Please forward this message to the maintainer of the port x11/nvidia-driver.

NVIDIA's X11 driver needs much shared memory.
If kernel cannot provide enough shared memory to nvidia-driver and other
programs(e.g. Apache 2.2+PHP5) simultaneously, Xorg will freeze with NVIDIA's
logo on screen.

This problem has troubled many FreeBSD+NVIDIA users.
>How-To-Repeat:

>Fix:
Related prompt should be added to post-install message of the port
x11/nvidia-driver:

If Xorg cannot start and reports

   (EE) NVIDIA(0): Failed to obtain a shared memory identifier.

in /var/log/Xorg.0.log while actually you have enabled "options SYSVSHM" in
kernel, the sysctl "kern.ipc.shmall" should be increased.
