Hi,

I have a problem with my computer occasionally restarting on shutdown.

Sometimes when i shutdown it reboots.

on both host and guest running CentOS 6.3 with KVM/Qemu virtualization, I have the following scenarios:

"virsh shutdown kvm1" did not shutdown at all. virsh lists guest as running. "service libvirt-guests stop" did not shutdown in 280 seconds (shutdown_timeout=300. on_shutdown=shutdown) "shutdown now" from within guest, guest becomes unreachable.

Hi, I updated from Fedora11 to Fedora12. Now I would like reboot / Shutdown the system but it does not reboot. Whenever I click Reboot or shutdown, it comes back to login screen without booting.

Any help is highly appreciated before I press power off switch. Also, ABRT service is not running is flashing at corner.

Thanks for your time and help.

I recently installed ubuntu 12.04 on my laptop, when I down loaded the updates a few days later I find it no longer does a complete shutdown, The screen comes up with the prompt for password, the settings icon shows a shutdown symbol , but it is obviously not. I can force shutdown by holding the power button.

I am using Ubuntu 11.10 and I am unable to shutdown via shutdown option. If I issue a shutdown the system goes back to the login prompt. I can shutdown the system only via terminal using sudo shutdown -h now. Let me know how to resolve this issue.

Some are fairly obvious. Specifically, I am referring to:

-h halt or power off after shutdown -H halt after shutdown (implies -h) -P power off after shutdown (implies -h)

Isn't halting or powering off kind of expected when you're shutting down?

I have ubuntu 11.10 64bit, everything worked fine but after i uninstalled the airtime dj app i can't restart or shutdown my pc !! The only way to reach at the screen showing that system is going to shutdown is via terminal but it stucks and never shuts down ! I can't even restart it ! I can suspend my pc fine but can't shutdown or restart it.

I've been using Wake on Lan for some time. Recently, I made some changes to grub and about that same time I could no longer shut down my machine from Ubuntu.
