left palm brushes touchpad
Ubuntu Linux 16.04.
There appears to be no palm detection as described in the exclusion zones
document
(<a href="https://wayland.freedesktop.org/libinput/doc/latest/palm_detection.html">https://wayland.freedesktop.org/libinput/doc/latest/palm_detection.html</a>). I'm
attaching evemu-record output when brushing touchpad from outer edge with palm.
I've tested quite a few different kernels, the result does not change much.
Many other touchpad features work fine. I can move the cursor smoothly, tap to
click is fine, middle click emulation is good. Disable while typing works as
expected, except that the instant I pause, the cursor flies somewhere else and
I type in the wrong spot. I don't get dependable result from the three-finger
tap. About 1 time in 10 I can get three-tap to trigger a middle event. However,
a two-finger tap does work as a right click very dependably. I fairly often
have the problem that the cursor flies to an outer edge at the instant I left
click. I cannot tell if that is linked to palm detection, but I guess yes.
This may be irrelevant to you, but I notice some trouble in the event recording
playback. When I brush touchpad with palm, cursor moves inches on the screen,
but when I do the playback, the cursor moves only 10% as much.
I tried pretty hard to get the info you ask for. I hope this is it!
