X11 is known to be monster.
LNO also has problems running under X.
Whereas the FrameBuffer version has less problems, and it's
spectacular to see the 'graphic screen' in console mode.
But now I remember: so was it to see V5 in console mode.
I've 'lost' the text and mouse on my V5; only the mouse pointer
is visible when it goes off the V5 frame. But I'm not going to spend
effort debugging it unless I can access my <log file> written in V5.
Otherwise it's just a journey going nowhere.
