GDM can't show and screen freeze after screen saver and turn off backlight 
command("gnome-screensaver-command -l;sleep 3;xset dpms force off")
But, if you press Ctrl+Alt+F3(tty3) then press Ctrl+Alt+F2(tty0), GDM will show.

Dmesg:
[11577.928164] [drm:intel_dp_set_link_train] *ERROR* Timed out waiting for DP 
idle patterns
[11577.928167] [drm:i915_write32] *ERROR* Unknown unclaimed register before 
writing to 64040

Expected output: it enter to screensaver and turn off backlight, then
press any key to resume system, it should shows GDM.

This only happens on Haswell chipset, but it is OK on Ivybridge.
