Description Daniel 2020-06-10 21:28:52 UTC
SUMMARY
With the ThinkPad X1 Yoga 4th, the tablet mode (which disables keyboard, trackpoint and trackpad) isn't correctly enabled when the screen is folded over **after waking up from hibernation**.

WORKAROUND: Suspend and wake up again. Then the tablet mode works again.

TO REPRODUCE:
1. Go into hibernation mode.
2. Wake up from there.
3. Fold over screen.

OBSERVED RESULT:
touchpad,keyboard and trackpoint still work

EXPECTED RESULT:
touchpad,keyboard and trackpoint should be disabled.

acpi_listen doesn't report any events when the tablet is folded into tablet mode when in the state described above.
