Or even downright bizarre! Can you disable the caching (hopefully the patch is still revertible) and save the EDID (/sys/class/drm/card0-LVDS-1/edid) periodically? Might be simplest just to dump the EDID every time we probe the LVDS if it has changed. -Chris -- Chris Wilson, Intel Open Source Technology Centre -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
