On two systems with INTEL graphics F9 is a continuing source of frustration. 
One is HP and the other based on an ASUS motherboard.  I'm happy with 2D as
my objective is computation but I like to have the display area of my
monitor usable.  F8 and earlier worked, but the autosensing doesn't properly
pick up on the card monitor combination.  The ability to overide the
settings with xorg.conf is gone.  I submitted a bug report but there seems
to be very little coming from X on drivers these days.
