KDE won't logout, reboot or shutdown

[cat2005]

Sometimes KDE won't logout, reboot or shutdown when I go to the proper menu.

How do I fix this?

Using KDE 4.8.5 on 64bit Ubuntu 12.04

When that happens have you tried to reboot or shutdown through a terminal, and did that produce the desired result?

Unfortunately I don't know much about terminal. I was in my non-root account. I tried the following in terminal but got the reply that I needed to be root.

shutdown -h now
reboot -h now

I assume my syntax is correct but like I said, I don't know that much about command line. I always manually reboot when this happens.

Just add sudo to the front of either command while in the Terminal window.

I.E.

sudo shutdown -h now
sudo reboot -h now

Although you really can replace the bottom one with Sudo shutdown -r now. Think it does the same thing.

reinstall the package menu-xdg or install it if it is not installed. this is the one that has the reboot shutdown options
