After a restart my menu bar and launcher were missing. I have tried every solution for this issue that I can find, from re-installing unity and compiz to resetting Unity and everything.

Then I decided to reinstall Ubuntu 14.04 without formatting and still had the same problem.

When I run unity I get Error: Plugin 'opengl' not loaded.

What can I do?

first run

dpkg -l | grep opengl

This will tell you what opengl accelerators are installed on your system.

To search available packages, the following . . . 

apt-cache search openGL | grep plugin

. . . results in a few interesting results.

Notably,

compiz-plugins-default - OpenGL window and compositing manager - default plugins compiz-plugins - OpenGL window and compositing manager - plugins

Try running 

sudo apt-get install --reinstall compiz-plugins-default compiz-plugins compiz-plugins-extra compiz-plugins-main compiz-plugins-main-default compizconfig-settings-manager
