[CLOSED] Major issue : HDMI Vanishes

[Didier B]

When everything has been checked, the only eventuality left is the real one : my archive (2020-03-24-OpenPlotter-v2-Starting-img) was corrupted !
I downloaded a fresh img, burned an µSD card, and the ugly stinking bug was not there anymore ! No idea of how it happened ! And really very happy to have solved the case after the days wasted on it !

WGAI (whats good about it) ?
During these investigations I discovered the following :

1. In the downladed img, in raspi-config the OpenGL is activated !
   
2. In Raspberry Pi, OpenCPN 5.2 is not compatible with OpenGL : hitting the button "Rebuild texture cache" results in the brutal closing of the OCPN Option windows (when openGL is activated in both raspi-config and OpenCPN)!
   
3. Use of a "Noobs" download prevents any further file system expansion of any derived copy ;
