I updated my installation a week ago. After updating I closed the lid for about half an hour. After resuming from sleep the touchpad has been completely unresponsive and somehow it has persisted into my windows 10 installation. Does anybody know how to troubleshoot this? I’m desperate at this point.
Thanks in advance.
Does this also prevent the machine from going back into sleep mode?
… Without knowing what hardware you have, a stab in the dark:
sudo modprobe -r psmouse && sudo mpdprobe -a psmouse
A similar command may be appropriate depending on which touchpad you have.
Also, please have a read of this as it may help you to help us to help you:
How to provide good info 
It doesn’t prevent the machine from sleeping.
Thanks for your help but the psmouse commands didn’t seem to fix the problem.

I came upon this discussion that seems similar to my problem but I’m not sure:
https://bbs.archlinux.org/viewtopic.php?id=252711&p=2
Does sudo rmmod i2c_hid && sudo modprobe i2c_hid solve the problem?

I’d suggest that too along eith trying other kernels i.e. one of the LTS versions and not necessarily the latest version thereof. I have experienced issues with Acer Asppire trackpads (also Toshiba ones) and this might also be the case with the OP’s machine.
Plus those ACPI issues on the Toshiba machines… but that’s a subject for another thread …
I’ve tried pobrn’s solution and downgrading the kernel to 5.4 LTS but still no luck. At this point I don’t even care if I have to wipe my Manjaro installation and start over. I just need it to start working again in Windows.
