Trackpoint stops working a few seconds after login

I have a Thinkpad T440p on the standard Linux kernel and SwayWM. The trackpoint stops working a few seconds after login. I can fix it temporarily by shutting the lid, putting the device into sleep, and waking it up again, but it stops working again after a few seconds. I tried reinstalling Arch to fix it, but that didn't seem to affect this behavior at all. I tried modprobe psmouse proto=bare and psmouse elantech_smbus=0. Neither of those options affected it either. I used to be able to modprobe to restart psmouse and bring back the trackpoint for a few seconds.

Re: Trackpoint stops working a few seconds after login

Few seconds sounds more like usb autosuspend than PS/2?

lsusb

Does the device still produce input in "sudo evtest" after it "stopped working"?

Re: Trackpoint stops working a few seconds after login

Try to check if the input device is disabled with xinput but I'm not sure it works with wayland

$ xinput list

Running lsusb before and after the trackpoint stops doesn't show any changes, and evtest does not detect any events.

Re: Trackpoint stops working a few seconds after login

Please avoid bloating the thread by pointless full-quotes.
Iff the device is on USB it won't disappear when it autosuspends, the idea was more to post the output of lsusb to see whether it's there at all.

Edit: reads like PS/2, though.
Please post your complete system journal for the boot after it failed:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Re: Trackpoint stops working a few seconds after login

I don't think it has that much to do with suspend because I don't need to suspend for the issue to occur. It happens a few seconds after boot up.

Re: Trackpoint stops working a few seconds after login

I don't either, it's just that the suspend probably indicates a mitigating effort and it exposes this condition.
See the other thread and post the output of modprobe.

I did have a suspicion yesterday that it could be related to tlp since I used tpacpi instead of tlp a year ago when I didn't have the issue. Anyway, here's the output:

Re: Trackpoint stops working a few seconds after login

Have you since disabled TLP
Otherwise try to set psmouse.synaptics_intertouch=1

Re: Trackpoint stops working a few seconds after login

Unfortunately neither disabling tlp or setting psmouse.synaptics_intertouch=1 worked.

Does "psmouse.proto=bare" still work?

Re: Trackpoint stops working a few seconds after login

No, psmouse.proto=bare doesn't work either. I forgot to mention it, but it was actually one of the first things I tried.

Re: Trackpoint stops working a few seconds after login

So, I tried setting psmouse.proto=bare again, but in the kernel command line instead of modprobe, and it's promising. This is the longest the trackpoint has worked for so far, but it has also broken the gestures and scrolling.

Re: Trackpoint stops working a few seconds after login

modprobe could be spoiled if the module is (likely) in the initramfs and you don't have the modprobe hook or didn't regenerate that.
How did you go about psmouse.synaptics_intertouch=1 itr?

Using the bare protocol doesn't support gestures and scrolling, so that's not much of a surprise.

Re: Trackpoint stops working a few seconds after login

I also put psmouse.synaptics_intertouch=1 in the kernel command line. psmouse.proto=bare is a very unhappy switch since I can't scroll by holding down the middle button and pulling the trackpoint anymore. In fact, the trackpoint gets disabled if I press any of the 3 buttons. I'd like to at least fix that. I don't need touchpad gestures, but I need my trackpoint features.

Re: Trackpoint stops working a few seconds after login

Using the bare protocol is more to figure whether the thing actually still works at all.

Did you try combinations of psmouse.elantech_smbus=0 and psmouse.synaptics_intertouch=0 ?
(check "systool -vm psmouse" to make sure they applied)

Re: Trackpoint stops working a few seconds after login

It looks like a combination of psmouse.proto=bare and psmouse.proto=imps does what I want. Proto=imps fixed the buttons disabling with the trackpoint. Now there's just one more problem being that when my palm accidentally touches the touchpad, the trackpoint gets disabled.
Edit: Nevermind, I have no idea why it's so unreliable but at least proto=imps gets it working somewhat. It looks like it may have overidden proto=bare because my touchpad is showing up in swaymsg as a synaptics touchpad instead of ps/2 mouse now.

Re: Trackpoint stops working a few seconds after login

You cannot combine those, but their order will dictate which onw applies.

So "psmouse.proto=imps" works?
Does "psmouse.proto=exps"?
Did you try "psmouse.elantech_smbus=0" (instead of any psmouse.proto)?
Does

Now there's just one more problem being that when my palm accidentally touches the touchpad, the trackpoint gets disabled.

Re: Trackpoint stops working a few seconds after login

psmouse.elantech_smbus=0 doesn't seem to do anything. Psmouse.proto=imps works, but with reliability issues, and I keep accidentally moving the touchpad. I haven't tried psmouse.proto=exps.
