Bug Description

I have Unity with System Settings -> Appearance -> Behavior -> Show the menus for a window: In the menu bar.

When I log in, often most of the apps don't present their menus in the topmost menu bar, rendering the entire desktop pretty much unusable.

In the top left corner I can see the app's name (e.g. "Text Editor" for gedit, "Terminal" for gnome-terminal, "System Settings", "Files" etc.). However, the apps' menu entries don't appear on mouseover, I still only see the app's name. Interestingly, Firefox is an exception, its menu is properly shown.

I have to log out and log in again to fix this situation.

The problem began to appear when I upgraded to Xenial alpha. I never saw this behavior in Wily and previous releases.

My crappy laptop reboots once or twice a day (when I happen to hold it in a certain angle). I have a feeling that this bug perhaps occurs right after reboots, although I'm not sure. It could be that upon crash some lock file remains there in my home and it triggers the buggy behavior. I should get my laptop fixed, I know, but an unclean exit of the desktop or a complete system crash must not be a reason for it not to start up properly the next time. I might be on the wrong track, I haven't tested logging out and back in when the desktop comes up properly. Maybe the bug has nothing to do with the spontaneous reboots.

I have the same problem on my pc, Latest daily fresh install (25/02/2016)

The only way to restart the menu is given from a terminal the following commands:

dconf reset -f /org/compiz/
unity --reset

Is your unity-gtk3-module installed, right?


env |grep GTK_MODULES|grep unity-gtk-module

Returns something?

I found that the menu returns to work even if I make the logout and then login

By enabling automatic login the problem no longer occurs and the menu always works every time the computer starts .
Turning off auto- login and the problem returns and the menu disappears

I don't have autologin either.

A "unity --reset" on its own solved the problem for me now.

Changed in unity (Ubuntu):
importance: Undecided → Critical

"unity --reset" or just "unity" solves the problem, but i must repeat the command after each login.
--reset (deprecated: provided for backwards compatibility)

Strangely, when I installed Unity8 (to try it out - which didn't work for me) the menus have reappeared on my Unity7 windows.
