Cannot shutdown or restart Ubuntu 10.04

Asked by Akintayo

Binary package hint: gdm

I installed Ubuntu 10.04 LTS about 1-2 weeks ago, after a 5 day old install decided it no longer wanted to start X. I installed 10.04 LTS from scratch, wiping out the prior install.

Now, I have noticed that I cannot shutdown or restart my install. Instead of shutting down or restarting I get logged out. From the login dialog, I can select shutdown and restart but again nothing happens. The only substantive change I can recall making since the last reboot, has been to change from LTS to Normal releases in synaptic.

I've attached the log of changes made from synaptic. I don't see any packages that are likely to stop me shutting down my computer.

this is the only thing i can think to try. first lets backup grub:

open a terminal and type:
sudo cp /etc/default/grub /etc/default/grubbak

now some people report success by doing this:

open a terminal and type
"sudo gedit /etc/default/grub"
you should see something like this:
----------------------------------------
If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT="10"
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console
-----------------------------------------
where it says "GRUB_CMDLINE_LINUX="" is where you will add acpi=force. it should look exactly like this:
GRUB_CMDLINE_LINUX="acpi=force"

however some others report success using this instead. some people report bugs when adding to options to GRUB_CMDLINE_LINUX (shown above). try editing your /etc/default/grub and moving the acpi option to the "DEFAULT" line as seen below.:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

save your file and get in your terminal again and type:
"sudo update-grub"

restart your computer

I made the change and turned off the power. After starting up again, I could shutdown and reboot.
