[SOLVED] New Kubuntu 9.10 Install, shutdown and reboot hangs???

[WildSioux]

Hello, I have been using LinuxMint 7 KDE CE for a while now and thought I would give Kubuntu a try. Actually, I am going to switch to strictly Kubuntu because there isn't a 2-3 month wait to get the updated version. As far as I can see you release a new version right along with Ubuntu.

Anyways, I have installed Kubuntu 9.10 on a separate partition to test out and copy all my stuff over from my Mint install before wiping that partition clean. Everything is going great! However, when I reboot or shutdown it just hangs.

I have found a few bug reports but these seem to be before 9.10 was released. I hope it was fixed and I am just missing something. Or maybe it wasn't fixed (dear god...why release in this state).

Any help is greatly appreciated. Thank you!

Re: New Kubuntu 9.10 Install, shutdown and reboot hangs

OK, I found that shutdown worked but a restart from KDE didn't. I did some searching and found it had something to do with ACPI (whatever that means)

I had to edit two files as per this post on ubuntu...Ubuntu Shutdown issues...post #7

Re: Ubuntu Shutdown issues
Hi, I had the same problem, and Saint Google helps me.
Here you have the solution that works in my PC, may be in yours too ...

1. Edit /etc/modules with "$ sudo gedit /etc/modules" and add a new line: "apm power_off=1"

2. Edit Grub menu with "$ sudo gedit /boot/grub/menu.lst" and look for the line with the kernel option you use normally (Ubuntu, kernel 2.6.20-15-generic in my own), at the end of this line add "acpi=off apm=power_off", without quotes of course.

3. Now you have to restart your PC in order that changes take effect.

Try it, good luck.

The /boot/grub/menu.lst is different in this version of ubuntu/kubuntu karmic. I found it is called /boot/grub/grub.cfg

I have Linux 2.6.31-14-generic (obviously with a fresh Karmic install). But what changed from jaunty to karmic? My computer isn't that old (6 year old Gateway desktop).

I am not sure what adding the lines "acpi=off" and "apm=power off" means. But does anyone know if there are any issues with adding these. Whatever the case, this solved the problem of it not restarting.

Re: New Kubuntu 9.10 Install, shutdown and reboot hangs

I was wrong about this fix. I am able to restart but now it hangs at shutdown. It shows the kubuntu splash after exiting kde, and goes to text. It makes a clicking noise like my hard drive and PSU is shutting off. But the screen and fans are all still running.

WTF This is disappointing Any ideas please?

Re: New Kubuntu 9.10 Install, shutdown and reboot hangs

I have found the fix (I hope) for this problem of being able to shutdown but not restart. I say "I hope" because I have shutdown and restart the computer a few times now and it seems to be working. Here is what I did after searching for a while with no fix or help except this.

http://www.linuxquestions.org/questi...untu-9-737358/

I was getting this same error (just a different number).

Restarting System

I found it had nothing to do with acpi settings in grub. Because when I added acpi=off or one of the other acpi lines...It allowed me to restart, but now it froze while shutting down.

That thread also had something in there about a "reboot" fix. This solved my problem...

"reboot=b"

I added that to /etc/default/grub
Changed this line from:

GRUB_CMDLINE_LINUX=""

to:

GRUB_CMDLINE_LINUX="reboot=b"

After making that change, I did this:

sudo grub-mkconfig -o /boot/grub/grub.cfg

I am now able to shutdown and restart without problems!!!
