系统开机自启动问题

小菜电脑在断电不正常关机之后
每次重新启动系统，就会默认自启动 以前断电之前运行的程序
不想让他开机自启动，在那里设置阿？
达人帮帮忙....

默认给自启动了3个console，2个VBOX，还有skype
一开机进桌面就弹自动弹出来了，烦不胜烦...
苦闷中

GNOME环境

~/.bash_profile 此文件内容如下
－－－－－－－－－－－－－－－－－－－－－－－－－－
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
unset USERNAME

~/.bashrc 内容如下
－－－－－－－－－－－－－－－－－－－－－－－－－
# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi
－－－－－－－－－－－－－－－－－－－－－－－－－
/etc/rc*.d此文件里S开头的文件看了，没看出个所以然来。。。。

贴出启动日志吧 ！

/var/log/cron 如下：
