I could probably do that, but first I need to find the halio module, after
all that R & R, its on the missing list. No, reinstalled a couple packages
again, and now its alone in /usr/lib/camunits, but can't be found by
camview. Everything else is in /usr/local/lib/camunits ??
so to test, I copied it to /usr/local/lib/camunits/halio.so but now its an
instant segfault. Damn I wish we had some docs on setting this up...
FWIW, 'cheese' sees it at higher resolution settings than camview even when
camview is working. So the camera proper IS working.
Cheers, Gene
