I've been using x11/nvidia-driver from ports on a Dell Latitude
C840 laptop with 4.8-STABLE.  I have it set to do 1600x1200.  The
problem is that whenever I close the cover while it's running X,
and then reopen the cover, the display is screwed up.  Specifically,
it looks like the left-hand half of the screen has been stretched
to cover the full screen, and the right-hand half is gone.  When
this happens, I can recover by doing Ctrl-Alt-F1 and then Ctrl-Alt-F9.
Or I can cycle through video modes with Ctrl-Alt-KP+.  But sheesh,
it's annoying as all get out.  Below are the relevant parts of my
XF86Config file.  Any idea how to fix this problem?  BTW, I had no
problems like this with the VESA driver.
