There is no launcher, menu bar and dash on my ubuntu 16.04. Happened when I logged in. Didn't do any changes to the system on my previous session. 16.04 has been working fine for me since it was released.
I know this has been answered before and I tried these answers:
Launcher, menubar and window borders disappeared in Ubuntu 16.04
I first did a reset of .config/dconf but that didn't do it.
Reinstalled Unity - no success
Disabled/Enabled Unity-plugin in Compiz-config-settings manager - no success
The icon for the Unity plugin in Compiz-config-settings manager looks like a question mark. Doesn't seem to look like that when I google images of the settings manager. Guess something is wrong with the plugin.
