I have Ubuntu set up on this laptop as a dual boot. The problem I am encountering, and this problem has been the same since day one is that when I go to reboot or shut down Linux it will go to a black screen then hang...

The hard disk still spins. I also have Windows Vista installed and have no issues rebooting or shutting down,

Now Instead of using the GUI in Linux to shut down and restart I also tried doing this through the terminal using.

sudo reboot 

and it is also getting hung up.

Usually I can find solutions to my problems via the Ubuntu forums, and yet for this issue they don't seem to be very helpful.

Has anyone experienced a similiar issue, or can someone shine some light on the issue as to how I can fix it.

My Linux expertise is novice. Actually speak slow and clearly as I have A.D.D and will be more than likely thinking about why I still can't get my VB issue resolved.

ACPI issues! It's gotta be.

Where's it hanging? Like... What's do, in detail?

What happens if you issue the three finger salute while it's hung up?
Can you manually issue the shutdown command?

sudo shutdown now -r

I doubt that'll do anything different, but it's worth a shot to say we've tried that.

When I initiate the shutdown, Linux goes off, and then screen goes black as if it is just waiting for the hard disk to stop running.. this never happens, it is hanging there both with the reboot and shutdown process.

I even went into the grub and put reboot = h after the kernel command in the grub as suggested in another forum, this did not work either.

Well this actually worked. It rebooted my laptop however I guess it doesn't explain what is hanging it up. Or how come that is working and not sudo reboot.

Wow, I can't believe Linux is actually giving you problems!
Maybe you should install Ubuntu security patch 90847552 Bug Fix for Shutdown Problems? (sorry, just had to through that one back at you! )

What does it say on screen right before the screen goes black?

lol - I had a feeling this would be coming, rofl.

My first real issue with Linux,

I guess what is making it so ironic is that Vista (the OS I despise, has not given me a single problem. I have had two minor issues with Ubuntu. The code::blocks issue, which was just a minor configuration issue. And this reboot issue.

[Nykc]

I just got to thinking, in my grub file I reset the boot preference to make Linux the number 1 choice and haven't rebooted since. Could this have been a problem. When I installed Ubuntu as a dual boot, Ubuntu by default is loaded first. I changed it to make Vista the top selection. I wonder if that was the problem?

--Update: I just rebooted successfully using the GUI power button on the desktop. So apparently the problem lies within the Grub file. The question now would be, why is this breaking when I had windows set to be the default choice?

Post your menu.lst.

And no, changing the default wouldn't mess up the reboot like that.

# menu.lst - See: grub(8), info grub, update-grub(8)

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default		0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).

I made 1 change to the menu.lst file. Where it says default, it was set to 4. I re-edited so it said default = 0 which is how it initially was when I installed Linux.

Well, 4 would point to your Vista install. I don't see anything that would mess up the the reboot sequence.

Can you tell me what it says on screen right before it goes to the black screen?

[Nykc]

It acts like it wants to shut down normally. It closes any applications that are running and goes black as if it were shutting down. Then you can actually hear the hard disk speed up.

No messages, nothing.. Just a normal shutdown sequence. (well at least it appears to be.)

[MorphiusFaydal]

Try turning "ACPI Aware OS" odd in your BIOS.

[Nykc]

Ok time for a quick *Bump* I plugged my laptop back in and the problem is happening on linux again. The WiFi light stays on as if telling me in Range even though I am using the LAN connection right now. I don't know if this is the cause or not. It apparently is working when I am running off battery power but not when I am plugged in.

Morphius - I ran through the BIOS and pardon the noobish question but I didn't see that particular option.

I tried sudo reboot again and it doesn't reboot that way either.

I been heavily searching the Ubuntu forums and some people were suggesting adding acpi noacpi to the kernel line with little success.
