The problem is identical to this question but with the additional problem that after trying out every thing mentioned there, unity still doesn't work.

I have tried installing/reinstalling ccsm, unity, unity-desktop. Enabling Unity Plugin didn't do anything. Removing/Renaming ~/.config/compiz-1 doesn't work.

The unity support check /usr/lib/nux/unity_support_test -p tells me my computer is capable of running unity.

GL framebuffer object:    yes

Trying setsid unity or unity --reset-icons &disown gives following:

GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications.
unity-panel-service stop/waiting

and it sort of hangs there without giving any error or doing anything. I have to terminate the process with ctrl+C.

unity --debug gives this:

again after which, it hangs there without doing anything or giving any error.

Right now, I have installed the gnome-panel and working with that, but I don't know how to get unity back working. Any help would be really appreciated.

  • I'm facing the same problem. I have other accounts on the same computer where the unity is working correctly. Thus the cause of the problem is somewhere in a user settings/enviroment... – mattirn Feb 05 '17 at 15:27

The Unity can be fixed by creating a new user as described here: Unity doesn't load, no Launcher, no Dash appears, ccsm method failed (Before marking duplicate please read the description)

I have explored this a bit further and I think unity can be fixed without creating a new user by following the procedure:

  1. login to system using gnome-panel and move directories .config and .cache:

    cd ~
mv .config config_save
mv .cache cache_save

  2. logout and login back now using unity. Move the saved files back to the .config and .cache direcories without overriding any files.

  • This method worked for me (ubuntu 16.04 lts) but caused me to lose all my settings. :( Probably better to first move the .cache directory and only move .config if moving the first doesn't help. – Stand with Gaza Jun 03 '19 at 13:28

Just want to report that something in my ~/.cache directory was causing this. Removed it, rebooted, and unity is back.

I followed the suggestion above and ran cd ~, mv .config config_save, then mv .cache cache_save. On reboot, I had Unity back.

My PC is a Lenovo C-260 set up with Ubuntu 16.04.3 installed. This morning, I did a dist-upgrade which resulted in Ubuntu 16.04.4 and a loss of Unity (desktop was OK) with no launch icons and no controls across the top.

I tried suggestions from numerous other postings, but nothing worked until I tried the above. Following these steps, I ran ccsm to check if the settings manager was retaining the proper checked boxes, which it wasn't doing previously, and everything is in order.

I faced similar problem but mine fixed after I deleted and reinstall lightdm.

Use these command:

sudo apt-get update
sudo apt-get remove lightdm
sudo apt-get install lightdm
sudo apt-get upgrade

If the above solution did not work for you, try removing everything from config using the command below:

sudo rm -rf ~/.config

This will reset everything and your Ubuntu system will resemble to the looks of a fresh install. Installed applications will be untouched.

  • Tried that as well but it didn't work for me. – alpha_lyrae Sep 30 '16 at 15:07
  • Is everything disappeared after system upgrade? – Shateel Sep 30 '16 at 15:09
  • No. I had installed 16.04 LTS directly on a new PC in August. Everything was working well for 1 month, and suddenly yesterday when I logged out after day's work and logged in again to copy some files I had forgotten, I was greeted with this problem. No idea why it would suddenly do this. – alpha_lyrae Sep 30 '16 at 15:16
  • rm -rf ~/.config try this command and let me know if it works? – Shateel Sep 30 '16 at 15:18
  • Have tried that already as well as it was one of the solutions suggested to the identical problem. Unfortunately that didn't work either. – alpha_lyrae Sep 30 '16 at 15:20
