Touchpad scroll not working after unplugging usb mouse and keyboard

i don’t know if this is related to the input stuttering issue (which i experienced only with an external mouse and “fixed” by unplugging it and plugging it back in), but basically after a while of using the laptop “docked”, unplugging everything i noticed that the touchpad stopped working properly, with gestures not being recognised anymore. also, gnome touchpad settings were overridden by the mouse settings: changing the touchpad speed didn’t have any effect, while changing the mouse speed did. a reboot fixed all of this.

any clue?
