Re: Xorg @ 1440x900 @ 75 Hert

Do you really need 75 HZ ? If it is lcd then there is no flicker anyway. Let it live at 60 Hz

To specify any special setting search the internet for an appropriate modeline. then add it in section monitor and refer to it from section screen

Yes I need

I've searched but the only working modeline is that in my xorg.conf....

Isn't someone that use 1440x900 @ 75 hz?

I've also tried to replace

HorizSync    30.0 - 80.0 # Warning: This may fry old Monitors
    VertRefresh  60.0 - 70.0 # Very conservative. May flicker.

Whith:

HorizSync    30.0 - 83.0 # Warning: This may fry old Monitors
    VertRefresh  55.0 - 75.0 # Very conservative. May flicker.

And KDE makes me to choose only 50-54-55 Hz

Please Help!

Re: Xorg @ 1440x900 @ 75 Hert

The numbers you see (50, 52, and so on) are not actual refresh rates, they're just identifiers nvidia driver uses.  See this (from nvidia driver readme):

Option "DynamicTwinView" "boolean"

    Enable or disable support for dynamically configuring TwinView on this X screen. When DynamicTwinView is enabled (the default), the refresh rate of a mode (reported through XF86VidMode or XRandR) does not correctly report the refresh rate, but instead is a unique number such that each MetaMode has a different value. This is to guarantee that MetaModes can be uniquely identified by XRandR.

    When DynamicTwinView is disabled, the refresh rate reported through XRandR will be accurate, but NV-CONTROL clients such as nvidia-settings will not be able to dynamically manipulate the X screen's MetaModes. TwinView can still be configured from the X config file when DynamicTwinView is disabled.

    Default: DynamicTwinView is enabled.

So in order to see the actual refresh rates you need to add something like:

Option "DynamicTwinView" "false"

to the device section of xorg.conf (assuming that you're not using a TwinView setup).

If you need to specify the refresh rate in xorg.conf explicitly try using something like this in xorg.conf:

    SubSection "Display"
        Depth     24
        Modes "1440x900_75"
    EndSubSection

Re: Xorg @ 1440x900 @ 75 Hert

What is seen in the Modes is the name of the modeline. You need to have one with this name
