I've got a problem that's completely baffled me. A few days ago I
installed SANE 0.57, which I use with a color QuickCam (on /dev/lp1,
with the port in ECP mode.) This worked fine until today. In xcam, I
hit "play", get one image, and then xcam hangs (no new images, can't
pull down menus or click buttons, etc.) A similar thing happens with
xscanimage - I can scan one preview image, then the program hangs if I
try to scan another image.
I've tried undoing everything I've changed in the past day or so
(different color depths, different window managers, etc.) and nothing
changes. I've tried running as root, and it does the same thing (I
have xcam/xscanimage/scanimage installed setuid root so I can run
them as non-root.) I did upgrade to Red Hat 4.2 a few days ago, but
all was well yesterday with 4.2 running (at least, I think so.)
scanimage still grabs images just fine, and the QuickCam shows up in a
scanimage -L.
My machine is a Pentium Pro box w/ 64 MB RAM and XFree86 3.2, driving
a Matrox Millenium card at 1280x1024, 24bpp. I configured sane with
--enable-preload, since the QuickCam didn't show up in scanimage -L
otherwise.
I did an strace on xcam; the (gzipped) stderr from that is attached,
in case it offers any insights. I'm no kernel hacker, so I haven't
much of a clue in this regard.
scanimage is the one program I really needed, and that's working fine,
so this isn't too urgent, it's just frustrating. :-|
If I can be of any further help, please let me know.
