I just upgraded to Ubuntu 15.10 from 15.04.


  • The Unity sidebar and top bar are nowhere to be found. No matter if I push the cursor against the screen border.
    • The Unity top bar only appears when logging in. Fully interactive, functionality intact.
    • The Unity side bar is nowhere to be found. I never see it.
  • Another notable missing feature is ES-EN keyboard switching with Super+Space. I assume since it's part of the top bar.

Every other program seems to be working properly.

Also, I have the Variety wallpaper changer installed (still works), and think it could be a possible culprit.

I have tried:

  • Restarting.
  • Restarting Unity as shown in this answer.
  • Opening up the unity-tweak-tool and resetting all tabs to normal. I had a retractable/hidden side bar before the upgrade, but toggling this feature doesn't help.
  • Running sudo apt-get upgrade in case any packages were missing, to no avail.

I've managed to get by with Ctrl+Alt+T for opening up the terminal and Alt+Tab to change between opened program windows, but it's fairly uncomfortable.

Any ideas or assistance would be appreciated.

  • Did you try to restart unity with the terminal? Nov 3, 2015 at 2:41
  • Yes. Updated description to reflect that.

Hi I had the same problem you can install the compiz-config-manager from terminal and then just tick the unity box and enable unity from there

sudo apt-get install compizconfig-settings-manager
  • Installed as you said, but I'm unclear on how to start up the manager. Typing compizconfig-settings-manager brings up nothing...

  • Thanks! That solved it. Apparently there were conflicting key bindings and that disabled the Unity plugin. I'd upvote but my rep is too low ;p
