this spam is free . . .
and replacing a fried monitor costs big bucks . . . .
but i won't be replacing any monitors

has this monitor ever worked? on what kind of chipset/video card or
whatever?

a video chipset, card, whatever, is translating for your monitor,
so you can't configure for a monitor only when trying to use the
Xconfiguator
in other words, a configuration with one boxes board or a specific video
card
won't necessarily work the same for the monitor on a different
box/card/chipset . . . .

XF86Config is the place to be, as kai and steven pointed out, but they
found they could
change the resolution only to lose the mouse/pointer.  peter, paul,
anyone . . . .

you probably already know all this, but i like to hear myself type, so .
. . .

VideoModes.doc is a good read for this type of adventure -- it'll say
stuff like
   modeline is a card(chipset)/montior combo -- the chipset allows the
memory map.
   XF86setup limits itself to 1280X1024 ( your monitor fits right in!)
    and you don't have to abide by the 4:3 aspect ratio, so though it
limits itself
    you can configure beyond its limits.
   horizontal pulse syncs have to be divisible by 8 -- vertical pulses
don't

the maximum resolution, the frequency pairs, and the maximum bandwidth
given
allow you to point close to the VESA standard of 72Hz,  though some
experimentation
is required.

you could use SuperProbe to determine what chipset you're using . . .
when i run it from the cmd line here, with these switches,
>SuperProbe-verbose-no16 -no_bios
this system returns --
Super-VGA
  Chipset: S3 Virge (PCI Probed)
  Memory: 4096K
  RAMDAC: Generic 8-bit pseudo-color DAC
                      (with 6 bit wide lookup tables (or in 6 bit mode))

once the chipset stuff is figured into your calculations you might get
some video

there's also a utility i've only heard of -- xvidtune
you have to know the monitor's every spec to use it , i guess., but i
never have used
it

somebody with an ear for aclug can probably help more -- wasn't the last
meeting
on X?

so, you get X started -- but nothing shows up.
what window manager are you using?
are you using the startx script?

anyone got any ideas?
