Thanks. This patch seems work when restricting the cursor to a single
screen. With this patch the tablet is mapped to the whole screen.
However, if the cursor is free to move between screens the cursor
still jumps from the middle of the left screen to the middle of the
right screen (skipping the right side of the left screen and the left
side of the right screen).

when I start to recompile the gtk/gdk libraries...
