在xorg.conf中的下列代码部分：
引用:Section "Monitor"
Identifier "Monitor0"
Option "DPMS" "true"
# HorizSync 28.0 - 78.0 # Warning: This may fry very old Monitors
HorizSync 28.0 - 96.0 # Warning: This may fry old Monitors
VertRefresh 50.0 - 85.0 # Very conservative. May flicker.
# VertRefresh 50.0 - 62.0 # Extreme conservative. Will flicke
将其中的VertRefresh数值调到85,重新启动后就可以了
哈哈原来这里的设置也是相当简单的咯
