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.

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.  :-\

..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.

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
