Kubuntu 9.10 Shutdown

[promike]

Hello,
I need some help.
I don't know what is the reason for this, but sometimes my computer doesn't want to turn off itself. Just blinking my power indicator. Sometimes does the shutdown procedure correctly, but sometimes i can read in a konsole message the "power off" or similar text (maybe power down, or i don't know now).
This error is a very unkidly thing, because i can't leave my room, until my computer shut down.

Check Error logs.
it might be a DBUS/HAL Issue..
Otherwise do the following in the Terminal: "su -c halt"

Hope that cures it for you =)
