Hi all,

I am attaching here my xorg log file, output of xinerama api's and co-
ordinates of Root window.I could get damage report for rootwindow area
of 1024 x 768.

Why i couldn't get damage report for area of (1024 - 2048) * 762?

(Second part of root window which is being virtualy enabled by dummy
driver to memic the second video card display).

What is the wrong i am doing here? Is there anything i am missing?

This is the way i created damage report over root window.

rootWin = RootWindow(g_Display,screen_num);
xdamage = XDamageCreate(display, rootWin, XDamageReportRawRectangles);
if(event.type == event_base + XDamageNotify)
{
dev = (XDamageNotifyEvent *) &event;
x = dev->area.x;
y = dev->area.y;
w = (dev->area.width);
h = (dev->area.height);
UpdateRect.left = x;
UpdateRect.top = y;
UpdateRect.right = x + w;
UpdateRect.bottom = y + h;

}

Co-ordinates of root window,

left 0
top 0
width 2048
Height 768
