Thanks, I'll try this.
few hours ago I:
1) install x11-drivers/xf86-input-evdev
2) place following to rc.conf.d/webcamd:
[tiger at laptop]:~>cat /etc/rc.conf.d/webcamd
webcamd_0_flags="-N Lenovo-EasyCamera-Generic -S 200901010001"
webcamd_1_flags="-N Synaptics-Large-Touch-Screen-SYNAPTICS -S unknown"
webcamd_enable="YES"
3) restart xorg but still no luck, possible I need change something on
xorg.conf?
[tiger at laptop]:~>grep -i input /var/log/Xorg.0.log
