Comment 2 for bug 1349749

TerminalDisplay.cpp
    m_font = QFont("Monospace",16);

Tried with
"Ubuntu"
This caused other issues, but worked

Tried with
"Ubuntu Mono"
Worked fine. No disappearing; Some aesthetic issues though, probably having something to do with this:
"file:///home/akiva/Programming/build-ubuntu-terminal-app-Desktop-Default/src/app/qml/Terminal.qml:171:9: QML Row: Cannot specify left, right, horizontalCenter, fill or centerIn anchors for items inside Row. Row will not function."
For whatever reason; Ubuntu Mono was the only font that did that. It caused the page header bar to disappear

Tried with
"Serif"
Worked fine

Tried with
"Courier"
Worked fine
