libinput-debug-events output using libinput 1.10.7
'libinput debug-events --verbose' output with interaction with the MTP |

What does libinput debug-events --verbose say when you interact with the device? (In reply to Peter Hutterer from comment #1) > What does libinput debug-events --verbose say when you interact with the > device? Nothing. See the new attachment. Created attachment 140002 [details]
'libinput debug-events --verbose' output with interaction with the MTP
very weird. evemu-record shows events? Please attach an event sequence here from that device. Ok, it looks that the problem is the use of libinput-gestures (that uses libinput-debug-events to gather events).
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.
tbh, no idea where this comes from. libinput itself doesn't grab the device, libinput debug-events has an option to grab it but it's off by default. libinput-gestures doesn't appear to be using that option though. And I can certainly run two libinput debug-events instances here without issues. I can't find anything in the libinput-gestures git history that used a grab, so *shrugh* I don't know, sorry. The way to reproduce the bug using, for example, an external bluetooth device like mine: - stop, in my case, any libinput-gesture instance; - disconnect the device; - launch 'libinput-debug-events' without options; - connect the device. Here on trackpad usage: from the libinput-debug-events output I can see the device to be removed/reattached and the correct events reported; the mouse pointer is completely stuck. If I stop libinput-debug-events, everything starts to work....

Can you reproduce it with upstream libinput? Just build it and run libinput debug-events from the build dir (sudo ./builddir/libinput-debug-events). Run evemu-record after starting debug-events - is the device listed as grabbed? -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 139971 [details] libinput-debug-events output using libinput 1.10.7 On my Arch Linux switching on libinput 1.10.7 made my external Magic Trackpad completely "muted". The device continues to (bluetooth) connect but it doesn't raise any event. To make all works again is enough to switch back to libinput 1.10.6. It is very strange... In attach the output of libinput-debug-events using libinput 1.10.7. The output is almost the same using libinput 1.10.6. I can provide any further detail that can help.
