Dear Maintainer,

Laptop Dell XPS 15 9530,
and also the same bug on Dell Precission 5570.


While normal work during whole day, left mouse button stops working.
I try to debug problem, it takes a few minutes, and button starts
working again.


For example I run as root:

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

and I get:

     #     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)
     E: 0.694903 0001 014d 0001    # EV_KEY / BTN_TOOL_DOUBLETAP 1
     E: 1.072529 0001 014d 0000    # EV_KEY / BTN_TOOL_DOUBLETAP 0
     E: 2.109761 0001 0110 0001    # EV_KEY / BTN_LEFT 1
     E: 2.178465 0001 0110 0000    # EV_KEY / BTN_LEFT 0


BTN_LEFT doesn't occur, left button doesn't work,
and after a minute or two i see BTN/LEFT again occuring.

They report that if left button stops working,
you just stwitch to another virtual terminal Ctrl+Alt+F3,
then go back again to X Window system and left click works again.

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.
