[SOLVED] Touchpad suddenly stops working

This is the second time this has happened on the system, after a completely fresh install the touchpad works fine, but after awhile for some reason it just stops working.

If it helps, the touchpad light is on when it appears disabled, making me think I somehow accidentally switched it off via the keyboard, despite there not being any icon on the F keys indicating such a thing exists.

The system gives the following output for the touchpad's settings when I use

xinput list-props 11

Device 'SynPS/2 Synaptics TouchPad':

Is there a setting here that is causing all the issues? Sometimes rfkill kills my wifi via softblocking, I'm hoping it's something similar and thus easily fixable.

EDIT: I unblocked a hardblocked device listed with rfkill, my touchpad immediately started working again. Not sure if this was a giant coincidence as I thought rfkill only dealt with wireless devices.

Re: [SOLVED] Touchpad suddenly stops working

What desktop environment (if any) are you on? Although perhaps too obvious a suggestion and if you are indeed using a DE, have you tried the settings GUI? Is f86-input-libinput package installed?

Re: [SOLVED] Touchpad suddenly stops working

I'm just using openbox, no DE, with autologin and no display manager. I haven't even touched anything related to the touchpad, it would be working out of the box with the default configuration from libinput and xf86-input-libinput... until it isn't. I do get "unable to enumerate usb device" messages which I suspect might have something to do with it.

Re: [SOLVED] Touchpad suddenly stops working

Do you have some power saving utility like TLP/laptop-mode-tools/powertop? If so you might have to blacklist the touchpad from the USB autosuspend list.

Re: [SOLVED] Touchpad suddenly stops working

It's a pretty fresh install with pretty minimal packages installed, I haven't changed or added any power saving utilities/settings. Literally the only thing I changed in a power saving sense is I set the lid switch to hibernate in logind.conf. I did see a different thread talk about auto suspend on a different site, can something else be causing auto suspend on the touchpad?
