Hello,
I started with a fresh X-Plane 11 install and only installed the TBM 900.
I am not seeing the UI, no plugin is shown in the plugin menu, and no click areas react to a click.
I am using kubuntu 18.04
Errors I noticed in the Log.txt file:
dlerror:/home/ryan/Games/X-Plane 11/Resources/plugins/Gizmo64.plugin/64/lin.xpl: invalid ELF header
