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
