+Subject: Handle CRTC DPMS from output DPMS hooks
+
+This fixes at least two issues:
+
+The CRTC DPMS hook isn't called after a modeset, so the vertical blank
+interrupt emulation code considered the CRTC disabled after a modeset. As
+a side effect, page flipping was no longer used after a modeset.
+
+This change also makes sure the vertical blank interrupt emulation code
+runs before the hardware CRTC is disabled and after it's enabled from the
+output DPMS hook. The wrong order could cause gnome-shell to hang after
+a suspend/resume and/or DPMS off/on cycle.
