hiding X cursor

[Flavio Alberto Lopes Soares <flaviothunder terra com br>]

Hello all,
I'm developing an embedded application using GTK for run in an
industrial x86 PC104 computer with Linux (kernel 2.6.11.12), XFree86
version 4.5.99.8, GTK+ version is 2.6.4.
In my develop machine (I'm using Debian Sarge with default GTK+ runtime
& devel libs) I coded to hide the X cursor using the following code :

int
hide_cursor(gpointer user_data)
{

#ifdef HIDE_CURSOR
static unsigned char cursor1_bits[] = {
   0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00,
   0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00,
   0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}; 
static unsigned char cursor1mask_bits[] = {
   0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00,
   0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00,
   0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00};
  GdkCursor *cursor;
  GdkPixmap *source, *mask;
  GdkColor fg = { 0, 0, 0, 0 }; /* Transparent */
  GdkColor bg = { 0, 0, 0, 0 }; /* Transparent */

  gtk_widget_realize(GTK_WIDGET(user_data));
  source = gdk_bitmap_create_from_data(NULL, cursor1_bits,
cursor1_width, cursor1_height);
  mask = gdk_bitmap_create_from_data(NULL, cursor1mask_bits,
cursor1_width, cursor1_height);
  cursor = gdk_cursor_new_from_pixmap(source, mask, &fg, &bg, 8, 8);
  gdk_pixmap_unref(source);
  gdk_pixmap_unref(mask);   
  gdk_window_set_cursor(GTK_WIDGET(user_data)->window, cursor);
#endif

  return 0;
}

this code is from GDK Reference Manual, running in my develop machine
runs OK, the cursor disappears, but when I runs in my target board I see
the X cursor in screen, it not disappears, I run my program in target
board using :

xinit /usr/local/bin/maqface

but if I run using the same way in my develop machine the cursor
normally disappears.

What can be the problem ?

Thanks for any help
