You have to do what was suggested before:
Code:
$ cd /usr/ports/x11-drivers/xorg-drivers
$ make config
The Intel 810 driver is broken, so you need to make sure it is not installed. Once you do the "make config" you will get a display of the default video drivers that xorg will install unless it is changed. Uncheck the box by the Intel 810 driver. Then install (or upgrade) xorg.
