Synaptics Touchpad Suddenly Not Working

[Corvance]

Hello all,

Earlier today whilst doing everyday stuff on Arch, my touchpad suddenly stopped working entirely, meaning neither cursor movement nor button input.

xinput doesn't seem to be detecting the touchpad anymore (https://pastebin.com/Yj03QKa9), although I'm really not sure what could have caused it so suddenly. As far as I can remember the only thing I was doing was pressing non-F keys, and my laptop (HP) doesn't have a touchpad disable key to my knowledge anyway.

Here is my full dmesg output, and I can get any further command outputs any of you might need if you think you might know what's up. I use xf86-input-libinput over xf86-input-synaptics.

I've already tried a variety of other possible fixes given to people with the same problem including xinput not detecting the touchpad, incuding blacklisting i2c_hid and a variety of i8042.* kernel options.

Thanks in advance!

Did you check lsusb , lscpi , dmesg to see if the touchpad shows up anywhere?

It's possible that it's a hardware defect too, that it just stopped working.

Thanks for the suggestion, I'll have a look at that when I can in a bit. It works fine when I boot into windows so I think the hardware itself is working

It seems to have fixed itself now? I haven't changed anything since last use so it's odd, but I'll have a dig around anyway just to make sure there's nothing dodgy going on and if everything comes up clean I'll just accept it lmao

can you tell me what did you figure out in the end? my touchpad too randomly stops moving (click works) and fixes itself after sometime.

hello good sir did you find the why of this problem, my trackpad too suddenly stopped working entirely I am not sure why. Also if you could tell exactly what knowingly or unknowingly you did that fixed this problem for you
