Never had this problem on my fully patched Ubuntu 16.04 until just recently, when I noticed that the Firefox menus do not display after restoring from a suspend. gnome-terminal and gedit are OK. Iconizing Firefox, then restoring, restores the menus to working condition. Same sorts of errors in ~/.cache/upstart/unity-panel-service.log as seen earlier.
cat ~/.cache/upstart/unity-panel-service.log (unity-panel-service:2121): Indicator-Appmenu-WARNING **: Already have a menu for window ID 65011728 with path /com/canonical/menu/3E00010 from :1.81, unregistering that one (unity-panel-service:2121): Indicator-Appmenu-CRITICAL **: menus_destroyed: assertion 'IS_WINDOW_MENU(wm)' failed (unity-panel-service:2121): Indicator-Appmenu-CRITICAL **: menus_destroyed: assertion 'IS_WINDOW_MENU(wm)' failed (unity-panel-service:2121): LIBDBUSMENU-GLIB-WARNING **: Unable to get menu proxy: Operation was cancelled (unity-panel-service:2121): Indicator-Appmenu-CRITICAL **: window_menu_model_new: assertion 'BAMF_IS_APPLICATION(app)' failed (unity-panel-service:2121): Indicator-Appmenu-CRITICAL **: track_menus: assertion 'IS_WINDOW_MENU(menus)' failed The window 3E00010 is the Firefox window. No unity process has died or been restarted. The bamfdaemon has been running since boot. What recently changed was adding a script to kill compiz returning from a suspend, so the Nvidia driver 375.39 screen artifacts get removed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1532226 Title: No menu bar in gtk apps on fresh boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1532226/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
