no choice of refreshrate in kde display menu

hi!

i would like to lower the refreshrate for my tft (that reduces signal corruption caused by my kvm switch...), but i have only one refreshrate for each resolution in the menu. for example, i can only use 75Hz with 1280*1024, or only 85Hz with 1024*768.

the grafics adapter is a nvidia geforce f52 i think, and the monitor is a viewsonic tft.

in windows, it works with every refreshrate i choose.

changing the xorg.conf seems to have no effect, i changed the rate range, and also set it explicitely to 60Hz in the monitor section, nothing works. what can i do?

thanks

maybe the xorg manual could help, or info on the X.org website - i've never thought about this. it's very likely xorg automatically detects and sets this, and i don't know if you can change it at all...

... the manual says the same as the xorg.conf: configure the two variables (i think it was horizsync and vertrefresh) and go. but kde ignores the values i set there completely.

RE: no choice of refreshrate in kde display menu

Try to change the freq. by right clicking your desktop -> Configure Desktop -> Display. There should be field to change the frequency. Otherwise I'm clueless why KDE does not respect it.

that's what i've written in the very first post: in this menu i can only select one frequency per resolution. that does not at all comprehend the possibilities of the hardware. in windows for example i can select 60, 70 and 72 hz (when only the supported modes are shown) and in don't want linux at all to use 75 hz.
