[Solved] Touchpad inexplicably stopped working

I am running a dual boot Windows 10 and Arch. I first noticed that my touchpad wasn't working after I left my mouse (Razer Taipan, if that matters) plugged in on poweroff. Upon booting again, I couldn't use my touchpad at all. It was the first time I used that mouse on Arch though it seems unlikely that this could be the cause of my problems. The touchpad works on Windows. The issue persisted across a fresh install of Arch and a BIOS update, and does not seem to be the issue of accidentally pressing my Fn+F7 keys. I tried a liveUSB of Debian and the touchpad doesn't appear to work there either.

My laptop is an Acer Aspire E5-571. This is the output of xinput list:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ ELAN0501:00 04F3:300B Touchpad          	id=14	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]

    ↳ Video Bus                               	id=7	[slave  keyboard (3)]
    ↳ Power Button                            	id=8	[slave  keyboard (3)]

    ↳ Acer WMI hotkeys                        	id=16	[slave  keyboard (3)]

The output of xinput list 14:

Not sure what else I should provide, but I will if it helps with this problem. I'm fairly new to Arch (and Linux in general). Thanks in advance.

Yes, I did that before I first ran startx.

Re: [Solved] Touchpad inexplicably stopped working

you may try "libinput" in that case

sudo pacman -Syu fixed my problem. Still not sure what happened. Solved.
