I am running Debian Buster on a Thinkpad X240, recently upgraded from Stretch when Buster went stable. The Synaptics (TM2749-001) touchpad and trackpoint started acting up with the upgrade. They both work fine on boot, but occasionally after waking from suspend both inputs go dead. Once they go dead, they do not revive on their own after later suspends. Plugging in a mouse still works. Reboot revives touchpads.
does show the touchpad and trackpoint are recognized. Capabilities listed as pointer. Full output:

Part of the issue I'm having with troubleshooting this is the switch to Wayland from Xorg in Buster. A lot of the Debian documentation still only goes as far as Stretch. (For example
https://wiki.debian.org/SynapticsTouchpad) Most of the troubleshooting recommendations for other distros also refer to xorg drivers and not libinput.
Any ideas here? Other diagnostics to run? Wayland is new territory for me.
