I was looking at the file Steven provided, which has modelines only for
640 and 480.  On another computer I have the config file that I got
working with a Virge card that shoudl have the other modelines.

So I should figure out the lowest frequencies for a 1024, and use those.

Let's assume my monitor does only 1024.  Some do more.

That is more like it, but can I have a virtual desktop of 2000 or so?

It refused to compile, I forget why.  It would compile for X but not svga
or even vga (which the SW71 gs supports, though not as default).  The SW81
gs does not provide svga or vga either.  I selected them as devices but
could not get it to compile even with lots of help.  I had problems
compiling jasper first, and we had to edit one file so it would not look
for Windows.  So I gave up and compiled for X as the only display device.

I need some way to zoom and the virtual desktop might do it.  I need to
actually see all the dots in something scanned at 300 dpi, and if my
monitor is 12" across that would be 3600 dots, so I need a virtual
desktop.

But not all video chips will do more than 8-bit color, esp. laptops.  That
is the main problem with Xvesa or xfbdev.

Yes, and XSVGA may or may not work on those two laptops.  I will try out
Steven's package on them some time this week, at 640 res.

Xvesa works with Vesa 1.2 just fine.  8-bit color is the problem.
