i845G集成的显卡装完驱动,分辨率仍只有640*480??

cheyo

我的系统是redhat 8.0
我的显卡是intel845G主板集成的显卡,去intel网站下载了845G显卡的驱动.
并安装.但安装后把"菜单"->"系统设置"->"显示" 的分辨率设成了800*600.
但仍只有640*480.请问如何把分辨率改为800*600?
我曾试着把/etc/X11/XF86Config文件中 Section "Screen"  段的分辨率改为单一的800*600,但也是没有效果.

以下是/etc/X11/XF86Config文件修改中的内容:


# File generated by anaconda.

Section "ServerLayout"
        Identifier     "Anaconda Configured"
        Screen      0  "Screen0" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice        "Mouse1" "SendCoreEvents"
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"

# The location of the RGB database.  Note, this is the name of the
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.

    RgbPath        "/usr/X11R6/lib/X11/rgb"

# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

    FontPath   "unix/:7100"

EndSection

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
#        Option        "Xleds"                "1 2 3"

# To disable the XKEYBOARD extension, uncomment XkbDisable.
#        Option        "XkbDisable"

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#        Option        "XkbModel"        "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#        Option        "XkbModel"        "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#        Option        "XkbLayout"        "de"
# or:
#        Option        "XkbLayout"        "de"
#        Option        "XkbVariant"        "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#        Option        "XkbOptions"        "ctrl:swapcaps"
        Option        "XkbRules"        "xfree86"
        Option        "XkbModel"        "pc105"

VertRefresh 50-160
这个值太高了.
改成50-85就行了.
