my touchpad suddenly stopped working
I looked at libinput list-devices and it gives me this:

libinput list-devices  :heavy_check_mark:

It wouldnt have, but it appears some parts of it were removed/edited.

So now part of those comments are visible along with the arrow before your post.

Usually the idea is to not touch it at all … or remove it entirely.

The following should work for that command;

sudo libinput list-devices

but using sudo it says:

sudo libinput list-devices  :heavy_check_mark:

One thing to try:

sudo modprobe -r psmouse && sudo modprobe -a psmouse

This happens to me after a sleep cycle, typically just the first one following a reboot.

If the above command works, I’ll find the post where someone detailed a script to run on resume.

Thank You. unfortunately it didn’t work.
It happened suddenly.It was working and then it stopped… I had done a reboot, that 's right, but this event happened long after it.
What could it be? It has worked fine so far.
