I have been using the pi 3 with a little OLED (no local monitor) all worked well. I purchased a little 8 inch monitor (16:10) and updated volumio to the latest update.
I can interface with the pi via webUI, and it works perfectly, but all I see on my monitor is the
Welcome to Volumio
webUI available…bla bla
with vinceserver Login
How do i get the full display to work, and not as a terminal interface?
install the plugin touch_display 
Thanks…I tried to install the plugin, but it didn’t want to install got the following:
