<pre>I have Asus K55VM-SX086D laptop. The touchpad is ETPS/2 Elantech Touchpad.
Pointer movement was very fine when synaptics driver was in use. After
switching to libinput, I no more feel the same accuracy and control as it used
to be. I am not able to precisely point objects, I either overshoot or
undershoot them. I have already tried adjusting accel speed via xinput,
hysteresis patch, this patch:
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=1316655">https://bugzilla.redhat.com/show_bug.cgi?id=1316655</a>, but no success. Following
are the details:
