I've tested to launch luvcvideo on GNOME instead of KDE and I get an error
message :
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
Unable to set format: 16.
Init v4L2 failed !! exit fatal
I tried to use software option -L and I get this :
/dev/video0 does not support read i/o

Do you have any hints about the problem? maybe something to check?
