xvidtune无法消除屏幕闪烁？

cwflying

Redhat AS4,17寸显示器，屏幕一直闪烁，用system-config-display修改了多次，屏幕还是闪烁不止，按照网上介绍的做法，用xvidtune命令，在xorg.conf里增加了一行（xorg.conf里红色字体标识）:
Modeline     "1024x768"     94.50   1024 1076 1172 1372    768  773  776  808 +hsync +vsync
系统重启后屏幕还是闪烁。

# 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"
# Or if you just want both to be control, use:
#       Option  "XkbOptions"    "ctrl:nocaps"

权老实

用xvidtune 不断试验,按TEST OK后,按SHOEW 查.参数
