I recently bought an official 7 inch touchscreen for my pi3.
I only only use the program Lakka.
Unfortunatly, since I connected the screen, my hdmi output is not working. (Black screen)
The only way I found to make it work is to edit config.txt with a lcd_ignore=1 command, but this is not user friendly as well.
Do yo have a better solution for me to switch the dsi port and the hdmi port easily ?
