13. Shared memory settings

Code:
sudo vi /etc/sysctl.conf

added this

kernel.shmall = 134217728
kernel.shmmax = 134217728

This is from dmesg for the non working cam a Logitech Quick Cam Pro 9000 with the uvcvideo driver. this one is plug-n-play in stock Ubuntu 7.04

ZM uses the V4L driver so any drivers for your cam will need to use V4l.
UVC and V4L2 are not supported.
