Black Screen while using /dev/fb1

[umang gupta]

Helllo All ,

I have enabled 2nd frame buffer nodes in kernel . so that I have /dev/fb0
and /dev/fb1 devices .  Usually I start my X on fb0 [by default ] .
Now I wanted to move X display on fb1 .

I created a 22-xorg-fb1.conf  that contains as in :

*****
Section "Monitor"
    Identifier     "Monitor0"
    Option         "Enable" "true"
    DisplaySize     800 480
EndSection


Section "Screen"
    Identifier  "Screen1"
    Device      "fb1"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection "Display"
        Depth          24
        Modes          "800x480_60.00"
        EndSubSection

EndSection

Section "Device"
    Identifier  "fb1"
    Driver      "fbdev"
    Screen      0
    Option      "fbdev" "/dev/fb1"
EndSection

#Section "Screen"
 #   Identifier  "Screen0"
  #  Device      "fb0"
#EndSection

Section "ServerLayout"
        Identifier     "DualSreen"
        Screen      0  "Screen1" 25 25
EndSection
*********************

  I placed this conf file at /etc/X11/xorg.conf.d  .
Then restarted at X ...

But I am getting a black screen only ..

Any suggestions ??
