Update, I swapped that M$hit camera for logitek's best today, but that made zero difference. However, I did get it to work, see: <http://wiki.linuxcnc.org/cgi- bin/emcinfo.pl?TroubleShooting#Installing_Software_based_OpenGL> where: sudo apt-get install libgl1-mesa-swx11 rips out a bunch of stuff starting with freecad, but on the reboot, it Just Worked(TM) Now I have to figure out how to mount the much wider logitek device, which comes complete with (oh goodie, don't know how I lived without them before NOT! :) stereo microphones. FWIW, its auto-focus too, down to about 1.25" from the face of the camera, a 2" dial indicator more than fills the window. At full resolution, 15 megapixels. It also gets bitches from libv4lconvert that it cannot handle that many ultra hi res frame specs, but it goes ahead and works anyway. So that problem is solved, now to get all the buttons properly enumerated so they do what they claim to do. S/B fun because I don't think I have it right at the moment, some confusion between the [HALUI] stuff and campins.hal & maybe even in camview itself.
