O Ubuntu fica preso na tela de desligamento [fechado]

Acabei de instalar o e4rat (um programa para tornar seu tempo de inicialização mais rápido) e configurá-lo. Agora, o tempo de inicialização é muito mais rápido, mas quando eu quero desligar ou reiniciar, minha máquina fica presa na tela de desligamento.

O que posso fazer para evitar isso?

Não estou usando o Ubuntu no Virtualbox. O Ubuntu (13.04) é o meu verdadeiro PC-System instalado no disco rígido. Mas eu instalei o Virtualbox do Centro de Software no meu Ubuntu 13.04. Aqui estão as últimas linhas de /var/log/kern.log

Veja como consertei:

Primeiro, os bugs superiores não eram os únicos. Eu também tive um uso de memória extremamente alto, os gráficos não funcionaram direito, tudo correu extremamente lento, meu uso da CPU foi sempre de cerca de 90% (eu tenho um AMD-FX6300 Six Core !!!), eu não conseguia montar dispositivos e o som não funcionou. Então, aqui está o que eu fiz para resolver isso. Acabei de instalar manualmente o novo kernel 3.9 assim: 

wget http://goo.gl/g1XHX
chmod +x g1XHX
sudo sh g1XHX

g1XHX: 

#!/bin/sh
echo "$(tput setaf 3)--- Kernel 3.9.4 - lffl will be installed in an 'uname -i' system---$(tput sgr0)"
echo ""
sleep 2
read -p "Press Enter to continue, or abort by pressing CTRL+C" nothing
echo ""
echo ""

#System architecture
arch='uname -m'

if  [ $arch = i686 ] || [ $arch = i386 ]; then
    mkdir -p $HOME/kernel-i386 
    cd $HOME/kernel-i386
    wget -c $link1
    wget -c $link2
    wget -c $link3
    sudo dpkg -i *.deb  
    sudo rm -rf $HOME/kernel-i386
elif [ $arch = "x86_64" ]; then
    mkdir -p $HOME/kernel-amd64
    cd $HOME/kernel-amd64
    wget -c $link1
    wget -c $url1
    wget -c $url2
    sudo dpkg -i *.deb  
    sudo rm -rf $HOME/kernel-amd64
else
    echo "Unsupported Architecture"
fi

Então eu reiniciei e tudo funcionou bem!

Tenho XP em uma partição e o Windows 7 em outra. Como instalo o Ubuntu em uma partição separada? Novo para isso, quer instalar o Cairo Desktop [duplicado]
