Slow xorg after upgrade

[Chris Hill]

Thanks to all who replied; it's fixed.

Adam, you hit the nail on the head. It turns out that xorg was looking 
for intel_drv.so, which is correct, but that driver had "somehow" 
vanished from /usr/local/lib/xorg/modules/drivers. Failing to find the 
Intel driver, xorg fell back to the modesetting driver.

I didn't expect a previously-working driver to be deleted like that, so 
it wasn't the first thing I looked for. Anyway, the fix turned out to be 
as simple as
   # pkg install xf86-video-intel

Thanks again.
