[wellylug] centos 5 dual head failed!

[Mian Lin]

finally found out it is nothing about with bios but the type of monitor
One monitor is LCD , another CRT, they both use VGA interfaces. The
video card has two interfaces, DVI and VGA. the CRT one connects to
DVI using adaptor, the LCD -> VGA. That works with dual head setting.
but if LCD connects to DVI using adaptor and CRT -> VGA , it just
doesnt work whatever I edit the xorg.conf.
I have no idea why.
Hopefully not making you sleepy. but I am ^_^
