all ok. to use it with vim3 u need linux 4.9 V20190830 or Android VIM3_Pie_V190809 or later (linux 5 not usable yet). LCD and hdmi NOT working at the same time in linux and cannot be switched at runtime in X11. (in android they duplicate output). Lcd uses vertical orientation and hdmi horizontal (not possible to change it at request). however in fb-dev kms-mode (linux console vs X11) auto switching works just fine - only one display at a time is active with hdmi priority.
