Hi Wade If you look at nv17_tv.c it will answer all your questions It boils down to nv17_tv_set_property() * if (property == conf->tv_mode_property) { if (connector->dpms != DRM_MODE_DPMS_OFF) return -EINVAL; * if (property == conf->tv_select_subconnector_property) { if (tv_norm->kind != TV_ENC_MODE) return -EINVAL; For a list of TV_ENC_MODE vs CTV_ENC_MODE take a look in nv17_tv_modes.c Have fun :P _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
