<h1>Workaround for broken TrackPoint</h1>
<small><time>2022-12-05</time></small>
<p>
Sometimes, seemingly at random after clicking the dedicated left click
or right click buttons, the buttons and trackpoint on my Lenovo
Thinkpad T14s stops working. Instead of clicking, the three mouse
buttons just makes the pointer move a bit and the trackpoint makes the
pointer move in a random direction and seems to issue clicks.
</p>
<p>
When this happens, the kernel buffer is spammed with "<code>psmouse
serio1: elantech: discarding packet</code>". Searching the interwebs,
I found that more people seem to be experiencing similar weirdness with
the elantech trackpoint driver.
</p>
<p>
Rebooting the computer works, but it's annoying. Removing and re-adding
the misbehaving kernel module resolves the issue too fortunately. I
put the following in <code>~/bin/fixmouse</code>:
<pre><code>#!/bin/sh
doas rmmod psmouse
doas modprobe psmouse
</pre></code>
So now I can run <code>fixmouse</code> whenever the driver stops
working.
