You can probably make an xorg.conf file to get around this. I have had
to do this for a few machines with old monitors that don't provide information
as expected through EDID.

For F12 you'll probably add a mode line. In earlier versions of Fedora I
used to get mode lines for standard sizes (at 60Hz I think), but with F12
that isn't the case.

Making modelines is a bit risky as you can drive your monitor or video card
out of spec which might damage it. If you know it worked at 1024x768 60Hz
then you should be able to use that when making a new mode line definition.
