[SOLVED] Forcing manual refresh rate?

How do I set the refresh rate manually and force X.org 1.6.x to keep it that way? Every time I turn off my computer and turn it back on, the refresh rate defaults to 75.0 Hz, which makes part of the screen sink into the monitor (a tiny bit, but still annoying). 59.9 Hz is a fine refresh rate for the monitor.

I am using KDEMod 4.2.4, X.org 1.6.1.901, and a Diamond Stealth Sxx video card (don't know exact model #).

Re: [SOLVED] Forcing manual refresh rate?

From my xorg.conf

Section "Monitor"
    Identifier          "Monitor0"
    VendorName          "Monitor Vendor"
    ModelName           "Monitor Model"
    HorizSync           28 - 51
    VertRefresh         43 - 60
EndSection

You should find the ones related to your monitor in your manual.

Re: [SOLVED] Forcing manual refresh rate?

Xorg conf now:

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 - 75.0 # Very conservative. May flicker.
    VertRefresh  50.0 - 60.0 # Extreme conservative. Will flicker. TFT default.
EndSection

If I put the vendor and model, the monitor section would be this:

Section "Monitor"
    Identifier "Monitor0"
    VendorName          "Acerr"
    ModelName           "X191W"
        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 - 75.0 # Very conservative. May flicker.
    VertRefresh  50.0 - 60.0 # Extreme conservative. Will flicker. TFT default.
EndSection

The screen displays fine now, it's just that KDEMod keeps thinking the refresh rate is  75 for some reason.

If it bothers you, you can always try the modeline approach.

Re: [SOLVED] Forcing manual refresh rate?

Bump!

Is there a way to switch refresh rate between 60 Hz (ac power) and 40 Hz (when on battery) smoothly? Lenovo software does it on Windoze to save battery, so I'd like to try it.
