<pre>Using the Debian Unstable and Experimental versions of xserver-xorg-video-intel
(2:2.21.15-2+b1 and 2:2.99.911+git20140529-1~exp2, respectively), the driver
does not set i915_enable_fbc=0 for HD Graphics 5000.
By default, the X session can only be displayed for less than one second at the
time. By switching away from X (Ctrl+Alt+F1), and then back (Ctrl+Alt+F7), I
can see a working X session for less than a second.
Setting i915_enable_fbc to 0 seems to allow for normal X use.</pre>
