Touchpad not recognized

My touchpad stopped working. I get this message right after listing the devices from libinput:

I’d suggest trying another kernel, if you haven’t already. I have (had) issues with my Lenovo trackpads with various kernel series/revisions. It seems this also affects other brands.

Ones to try: linux66 (LTS), linux613, linux614 (both HWE) — I recommend keeping at least one other kernel on your system other than the one you are actually using.

There is, of course, also a possibility of a hardware fault.

I was using 6.12 LTS and tried 6.14… none works… :confused:

Do you still have the .ISO you installed from? If so, I guess that’s the next thing to try (as, presumably, it was working OK with that).

There is a command I sometimes need to use following a sleep/wake cycle (only the first one following a fresh boot):

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

… which might work with your setup.

In my case, the trackpad is unresponsive on the first “wake” and the machine won’t go back to sleep until I issue the above.

N.B. I also have a habit of keeping a USB mouse or trackpad in my backpack, in case of issues.
