Description Michael Hill 2018-05-28 17:39:49 UTC
Description of problem: ThinkPad Bluetooth keyboard causes the cursor to disappear or become unresponsive.

Version-Release number of selected component (if applicable): Version: 1.10.901
Release: 1.fc29

How reproducible: on Wayland, connect ThinkPad Bluetooth keyboard, access the GNOME Shell overview; on X, make contact with the TrackPoint on the same keyboard.

Actual results: on Wayland, after activating the shell overview, the cursor vanishes. I can get it back by disabling Bluetooth from the system menu and switching to a console (Ctrl-Alt-F3) and back.

On X, the keyboard works until I touch the TrackPoint. The cursor flies to the shell hot corner, lights up Activities without opening the overview, and stays. My laptop TrackPoint or a USB mouse can then be used to move the cursor. The Bluetooth keyboard can still be used for typing.

Expected results: the cursor remains active and accessible when using the Bluetooth keyboard.

Additional info: Kernel Version: 4.17.0  Release: 0.rc6.git2.1.fc29, 0.rc6.git3.1.fc29; gnome-shell Version: 3.29.2 Release: 1.fc29

Comment 1 Michael Hill 2018-05-30 12:34:00 UTC
Clarification: on Wayland, the first touch of the trackpoint *causes* the shell overview to open, after which the trackpoint is unresponsive.

Comment 2 Michael Hill 2018-05-31 19:24:37 UTC
Also with libinput Version: 1.10.902 Release: 1.fc29, Kernel Version: 4.17.0  Release: 0.rc7.git0.1.fc29.

Comment 3 Matthew Miller 2018-05-31 21:30:37 UTC
I have the exact same problem with the versions of libinput currently in updates-testing for F28 (libinput-1.10.902-1.fc28.x86_64 and libinput-before that 1.10.901-1.fc28.x86_64). I've tried on various 4.16.x kernels with same result, but reverting to libinput-1.10.7-1.fc28.x86_64 solves it.

However, my keyboard is the *USB* version of the ThinkPad keyboard, not bluetooth.

Comment 4 Peter Hutterer 2018-05-31 22:55:48 UTC
Is there any chance you can bisect this with git master? I have no idea where this is coming from and I have failed so far to reproduce this with virtual devices (i don't have an external trackpoint).

Bisecting is easy enough, running sudo ./build/libinput-debug-gui gives you a GUI where the cursor is controlled by libinput motion events directly. This should be enough to check if the bug is there.

You'll need gtk3-devel at meson build time to build that tool.

build instructions otherwise are here:

but it's a basic meson build, nothing exciting.

Comment 5 Peter Hutterer 2018-05-31 23:01:10 UTC
Also, I'll need the libinput debug-events --verbose output from such an event (should show the delta at least) and the udevadm info /sys/class/input/eventX output for the event node from the trackpoint.

Comment 6 Matthew Miller 2018-06-01 00:36:32 UTC
I can. Does that debug gui work with the built library in situ or do I need to actually install and restart X?

Comment 7 Peter Hutterer 2018-06-01 00:42:58 UTC
Works in situ, no restarts needed. I'm hoping it's not some udev-related bug because then you'd have to also run

sudo udevadm hwdb --update
sudo udevadm trigger /sys/class/input/eventX

before each test run. Should be safe to do so anyway though.

Comment 9 Matthew Miller 2018-06-01 01:07:52 UTC
Okay, so, libinput-debug-events gives me 

event10  POINTER_MOTION    +2.22s  -0.07/  0.00
event10  POINTER_MOTION    +2.24s  -0.62/ -0.21
event10  POINTER_MOTION    +2.26s  -1.90/ -1.14
event10  POINTER_MOTION    +2.27s  -4.91/ -3.07
event10  POINTER_MOTION    +2.29s  -8.32/ -6.66
event10  POINTER_MOTION    +2.30s  -8.74/ -7.87
event10  POINTER_MOTION    +2.32s  -7.04/ -6.26

with the old lib, and THIS with the new one

-event10  POINTER_MOTION    +1.93s	   inf/  -nan
 event10  POINTER_MOTION    +1.94s	   inf/  -nan
 event10  POINTER_MOTION    +1.95s	   inf/  -nan
 event10  POINTER_MOTION    +1.97s	   inf/  -nan
 event10  POINTER_MOTION    +1.98s	   inf/  -nan
 event10  POINTER_MOTION    +2.00s	   inf/  -nan

that's some smoking gun stuff right there :)

Comment 10 Matthew Miller 2018-06-01 01:58:52 UTC
Workaround from Peter: create /etc/udev/rules.d/99-test.rules with

ACTION!="add|change", GOTO="test_end"
KERNEL!="event*", GOTO="test_end"



then run

sudo udevadm hwdb --update
sudo udevadm trigger /sys/class/input/event10

(or whatever input/eventX corresponds to your device)

for the archives, ^^ is the revert of the commit that introduced this bug and should make things normal again. It may have effects on some other devices, still looking into this. I'll try to add this bug number to future updates, please keep testing those too so I know if I accidentally break this device again. Thanks.
