[fdo] Doubt in XOpenDisplay

[Karthik Ramamoorthy]

Hi,

   How can i use XOpenDisplay function to open the secondary
screen of my dual head card.

     When i use XOpenDisplay(":0.0") its opening the primary or
default screen the then when i try with  XOpenDisplay(":0.1") its
giving error unable to open the display.

    Can anybody tell me how to open the two screens in case of Dual
cards ie Dual Monitor System.

Thanks & Regards
Karthik
