i just bought a logitech quickcam communicate MP and im trying to set it up. i installed the uvc kernel module from yast for both pae and default kernels (i have and switch). right now im in the default kernel. i just installed xawtv to see if i can get a picture out of it. the device is listed in /dev as video0. i cant get a picture out of this though. i also tried gqcam and i get error messages. here is some output info.

its worth noting that i am using nvidia so i guess that i cant use dga (im not sure what it is even). the programs are just outputting blank immages and im not quite sure how to get it to work. the permissions for /dev/video0 are rw-rw---- for root:video and i am in the video group and i have run these commands as root.

does anyone know how to get this camera working?

ok actually it works in skype fine which is all i cared about but now i have a new problem. when i was trying xawtv i tried to change the contrast and the bar dissapeared and now in skype the contrast is way up and it shouldnt be. how do i change the contrast back? or how do i delete the xawtv settings?

#3

Often, the settings are automatic. I believe, though, that I tweaked them in luvcview, and they stuck (at least through the current session). I have that exact same camera.

Install luvcview and try.
