今天新裝了linux版本是thizlinux7.0我安裝的是xwindow當我啟動機器進入登陸名和密碼以後奇怪的事情發生了，
機器意外的黑屏，頓時不知所措，首先想到的是顯卡問題。經過檢查沒有問題。於是很自然的去差看了下
下面是我的一些命令
[root@localhost root]# ls
anaconda-ks.cfg etc install.log.syslog MyComputer

[root@localhost root]# cd /etc/X11

#
# 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" [已轉換] 57L, 1756C
這裡把 參數 5改成3
然後重啟
reboot
這個時候已經沒有了界面因為屏蔽了它，直接進入命令的文本情況下
[root@localhost etc]# redhat-config-xfree86
* ddcprobe returned bogus values:
ID: None
Name: None
HorizSync: None
VertSync: None
在這裡會彈出一個對話框，我們可以把分辯率弄成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
然後會出現很多設置情況
找到刷新頻率
將其更改為30。0?50。0
50。0?90。0
解析度改為1024＊768
然後reboot重啟
進入以後startx進入桌面就OK了
當然不同的硬體更改方法不一樣
對於linux支持的硬體也不一樣，所以修改的2時候現要想到自己的硬體能否支持
這個問題出現的原因是顯卡linux已經認出但是由於其它的原因使刷新頻率不正常導致黑屏，黑屏的事後還可能反覆的重啟。
