Comment 0 for bug 1786602

Immediately after choosing "Lubuntu Qt" session at login time, a small window appears with the message:
unable to launch "/usr/bin/startlxqt" as session --- "/usr/bin/startlxqt" not found; falling back to default session.

There's an "Okay" button. After pressing the button, the system crashes.

In /usr/share/xsessions, there are three files:
Lubuntu.desktop openbox.desktop QLubuntu.desktop

The content of QLubuntu.desktop are:
[Desktop Entry]
Name=Lubuntu Qt session
Comment=A specific Lubuntu session using Qt
Exec=/usr/bin/startlxqt
Type=Application

I suggest that QLubuntu.desktop be removed from future point releases of Lubuntu 18.04, or earlier if possible, so that users cannot login into the session it appears to provide.
