+.SH SCROLL PIXEL DISTANCE
+The X server does not support per-pixel scrolling but it does support
+smooth scrolling. All scroll events however are based around a logical
+unit of scrolling (traditionally corresponding to a wheel click).
+It is thus not possible to scroll by 10 pixels, but it is possible for a
+driver to scroll by 1/10th of a logical wheel click.
+.PP
+libinput provides scroll data in pixels. The \fBScrollPixelDistance\fR
+option defines the amount of movement equivalent to one wheel click. For
+example, a value of 50 means the user has to move a finger by 50 pixels to
+generate one logical click event and each pixel is 1/50th of a wheel click.
+.SH BUGS
+This driver does not work with \fBOption \*qDevice\*q\fR set to an event
+node in \fI/dev/input/by-id\fR and \fI/dev/input/by-path\fR. This can be
+usually be worked by using \fBSection \*qInputClass\*q\fR with an
