linux has a built in "firewall" in the kernel. commonly called
Netfilter and iptables. Basically, it controls what the kernel does
with network traffic. There are various ways to configure it. check
out shorewall

aptitude install shorewall

man shorewall

you might check out xresprobe. I'm not positive it does refresh rates,
but might help.

also, have you googled the monitor model number and name? there are
several websites that have specs for all kinds of monitors. the
manufacturers website may also have the information.

you have already been told several times how to reconfigure X.

dpkg-reconfigure xserver-xfree86

did this not work for you?

then its probably working.

it may be that there isn't enough RAM to run the installer. please
provide more specs on the machine in question. you may have to use woody installer and upgrade.

And don't take this personally, but as a piece of friendly
advice. There is a wealth of information available to you that you
should be looking into BEFORE you ask questions. the Debian website
has lots of documentation. Also there is a ton of information on your
machine already: man, info, apropos and plain old
/usr/share/doc... and don't forget the all powerful google. you can
search just debian mailing list archives by including
site:lists.debian.org in your search string.

the folks on here are eager to help if it appears you've helped
yourself first. please read:
