Let's see what I discovered step-by-step: $ evemu-record /dev/input/event23 error: this device is grabbed and I cannot record events see the evemu-record man page for more information $ fuser -v /dev/input/event23 USER PID ACCESS COMMAND /dev/input/event23: mario 1353 F.... libinput-debug- mario 1389 F.... gnome-shell $ ps aux | grep libinput mario 1337 0.1 0.0 41556 11856 ? Ss 11:35 0:00 /usr/bin/python3 /home/mario/.bin/libinput-gestures mario 1353 0.2 0.0 35736 4252 ? S 11:35 0:00 libinput-debug-events $ systemctl --user stop libinput-gestures.service (external trackpad started to work! the internal one of the XPS 13 worked in any case with any version of libinput) $ systemctl --user start libinput-gestures.service (now libinput-gestures gather gestures from both the trackpads) It looks something changed in libinput and this create badly conflict with the (weird) method used by libinput-gestures to gather event notifications. Note the I use libinput-gestures option 'device all' in order to catch events from multiple devices: including the device attached after service launch. I think this is the schedule in my system: - libinput-gestures launch libinput-debug-events; - the external bluetooth device is later connected. Is it normal that libinput doesn't make the external device to work if an instance of libinput-debug-events is running? As proof of this: if after the previous steps (so with everything working) I switch off the bluetooth trackpad, wait some seconds and reconnect it: the problem is there again.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
