今天新装了linux版本是thizlinux7.0我安装的是xwindow当我启动机器进入登陆名和密码以后奇怪的事情发生了，
机器意外的黑屏，顿时不知所措，首先想到的是显卡问题。经过检查没有问题。于是很自然的去差看了下
下面是我的一些命令
[root@localhost root]# ls

# inittab This file describes how the INIT process should set up
# the system in a certain run-level.
#
# Author: Miquel van Smoorenburg, <miquels@drinkel.nl.mugnet.org>
# Modified for RHS Linux by Marc Ewing and Donnie Barnes
#
# Default runlevel. The runlevels used by RHS 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:
# System initialization.
si::sysinit:/etc/rc.d/rc.sysinit
l0:0:wait:/etc/rc.d/rc 0
l1:1:wait:/etc/rc.d/rc 1
"inittab" [已转换] 57L, 1756C
这里把 参数 5改成3
然后重启
reboot
这个时候已经没有了界面因为屏蔽了它，直接进入命令的文本情况下
[root@localhost etc]# redhat-config-xfree86
* ddcprobe returned bogus values:
ID: None
Name: None
HorizSync: None
VertSync: None
在这里会弹出一个对话框，我们可以把分辩率弄成800x600[root@localhost root]# cd /etc/X11
[root@localhost X11]# ls
applnk menu starthere XF86Config.backup xkb
desktop-menus prefdm sysconfig XF86Config.bat Xmodmap
fs proxymngr twm XF86Config.det Xresources
gdm rstart X XftConfig.README-OBSOLETE xserver
lbxproxy serverconfig xdm xinit xsm
[root@localhost X11]# vi xf86.comfig
然后会出现很多设置情况
找到刷新频率
将其更改为30。0—50。0
50。0—90。0
分辨率改为1024＊768
然后reboot重启
进入以后startx进入桌面就OK了
当然不同的硬件更改方法不一样
对于linux支持的硬件也不一样，所以修改的2时候现要想到自己的硬件能否支持
这个问题出现的原因是显卡linux已经认出但是由于其它的原因使刷新频率不正常导致黑屏，黑屏的事后还可能反复的重启。
