I just upgraded my System to 14.04.
After restarting when the update was finished I did not see any menu bars or panels.
Right clicking and opening a terminal via ctrl+alt+t is not possible. However I can access the terminal via alt+F1. I already tried out installing the unity-desktop again but it didn't change anything .
Do you have any suggestions?

I tried reproducing your trouble by disabling Unity-plugin, after this resetting Unity or its settings didn't work. So, this what I've done trying to get it back:
install
Compiz Config Settings Manager
if you don't have it:Now, you have to go to
Compiz Config Settings Manager
and enableUnity-plugin
when Compiz manager opened navigate toUnity-plugin
or just type in searchUnity
then click on it and on the left put atick
wait a sec it should get back.How to get to
Compiz Manager
andTerminal
without Unity interface when nothing's responding even pressing Ctrl+Alt+T ? There's always the way to get around, for example press Ctrl+Alt+Del you'll getSystem Monitor
navigate toFile Systems
you'll get listed with your HDD subsections and simply click twice onHome section
now you should getNautilus
running. Navigate to/
and hit the search bar just typeTerminal
now you can launchTerminal
from search result, the same way typeCompizConfig
and you should get Compiz Manager launcher.What other ways you can try using
Terminal
try topurge
Unity
:Now reinstall it along with
ubuntu-desktop
simply type and run:This should automatically install and put Unity back on, you'll be able to see the packages that are going to be installed, if not run:
After all may require reboot, didn't occur to me.
if you want or need to reset Unity on Ubuntu 14.04 you can use
Unity Tweak Tool
to do so, if you don't have it installed:and to reset run:
Alternatives, all this stuff I wrote should definately work if everything else is fine including video drivers and you can try it in addition with
Gnome
for example, simply installgnome-shell
:now reboot, and then at the login screen choose
gnome-shell
and log in, if everything is ok, it should work 100%, if not, the problem is not only in Unity, it might refer to video drivers issues as well.These are all ways that I could figure out, so good luck!
