After a crash and restart, my Ubuntu 16.04 desktop environment doesn't work - no launcher, no dash, nothing except a wallpaper. I can drop in a terminal by Ctrl+Alt+T, and then I follow the steps marked as answer here, that is

  1. reinstall compizconfig-settings-manager
  2. enable unity in ccsm

These steps above completed without error, however, problem persists. I also tried the following 

export DISPLAY=:0   
sudo dconf reset -f /org/compiz/

However I got the following error from dconf:

GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._g_2dfile_2derror_2dquark.Code17: Cannot open dconf database: invalid gvdb header

The ubuntu runs in a virtualbox in a MacOS 10.10 host. This should not be the problem because the desktop works as expected if I login in as Guest. The problem must be that something of my account is corrupted. Any advice is appreciated.

Update

I finally fixed the problem after hours of trial-and-error. Here is the solution for me: 

sudo apt install --reinstall unity
rm -r .Xauthority .ICEauthority .config/.compiz-1 .config/dconf

  • There are more different suggestions in the answers further below on that linked question. Please try them first as well. – Byte Commander Feb 07 '17 at 21:36
  • Will you add the output of df -v to your question? I'm thinking that the crash came from running out of space, and the lack of the desktop integrity the results of a lack of space. – L. D. James Feb 07 '17 at 23:29
  • @James: Still have space left. See the output df -v above. – sgu Feb 08 '17 at 00:07
  • Try doing this:sudo apt install --reinstall ubuntu-unity-desktop – axolotl Feb 08 '17 at 05:49
  • @zakoda: apt not able to find the ubuntu-unity-desktop. Is the package for ubuntu 16.04? – sgu Feb 08 '17 at 15:30
  • My bad, it should be just unity. Try now, by replacing the package name by unity – axolotl Feb 08 '17 at 15:35
  • @zakoda, reinstalled unity but problem persists. – sgu Feb 08 '17 at 15:50
  • install the package unity-tweak-tool as I remember that it has options to explicitly hide launcher and side panel. Perhaps you installed some other application and accidentally hid it. You could try altering the settings through unity-tweak-tool to see if this is the effect of a superficial trigger or change of state due to some other application. Again, I'm guessing your problem, so it may or may not work. Worth a try as it won't cause any harm/changes to your system. Also sounds like it's a problem like this ^ as it is user specific. – axolotl Feb 08 '17 at 15:54
