Collect libinput events together with the evdev events and print them to the
log. This makes it possible to debug the full behavior of a user's machine
rather than having to replay it with potential different race conditions/side
effects.
Example event output:
- evdev:
- [ 2, 314443, 4, 4, 57] # EV_MSC / MSC_SCAN 57
- [ 2, 314443, 1, 57, 1] # EV_KEY / KEY_SPACE 1
- [ 2, 314443, 0, 0, 0] # ------------ SYN_REPORT (0) ---------- +87ms
libinput:
- {time: 2.314443, type: KEYBOARD_KEY, key: 57, state: pressed}
- evdev:
- [ 2, 377203, 4, 4, 57] # EV_MSC / MSC_SCAN 57
- [ 2, 377203, 1, 57, 0] # EV_KEY / KEY_SPACE 0
- [ 2, 377203, 0, 0, 0] # ------------ SYN_REPORT (0) ---------- +63ms
libinput:
- {time: 2.377203, type: KEYBOARD_KEY, key: 57, state: released}
Note that the only way to know that events are within the same frame is to
check the timestamp. libinput keeps those intact which means we can tell that
if we just had an evdev frame with timestamp T and get a pointer motion with
timestamp T, that frame caused the motion event.
So far, only key, pointer and touch events are printed. We also
hardcode-enable tapping where available until we have options to enable this
on the commandline just because that's useful to have.
