The wacom driver Debian has does not build against current X server.

Maybe there is something newer somewhere..

The strip that is not reachable is quite large preventing me from
pointing at the first letter in urxvt.

The cursor is actually above the letter but not visible which is not
tremendously useful.

Of course, I could possibly prevent this by inserting some 32px
invisible stripe between the screens and hope that the screen
switching code only switches once the cursor pixmap reaches the other
screen. This is however quite difficult to do because the convenience
--right-of does not insert the stripe.
