I posted a couple of weeks ago concerning my trials and success getting a
dual headed VGA/mono setup working on my Linux box.  It worked excellently,
though the mono card was a bit slow.  However, as of last week, the monitor
was fried when trying to bring it up from a presumed sleep mode.  I want to
find out what gives before trying to install a replacement!  A student of
mine with an interest in electronics thinks the trouble is a burned dual pin
IC near where the main cathode ray tube plugs in.  There was smoke, but this
is all we (he) could find.

My apologies for wasting the bandwidth for this discussion of a subject with
of fairly limited general interest.  This might be a linux specific problem,
but I'd like to ask members of this list, who might know, if there is
something inherently strange about trying to plug in a mono monitor to a
modern motherboard (ASUS P55 T2P4 w/ Award bios).

An electronics teacher at our school indicates there is a possible problem
with sleep mode in conjunction with those old monitors.  Checking the bios,
I found that power management was diabled (but does anyone know if linux
does something on its own?---I'll check this elsewhere).  Virtually every
possible power management mode is disabled.

I had left both monitors on overnight.  I normally turn off the SVGA monitor
(energy star capable Mag Innovision), as well as, recently, the mono
monitor.  The SVGA monitor seems to go into some kind of sleep mode after a
fairly short period of inactivity; this hasn't been the case with the mono
monitor, but it has at least once gone blank and come back to life after
mouse motion or keyboard activity.

Thanks for the help and interest, previous to this; I'd appreciate any
pointers.
