:I would guess that the Xenix flavor of VP/ix also shares this misfeature.

I'm running 1.01.00 VP/ix under Xenix, which (I think) is the current
version.  As with previous versions, I substitute an image of the
Genoa SUperEGA HiRES rom for the supplied ROMEGA file.  This allows
the higher resolution modes etc. to be used.  Unfortunately, the
Genoa EGA ROM does not know how to handle the screen swapping functions,
so one must be careful not to swap screens while the Genoa ROM image is
being used.  I have recommended that SCO and/or ISC document these
extensions to allow Genoa et al to support the combination of VP/ix
and multiple screens.

With the current VP/ix version, it is usually possible to put things back
in order with a kill -1 given from a serial terminal.
