Any error messages? Xorg has changed a lot from slackware 12.2 and 13.0. Have you tried to use xrandr for setting up dual head instead?

hi gapan,
thank you for your interest about my problem..
is the first time that I listen about xrandr and I don't know how it works.
Can you suggest me a link (other than man) where I can find any example how to do?

Here: http://www.thinkwiki.org/wiki/Xorg_RandR_1.2
and for a shorter one here: http://navetz.com/v/132/Simple-dual-mon ... untu-Linux

You should be able to do everything with a single command line and do it on the fly without using any xorg.conf

aaargh!.. my [old VGA] Matrox G450 DualHead is not supported by xrandr
seems to be very strange that I can't display a large desktop on two monitors whith a dual head board.
for now, I only can see the same desktop on every monitor, any idea?..
