haunt" at 7pm.
Topic: general discussion / using linux to drive a Curio die cut machine.
San is and refreshments will be provided and afterwards we'll head off for
dinner to continue the conversation.
See ya there!

WLUG President
I wanted to know if OpenAlchemist is included in Debian. During my
searching I found distrowatch has the ability to compare packages from
distributions. I pull up Fedora and Debian.
https://distrowatch.com/dwres.php?resource=compare-packages&firstlist=fedor…
Fedora's list of packages doesn't include OpenAlchemist. Nor does it
include shippy, ostrichriders, and btbuilder. Clearly this isn't a
complete list. Am I doing something wrong on distrowatch? Is there a
different way to do the same thing?
Hey Gang,
I'm going to move the meeting to August 15th.
If you've got a topic idea, let me know. Otherwise, we can either do an
open topic meeting.
Thanks,
Tim.

Maybe "(not using libv4l2):" is my problem? Do I need a webcam app that
specifically supports gspca?
Anyway, I added myself to the 'video' group and ran Cheese.
Since I was already in the terminal, I ran Cheese from the command line
instead of from the GUI, like I usually do, and I was rewarded with some
extra output (editing out some irrelevant lines):
> Xlib: extension "RANDR" missing on display ":0".
> (cheese:8484): cheese-CRITICAL **: 10:26:20.051:
cheese_camera_device_get_name: assertion 'CHEESE_IS_CAMERA_DEVICE (device)'
failed
Cheese still didn't find a video device, and I got the same results running
it as root.

I picked up a Creative Labs model VF0250 webcam, but V4L isn't detecting
any devices. I googled it and it looks like gspca supported this model,
but it also looks like gspca was abandoned years ago. Where would you look
for answers?
BTW, this is for Mint.
