No one know?

I want to change the refresh rate from default value(maybe 60Hz) to 75Hz.

Because my display device is CRT, not LCD.

[jls]

I think u need to install xorg

You can't change refresh rate in Xvesa, because it was designed only for 60 Hz.
You have to install Xorg and set in xorg.conf correct refresh rate range.

for example
Section "Monitor"
Identifier "NEC MultiSync FE2111SB"
VendorName "NEC"
ModelName "FE2111SB"
HorizSync 30 - 80
VertRefresh 50 - 70
Option "dpms"
EndSection

but I don't know what to do next, because I was always using KDE to change refresh rate. Maybe xrandr will help.

Using Xfce4 you can change it in the Settings menu.

Click Settings on the desktop or select in the Applications menu, than choose Display.

..still not exactly the same topic, but anyway  

You could try something similar to this:

Code: [Select]

Section "Screen"
Identifier "Screen0"
Device     "Card0"
Monitor    "Monitor0"
SubSection "Display"
Viewport   0 0
Depth     24
Modes     "1280x800" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
..adapted for your particular situation/xorg.conf of course.

[Chixiran]

i create xorg.conf file in /etc/X11. and input the info you give to me. but it do not work ,when reboot, xorg.conf is delete automatically.

OK, so this means you're running Xorg "confless", have a look at the Xorg info file and follow the instructions to generate an xorg.conf and see if that works

[Chixiran]
