/FHQ6:  Does DESQview support Super VGA?/FB



Yes and no.  When DESQview is placing windows on the screen, it cannot
use any of the 132 column modes provided by Super VGA cards.  The
smallest text font that DVC and DV386 provides to VGA+ users is 60 rows
by 80 columns.  Since video support is hardcoded into DVC and DV386,
there is no way to write a video driver for Super VGA cards.  DESQview//X
does support small fonts, included fonts that scale automatically to the
size of the window.  DVX supports many, but not all SVGA cards (see
below).



Inside a window, any resolution can be used.  The problem occurs when
you switch away from the window and come back.  DESQview will corrupt
the window unless it has a resolution of 800x600x16 or less.  Except in
rare cases, DESQview cannot handle 256 colors at more than 320x200.  A
few cards will reportedly work at 1024x768x16 as well.  Note that at
these higher resolutions,  ``Graphics Pages'' in Change A Program must
be set to 4.



The Quarterdeck White Pages, available on SIMTEL20 and DVNet /JB(see Q7)/q7.txt/
discuss this problem in detail.
