(totem:27938): Gtk-WARNING **: 15:09:23.719: Calling org.xfce.Session.Manager.Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: Method "Inhibit" with signature "susu" on interface "org.xfce.Session.Manager" doesn't exist ... nothing else while the video is playing. After quitting totem I see this: (totem:27938): GLib-GObject-WARNING **: 15:10:38.356: invalid (NULL) pointer instance (totem:27938): GLib-GObject-CRITICAL **: 15:10:38.356: g_signal_handlers_disconnect_matched: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed (totem:27938): GLib-GObject-WARNING **: 15:10:38.356: invalid (NULL) pointer instance (totem:27938): GLib-GObject-CRITICAL **: 15:10:38.356: g_signal_handlers_disconnect_matched: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed (totem:27938): GLib-GObject-WARNING **: 15:10:38.356: invalid (NULL) pointer instance (totem:27938): GLib-GObject-CRITICAL **: 15:10:38.356: g_signal_handlers_disconnect_matched: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed (totem:27938): Totem-CRITICAL **: 15:10:38.356: totem_object_empty_menu_section: assertion 'TOTEM_IS_OBJECT (totem)' failed > the builtin compositor can be disabled via xfwm4-tweaks-settings... launched xfwm4-tweaks-settings, to Compositor tab, unchecked the box [ ] Enable display compositing. Tried totem again, and no washed-out transparency. Workaround confirmed. Why this happens with totem and not mplayer, vlc, parole, mpv, or OpenShot, that's a head-scratcher. Especially mpv, since mpv & totem are linked to almost all the same libraries (mpv also uses libz.so.1 and linux-vdso.so.1) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767711 Title: Nvidia+XFCE: Totem window is see-through during playback, colours washed out To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1767711/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
