Posting this as a reminder for myself (mostly) and anyone else that happens to land here after an internet search (welcome to the forum, check out VSIDO).
After installing and working with Void linux on a Toshiba Satellite, the touchpad quit working. Normally, I use a script to toggle it off when the window manager starts since I typically have a usb mouse attached. After about 2 days the touchpad just quit working - couldn't toggle it back on, and it wouldn't work at grub menu or login screen.
Turns out this Toshiba Satellite (and some other laptops) has a special function key binding (FN + F5) that toggles the touchpad on/off. I apparently toggled it off when using xev to ket the various keysyms.
The issue is that the touchpad remains off upon reboot. So a quick FN + F5 solved my problem.
Yes Toshiba laptops are weird birds and I generally avoid them for using with Linux.
