Hi,
I run Chimaera Devuan on Thinkpad T580. Periodically, about once a day, the
touchpad stops responding to all actions. It doesn't scroll or move the
pointer. During these blackouts dmesg doesn't display any messages and I
still can use the trackpoint. After a short period of time, around 1
minute, the touchpad becomes active again.
I would be grateful for any ideas that might help solve the issue.
'xinput list-props 12' produces the following output:
