xrandr -s is the old XRandR procotol, it should still work but it's not
clear if that is going to be a bug in xrandr misconfiguring CRTC or in
X server/ddx. If you can file a bug and include your Xorg.0.log along
with "xtrace xrandr -s anything" and if you can manage to get an
xf86-video-intel --enable-debug=full log for the above, then I can tell
you where the bug lies.

At any rate "xrandr --output eDP1 --preferred" is what you want.
