Xorg.0.log
On a MacBook Pro 11,1 (late 2013 13", Intel Haswell / Iris 5100), when acpid
detects lid close/open it'll call xset -display :0 dpms force off or on
(because for some reason the screen doesn't turn off by itself when the lid
closes). Meanwhile, before I close the lid, I manually run i3lock, but when I
open the lid up again the desktop is visible for a fraction of a second, and
then i3lock's blank screen reappears. This does not happen on another of my
machines with a Pineview Intel chip (GMA 3150 I believe). I understand that
this may not be a graphics driver bug at all, however since it only happens on
this Haswell chip it very well might be.</pre>
