790GX设置刷新率之后黑屏

[greegree]

通过硬盘安装ubuntu 9.04之后首次进入系统能正常识别到显示器的分辨率为1440x900,但是刷新率为60Hz
在display中刷新率有75Hz选项,点击确认之后显示器黑屏.

按Ctrl+Alt+F1之后从tty登录进去查看/etc/X11/xorg.conf,内容如下:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

Section "Screen"

Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

发现没有75Hz的样子,使用sudo dpkg-reconfigure -phigh xserver-xorg 之后生成了一个带有日期的xorg.conf,但是两个文件的内容一样.
重启机子后再session上依然能看见登录窗口,但是登录之后又是黑屏.

在登录的session选择gnome的一个默认session正常,刷新率依然是60Hz,但是没有发现有配置文件被当前日期改写.

从Windows下之前安装的menu.lst中的liveCD选项进去还是黑屏.

不知道怎么回事.

目前的这个ubuntu 9.04 使用gnome默认的session可以使用,虽然不影响到正常的使用,但是总有疑问.

没有开swap,因为物理内存足够大,跟790GX内置的ATI HD3300共享后还剩余3327MB

遇到了差不多的问题，我是把分辨率调低了。然后登录窗口ok，登录进去后漆黑。

CRT还是LCD，如果是液晶，60Hz就行了，高了没用，有时还有反作用。

再顶起来

是液晶.但是不知道在Display中修改了75Hz之后改动了哪个文件,导致不行了.搜索也搜不出来.真是奇怪了.

添加红字部分看看

折腾这个问题太麻烦,今天早上从liveCD又重装了一遍,反正重装也用不了15分钟.

那也不用重装的,删了xorg.conf就可以了
