Ubuntu doesn't close properly
Hello everyone.
I installed Ubuntu 8.10, and it works as it should be - except for one thing. The shutter is not properly. When I put Ubuntu to switch off, then go down the line as it should, but when the hard drive is off and the computer is going to turn off completely, so it stays lit. It shuts off only when I press any key on the keyboard, and it annoys me. However, it is not always to do it, but it is only rarely that it turns off completely. I can solve the problem temporarily by taking out the battery and plugging it back until the problem occurs again a little while after. My laptop is an HP dv6645eo. What can the problem is and how do I remedy this? |
Linux - Hardware - ubuntu
Hi,
check with the hardware compatibility. Or check the updates are installed correctly. |
Boot Ubuntu to recovery mode. From recovery mode, choose "drop to root shell" from the menu that comes up. Then run:
Code:
shutdown -h now 1. Back up your grub menu.lst: Code:
sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.bak |
Now I believe that it is an ACPI problem. I have stopped Powernowd, because otherwise the CPU running at paltry 800mhz.
Could it have anything to do with it? I'm not sure it with GRUB list, think of if the computer can not start up, what do I do? |
Can you make a screenshot of the outcome, so I can see exactly how I should do?

Adding acpi=force to the kernel line in grub's menu.lst would not prevent the system from starting up. If you first back up menu.lst before editing it like I showed in my last post, you can always restore the original menu.lst if something goes wrong. Suppose you messed up menu.lst while editing it so that Ubuntu would not boot. To restore the original menu.lst, you can boot from the Ubuntu live CD, mount your Ubuntu partition, and replace the backed up menu.lst. For example, suppose Ubuntu is on /dev/sda2. You would do this from the Ubuntu live CD: Code:
sudo mount /dev/sda2 /mnt If you don't know what partition Ubuntu is on look at /etc/fstab. The partition that has the mount point as / (for root) is your Ubuntu root partition. I always back up any configuration file first before editing it for this reason. |

title Ubuntu 8.10, kernel 2.6.27-7-generic You only need to add acpi=force to the first entry in grub for booting Ubuntu. Don't worry about the entries below that for older kernels you may have. |
Now, I have again made the command "shutdown-h now" in recovery mode, and then it was off the disk, which said:
Will now halt: Could't not iterate IDE / ATA devices. (there was also something else but can not remember exactly what was written, but it had something to do with the HDD) But acpi=force works, the only one who would have been nice to boot graphics still appear, and it does not. Is there a way to turn it on? |
When I disabled Powernowd that was just the system faster. It did not resolve my problem.
Now I would like to have restored GRUB from the .bak file, but I can not doubleclick on the .bak file. How I restore the GRUB list without making use of Live-CD? |

If you backed up your menu.lst like this: Code:
sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.bak Code:
sudo cp -i /boot/grub/menu.lst.bak /boot/grub/menu.lst The "-i" switch is optional. It is a good safety feature because it asks you to confirm the overwrite, so you don't accidentally overwrite the wrong file. This is unlikely in this case, but in other cases many files have similar names, so a typo could accidentally overwrite the wrong file. |
Thanks a lot! My computer works properly now. :)

I thought to completely disable ACPI from, because this is what was the problem.
http://ubuntuforums.org/showthread.php?t=89491 The top two services had I intend to turn off. Will it work better? |
The problem now is back.
When I shut down Ubuntu, it's not always that there are ACPI Exiting. But when it does it come Power Down message not before I press any key. What can the problem is due? Dansk » Engelsk Oversæt |
