gestures not working with simulated mouse button

[Shock]

Hi Tom,

I've got a Logitech Zone Touch T400 mouse which has two physical contacts/actuators under the middle button and each actuator can be pressed independently. The default behavior for the actuators is: the front actuator sends a keypress ( Super_L) instead of the middle button press and the back actuator sends an actual middle button press. I can do gestures with the back actuator but it's really uncomfortable so using a combination of udev/xkb I've remapped the front actuator to send a middle button press but I can't do mouse gestures in easystroke using the front actuator.

Using xev I can see no difference between using the back or front actuator and moving the mouse, but using easygestures -vvvvv nothing is displayed in the terminal when doing the gestures with the front actuator, only when doing the gestures with the back actuator. Is easystroke somehow hooking into the events stream below where xkb is doing the mapping to a middle click? On second thought it's prolly because easystroke looks for actual mouse buttons ( grabbing: Button )...

Is this fixable in some way? Thanks!

$ easystroke -vvvvv
