[Bug 1791473] Re: Touchpad Elantech ELAN1200 does not get disabled in tablet mode of Asus ZenBook Flip UX561UD convertible laptop

[Mario Vukelic]

** Description changed:

- Sorry if acpid is not the right package for this. The blueprint for convertibles mentions /etc/acpi/twist-tabletmode.sh, though the blueprint is old and where this would be implemented may have changed:

  Repro:
  1. Fold display back to tent mode and further to tablet mode
  
- -> The touchpad should get disabled, but doesn't. The keyboard does get
- disabled, and so the mode is correctly detected somewhere
+ -> The touchpad should get automatically disabled, but doesn't. The
+ keyboard does get disabled, and so the mode is correctly detected
+ somewhere.
+ 
+ The touchpad CAN be disabled manually with the secondary Fn function of
+ the dedicated key.
  
  The touchpad is an ELAN1200 and the ELAN entries from libinput list-
  devices (under Wayland) are attached.

Title:
  Touchpad Elantech ELAN1200 does not get disabled in tablet mode of
  Asus ZenBook Flip UX561UD convertible laptop

Status in acpid package in Ubuntu:
  New

Bug description:

  Repro:
  1. Fold display back to tent mode and further to tablet mode

  -> The touchpad should get automatically disabled, but doesn't. The
  keyboard does get disabled, and so the mode is correctly detected
  somewhere.

  The touchpad CAN be disabled manually with the secondary Fn function
  of the dedicated key.

  The touchpad is an ELAN1200 and the ELAN entries from libinput list-
