I have the same issue on an nvidia GeForce GTX 960M Hardware with the same error output:
(totem:21578): GLib-GObject-CRITICAL **: 21:52:48.831: g_param_values_cmp: assertion 'G_IS_VALUE (value1)' failed Gdk-Message: 22:01:34.548: Error flushing display: Protokollfehler After removing `~/.config/totem/` and `~/.cache/totem/` totem could be started but crashes if I try to start a video or sound file. Starting via sudo seams to fix this, videos could be played, but w/o sound. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to egl-wayland in Ubuntu. https://bugs.launchpad.net/bugs/1966787 Title: Totem crashes on launch | GStreamer-GL-CRITICAL **: Failed to flush Wayland connection | Gdk-Message: Error flushing display: Protocol error To manage notifications about this bug go to: https://bugs.launchpad.net/egl-wayland/+bug/1966787/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
