Newby troubleshooting.

  • I've just installed LibreElec on a Raspberry Pi... Twice because the first time I lost the picture and I couldn't find a way to get it back.
    So now I have a few questions, starting with how to open a terminal, since this opens various doors to solutions...
    But the issues that I've really got is to change the screen size or resolution because the picture is bigger than the screen.
    also, how do I change it to HDMI?

    Finally (for now) any top tips on getting a Wifi dongle to work?
    Possibly it isn't an RPi compatible dongle, I'll check that in a shortly...
