Transparent (hidden) cursor for Gnome / Wayland
While trying to hide cursors for a kiosk in the latest Raspbian Buster, all my old tricks didn't work. This was mainly due to it using Wayland. Wayland doesn't have the -nocursor option that X does.
Any hoo, I have never loved the old solutions I used anyways, since they requires addition software (unclutter) or, moving the mouse to 0,0 (which left 1 px showing).. Or, adding in some css, which chromium seems to break on occasion.
Download the transparent file and overwrite any pointer file you want to hide. In the case of Wayland on Buster that file is:
/usr/share/icons/Adwaita/cursors/left_ptr
This file was generated with the xcursorgen command. You can duplicate the creation by running:
xcursorgen transparent.cfg transparent
or, in the case of the left_ptr file:
xcursorgen transparent.cfg left_ptr
