My monitor is SAMSUNG samtron 45Bn,
Now my problem is after every reboot i have to configure xwindow.
which i does normally like /usr/sbin/setup-> configure the xwindow
configuration -> vcard as above -> monitor-> custom->

I also tried by xf86config command line xwindow config tool but did't
work out,
