Regarding the "patronising" part, it may well have been the solution.

I haven't encountered the same problem, for a while now; it seems to 
have happened for a few days, and then, not since then (funny - after I 
queried on this list, and then got some responses, the problem appears 
to have disappeared for the time being).

Sometimes, when moving to and from the chair at which I am sitting when 
using this computer, I bump the desk, and the display fails. I then 
jiggle the VGA lead that goes into the monitor (the plug for the lead, 
is connected vertically - hanging down from the socket in the back of 
the monitor), and, just then, when looking at the connection, I bumped 
the VGA lead with the mirror, and got "No signal" on a black screen on 
the monitor, which I then overcame, by jiggling the lead, to restore a 
stable(ish) connection.

One thing about it, that puzzles me, is that the problem with the 
flashing off, then on again, as previously mentioned, and the increasing 
frequency, happened only when (and, immediately after) a session using a 
terminal or console thing, thence using the command line, and, did not 
appear when just using the GUI without the command line.
