I disabled it and also disabled the sync_to_vblank. with only the detect_refresh_rate trick I could switch and back to the console but not to another X display. Now everything is mostly okay. Last bug I noticed : my gnome-panel with a transparent background was completely transparent (but still there with all its applets) after coming back from another X display. Just changing its background restored it.
