Re: nvidia drivers mutex lock

Hi _at_tomoaki
Is that version of nvidia drivers currently in the ports tree? I just
checked but it seems not to be.

_at_jeffrey
I just generated a new xorg based on the force composition setting. I
merged it with my previous xorg I'll reboot, see if it gives better
performance.

It seems like my system is locking up more frequently now. Sometimes right
after a reboot the system, the screen locks and it's reboot and pray.

Best,
Owen
