Bug#1108441: Info received (Bug#1108441: Acknowledgement (xserver-xorg-input-libinput: Left clicks stop working every few hours, freezes for a minute or two))

Typical example.


If touchpad stops responding to clickc, I immediately run terminal as root,
run command as below, and start double clicking.

Click not works, so touchpad shows only Double Tap.

After 13 seconds clicks work again, and both BTN_LEFT and DOUBLETAP are 
received:

Some more testing...


Switchijng to another console with Ctrl+Alt+F3 doesn't solve the problem.

Logging on text console maybe solves.
Maybe? Because mouse clicking hangs for one minute and maybe I'm not 
fast enough.






My curent solution is to:

1. open terminal
2. switch to root user
3. run command, and click, tap, double click, double tap:

# evemu-record /dev/input/event4 | grep BTN --line-buffered | grep -v 
'BTN_TOUCH|BTN_TOOL_FINGER|myszbuttontest'  -E

# Event code 272 (BTN_LEFT)
# Event code 328 (BTN_TOOL_QUINTTAP)
# Event code 333 (BTN_TOOL_DOUBLETAP)
# Event code 334 (BTN_TOOL_TRIPLETAP)
# Event code 335 (BTN_TOOL_QUADTAP)

When I see "BTN_LEFT", then touchpad starts clicking properely.
