The menu bar and Unity launcher have disappeared in Ubuntu 14.04. Also cannot access the terminal via ctrl + alt + t. I have tried every solution for this issue that I can find, from re-installing untiy and compiz to resetting Unity and everything. I've gone into the compiz manager and reactived Unity. Nothing has worked. When trying to reset Unity, or do anything with it really, I get this message (process:6332): dconf-WARNING **: failed to commit changes to dconf: Could not connect: Connection refused EDIT: Installed 14.04 a day ago. The issue happened after a reboot. After installing virtual Box
