The error is caused by the patch 100_load_desired_settings.patch by adding:
/* return NULL if the file doesn't exist */ if (!g_file_test (filename, G_FILE_TEST_EXISTS)) { result = NULL; return result; } to the function configurations_read_from_file() in libgnome-desktop /gnome-rr-config.c, because it leaves the error passed to the function uninitialized which later causes the error in gnome-settings-deamon's xrandr-plugin (gsd-xrandr-manager.c, function apply_configuration_from_filename()). Removing that part makes the errors go away but for sure that's not a proper fix. No patch attached since I don't know how useful patching a patch is... -- GLib-CRITICAL **: g_propagate_error: assertion `src != NULL' failed https://bugs.launchpad.net/bugs/384439 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
