When using the hdmi, /dev/fb0 is available and not /dev/fb1. The change check if /dev/fb1 exists and when not , switch to /dev/fb0

Interesting find. Does "using the hdmi" means that a HDMI display is "connected"? Because this could also then be used to "auto-detect" what is at the moment a "manual switch": https://github.com/rootzoll/raspiblitz/blob/v1.6/FAQ.md#can-i-run-the-raspiblitz-without-a-displaylcd |

I have connected the hdmi to a 7zoll LCD. The hdmi is always /dev/fb0 and the spi display is always /dev/fb1, I think it is possible to use fb1 and fb0 for autodetect. |

@holgern did you tested this also with the LCD hat on and Touchscreen on? In my tests with the PR it does not show the images/qr anymore and instead shows the pi-terminal. Will push this PR to v1.7 milestone. |
