CentOS - Jul 2020 - Generating X configuration files

I'm trying to make my computer work with a Fedora 32 live DVD.
Video issues make it either crap out or only give me 640x480.
Grrrr.
Centos 7 is running just fine.

I think I could make it go by booting to
runlevel 3 and running startx manually.
For that to work, I think I need to pass
startx the right configuration file.

To me, 'tain't obvious what to put in that file.
Is there a way to get Centos 7 to
generate a configuaration file for me?

Note: I have discovered xrandr --verbose,
but do not know what to do with the information.
Is there a complete example file somewhere?

Using xrandr from F32 does not seem to work.
I either get told can't do that or that just does not happen.
