I think that the values are stored at

/etc/X11/xorg.conf

Here is what I see there pertaining to the refresh rate:


Section "Monitor"
    Identifier    "Generic Monitor"
    Option        "DPMS"
    HorizSync    28-64
    VertRefresh    43-60
EndSection

I tried pumping up the refresh rates by changing the values as recommended
here:

  Section "Monitor"
    Identifier "KVM Host Monitor"
    HorizSync 30-70
    VertRefresh 50-75
    # 'man xorg.conf' says you can set the pixel clock in KHz.
    # This is an UNTESTED example for 10-110 MHz clock:
    #Option "MinClock" "10000"
    #Option "MaxClock" "110000"
  EndSection
but no joy.  Still the same flicker and I am still not seeing any options
other than zero when I click on

System > Preferences > Screen resolution

Any help welcome!

thx in advance.
