Kui hdmi ekraani ühendan lahti, siis läheb ka läpaka ekraan mustaks ja jääbki - restart ei aita (pärast sisselogimist kaob ka pilt). Ctrl Alt F1 -ga saan sisse logida teise terminali. dmesg näitab sellist viga:

Xorg.0.log näitab sellist logi (logi algab kui lisan hdmi monitori ja viimane rida tekib kui eemaldan selle ning läppari ekraan läheb ka mustakse):
