What graphics hardware do you use? I have an Nvidia 8800 GTS. I do not know how well this option works for other hardware. Also, what type of acceleration are you using for your X driver (check /var/log/Xorg.0.log). EXA may be required over XAA. At least, some type of acceleration is needed. I am new to this option, so that is all I can surmise. Sean -- scf@FreeBSD.org
