi

2 When rebooting, go into your BIOS (usually pressing the Delete key / F2 or some other
key)
When inside the BIOS, just wonder around to see if you can find references to APM /
ACPI

Hei, arthur1968!

Your ACPI solution has worked for me. I've find in my BIOS config utility some ACPI settings and I have enabled all them, and added the line "acpi=on" and my computer now powers down automatically!

THANKS!
