I am trying to track down a CloseDownExtension process and stuck at
glxscreen.c.
I need to know where the screenInfo is initialized ? I completely lost to
find it.

And I modified something at void __glXResetScreens(void) become like this:
----------------------------------------------------------------------------------------------------------------------------------

void __glXResetScreens(void)
{
  int i;
  int j;

  j = screenInfo.numScreens;

  for (i = 0; i < j; i++)
      if (__glXActiveScreens[i])
          __glXActiveScreens[i]->destroy(__glXActiveScreens[i]);

    xfree(__glXActiveScreens);
    xfree(__glXHyperpipeFuncs);
    xfree(__glXSwapBarrierFuncs);
    __glXNumHyperpipeFuncs = 0;
    __glXNumSwapBarrierFuncs = 0;
    __glXHyperpipeFuncs = NULL;
    __glXSwapBarrierFuncs = NULL;
    __glXActiveScreens = NULL;
}
----------------------------------------------------------------------------------------------------------------------------------

My goal was to see the value of screenInfo.numScreens on gdb. But it always
reset the mechine everytime I press Ctrl+Alt+BackSpace and left me nothing.

I use only one mechine so I redirect the output to a file with ">& file".
