+Subject: [PATCH xf86-input-libinput] Only init abs axes if we don't have
+ acceleration
+
+A lot of devices (mainly MS input devices) have abs axes on top of the
+relative axes. Those axes are usually mute but with the current code we set up
+absolute axes for those devices. Relative events are then scaled by the server
+which makes the device appear slow.
+
+As an immediate fix always prefer relative axes and only set up absolute axes
+if the device has a calibration matrix but no pointer acceleration.
+This may mess up other devices where the relative axes are dead, we'll deal
+with this when it comes.
