Nothing sophisticated but easier to debug certain tablet oddities. It shows a bar for each axis on the tablet (and the evdev axis) and prints that relative to the axis range. This makes it easy to check if we do hit the full range (especially for distance/pressure/tilt) and whether that matches with what the device gives us.

.SH DESCRIPTION
|
|
.PP
|
|
The
|
|
.B "libinput debug-tablet"
|
|
tool debugs the values of the various axes on a tablet. This is
|
|
an interactive tool. When executed, the tool will prompt the user to
|
|
interact with the tablet and display the current value on each available
|
|
axis.
|
|
.PP
|
|
This is a debugging tool only, its output may change at any time. Do not
|
|
rely on the output.

This tool usually needs to be run as root to have access to the
|
|
/dev/input/eventX nodes.
|
|
.SH OPTIONS
|
|
If a device node is given, this tool opens that device node. Otherwise, this
|
|
tool searches for the first node that looks like a tablet and uses that
|
|
node.
