How do I force xorg.conf to accept certain refresh rate?


What do I need to do to add into xorg.conf to use 75hz?

Under your monitor section, add this:

VertRefresh 75.0

HTH,

Code:
SubSection     "Display"
        Depth       24
        Modes      "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
can be changed to
Code:
SubSection     "Display"
        Depth       24
        Modes      "1280x1024_60" "1024x768_60" "800x600" "640x480"
EndSubSection

This is what I have now, but under KDE control center it still hanging on to 1024 x 768 @76hz, which I never ask for. Where did KDE get that from?

How do I force KDE to accept the resolution/refresh rate that are in xorg.conf?


SubSection "Display"
Depth 24
Modes "1280x960_75"
EndSubSection

you can try to add something like the following line in the end of Monitor section of xorg.conf:
Code:
ModeLine "1024x768_60"   65.0 1024 1048 1184 1344    768  771  777  806
you can use the another modeline calculator to create these values for you:
http://freshmeat.net/projects/amlc/

there is also an online calculator for this but i already forgot the site. you can try to search in google for it.

you can produce the modelines by running 'gtf <width> <height> <refreshrate> -x'.
Code:
gtf 1024 768 75 -x
