如何解決centos虛擬機器無法啟動？

用VMware虛擬機器建立的一個centos桌面版系統。系統啟動時出現問題，啟動certmonger之後，介面卡住，無法進入圖形介面，如圖：

解決方法：

首先，Ctrl Alt F2進入命令列介面，用root用戶登錄，查看/etc/X11/xorg.conf檔案是否存在，如果存在，執行命令：

mv /etc/X11/xorg.conf /etc/X11/old_xorg.conf

重啟系統，看是否正常。

然後Ctrl Alt F2進入命令列介面，用root用戶登錄，修改檔案/etc/inittab

vim/etc/inittab

# inittab is only used by upstart for the default runlevel.
# ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
# System initialization is started by /etc/init/rcS.conf
# Individual runlevels are started by /etc/init/rc.conf
# Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf
# Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,
# with configuration in /etc/sysconfig/init.
# For information on how to write upstart event handlers, or how
# upstart works, see init(5), init(8), and initctl(8).     
# Default runlevel. The runlevels used are:
#   0 - halt (Do NOT set initdefault to this)
#   1 - Single user mode
#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
#   3 - Full multiuser mode
#   4 - unused
#   5 - X11
#   6 - reboot (Do NOT set initdefault to this)
#
id:5:initdefault:

將最後一行id:5:initdefault:修改為id:3:initdefault:則開機預設進入命令列介面。

重啟進入命令列之後，執行startx，則可進系統圖形介面了！
