After update to 1.1.7 problem is not solved.

Comment 2 Peter Hutterer 2016-02-16 07:09:22 UTC

I need an output from evemu-record please. Just record yourself with the finger still on the touchpad for a few seconds. Thanks

Please don't link to pastebins, they have a tendency for disappearing. Sometimes we need information in bugs at a later point (or don't get to it for a while). Attaching files is always the better option.


Anyway, this is the file from the pastebin attached, touchpad is a synaptics semi-mt device.

same touchpad as bug 94097, merging the two bugs together
