Xorg default refresh rate for different resolutions
 

At one point Xorg changed behavior of modelines, I think it was Xorg 7.3. I want to set 60hz as the default for various lower resolutions like 640x480 800x600 and 1024x768. By default, I mean what it changes to when you simply run xrandr -s XxY without -r, they are also the first on the list when simply running xrandr. Before, I could do this by setting modelines for each resolution and specifying only those modes in the Screen section. Now it doesn't work. The modes show up, but the highest possible refresh rate is now always the default for each resolution. How could I do what I seek with this newer Xorg?

could you post the sections for your Monitor and screen so we can see what you have pls?

also what distro are you on and do you use KDE gnome or what window manager pls?

Distro is Fedora 8, using Gnome or Xfce, but honestly I don't think that matters.

The xorg sections are:

honestly if you used kde you could use kde control center that can have its values for screen refresh rates written to xorg.

2) you might try this force

ignore the values altho they mention one way of generating modelines xvidtune is another way.

I have tried all this already. The modes don't get rejected, they just don't get put at the front. Maybe new Xorg is hard coded this way. Also, manually changing rates is not going to work for my intended purpose because the targets run fullscreen. Switch out of full to change, switch back, they go back to the first refresh rate. They must be the default for a res in xorg. Thanks though.

If I set my Modes like this:
I have X running 1024x768 at 85Hz refresh rate. This may be specific to the nvidia driver so YMMV if you're using another driver.

Oh yes, it's very likely driver related. I'm running the regular "radeon" driver, which apparently sucks just like ati as a whole.
