Have you tried running
Xorg -configure
as root, which will write xorg.conf.new into the current directory.
That should at least tell you what's being seen by the X server.

If what you posted is exactly that, then it doesn't look very hopeful.


Yes the the info posted is exactly same and this info belongs to 2.6.32 kernel.
The situation almost concludes that with 2.6.32 kernel is does not support HDMI and CRT configurations

However,  to understand how multiple monitor works installed a fresh copy of debian 7 (7.8) which uses 3.2.0-4-486 kernel version.
After installing, we noticed that the behavior is still same as debian 6 (2.6.32) . We see that connected display works.

Although, Xorg.conf has some information on Screen 0 : Card 0 and Screen 1 : card 1

Section "Screen"

With this XORG is there some possibility that i can individually control my connected interface. Am i missing some more configurations??
