| oh well, for arguments sake, suppose I do not know about monitor refresh

The major issues are:
a) X might crash, if probe is done within X.
b) values might be unreliable (same note as a)).
c) it isn't enough to do that via dpkg-reconfigure but we will need some
~   sort of init script to check the actual hardware configuration
~   increasing a lot complexity of the startup. Imagine a card that hangs
~   if probed.
d) you might have changed your video card and the monitor probe can fail
~   (since they are strictly dependend one to eachother) and therefor
~   get prompted for frequencies of a perfect working monitor... humm
~   "but i didn't change my monitor in years"..

You too?? it must be a quite common problem ;)

As i explained in the previous email, that is ONE way to do so and it is
the same as asked: reproducing the same environment as install time.

It is not required to deinstall a package or reinstall it to do a
configuration.

Also, dpkg-reconfigure xserver-xfree86 is already pre-seeded with proper
values. That means that if you are changing the video card, you only
need to change one answer and hit enter to all the others.

For the specific problem of the monitor frequencies, you have 3 levels
of input that goes from simple to advanced. With the former asking only
the size of the screen, to the latter asking manual input of freq.
range. The Medium one fits 99,99% of the users out there.
