Ubuntu – How to get back unity and compiz after uninstalling, no launcher or dash on startup

14.04compizlauncherresetunity

I've gone through a ton of threads regarding this issue with nothing working for me. I removed compiz to reinstall it (foolishly) and I just can't seem to get unity back. I'm on 14.04.

The Unity Plugin is checked in Compiz Config Settings Manager.

enter image description here

I've tried uninstalling everything and reinstalling everything.

sudo apt-get remove compizconfig-settings-manager
sudo apt-get remove compiz-plugins-extra
sudo apt-get purge compiz*

sudo apt-get install ubuntu-desktop
sudo apt-get install compizconfig-settings-manager
sudo apt-get install git compiz-plugins-extra
sudo apt-get install compiz-plugins-extra
sudo apt-get install unity

One thing that I think my problem might be is that I can't get a connection with dconf.

When I try solutions like this:

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

or like this

sudo apt-get install unity-tweak-tool
unity-tweak-tool --reset-unity

I get a huge list of errors like

dconf-WARNING**: failed to commit changes to dconf: Could not connect: Connection refused
dconf-WARNING**: failed to commit changes to dconf: Could not connect: Connection refused

Anyone have other suggestions for how I can fix this? I'm desperate not to have to reinstall the operating system altogether.

Thanks in advance.

I had simmilar problems not long ago, this fixed the problem for me:

sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install --reinstall unity

This will force the reinstall without keeping the configuration files, that seem to be the cause of your problem.
