ok, i'll get a chance to check that when i get into the workplace. but
is there any way to de-activate that checking within X? from what you've
written, i'm assuming that the X server sees what's happening, and
consequently scales back on the resolution as a result. is there
an option >> to tell X to simply ignore that and go with full WUXGA
no matter what?
Not that I know of. The HW is reporting to X what its capabilities are
and even if you tell X to ignore what the HW is saying the HW probably
won't respond to it very well. :-)
ok, i got a chance to boot the laptop first with no external HW
attached to VGA, then after attaching that HW. the salient parts of
the diff of the X log files, before and after:

well, that certainly verifies why my laptop ends up at 1152x864.
let's read on:

um ... ok. i have no idea how much of that is important since
the decision to go with 1152x864 seems to have been made already.
in any event, i'm open to suggestions. and i'm still unclear on
what is making the decisions above. the RADEON video chip itself?
based on what?
