Ubuntu – Ubuntu 16.04 upgrade issue

I have Ubuntu 16.04. The last upgrade did something to unity. No launcher, no top menus/toolbars in apps. Alt-Tab doesn't work. Cannot resize/move any app window. Running initctl restart unity-panel-service causes top bar to appear then disappear. Running unity-panel-service stop/waiting causes top bar, launcher and other things to appear then disappear. I have read through many of the questions and tried many of the solutions, but none have worked with my issue. If I can't get it fixed I'll have to switch to something else, as right now it is basically useless to me.

Round 2

Herman, I tried your suggestions, with the same results, except when I ran unity-panel-service stop/waiting, it said command not found. Based on another question I tried these:
sudo service lightdm restart bounced me to login. no launch, etc.
unity briefly caused menu bars to appear then disappear. I did a grep of the unity process number and got this:

obiii@Linux:~$ unity
unity-panel-service stop/waiting
unity7 stop/waiting
unity-panel-service start/running, process 6912
unity7 start/running, process 6921
obiii@Linux:~$ ps ux |grep 6921
obiii     6921  0.1  0.1 205512 11156 ?        Ssl  18:27   0:00 compiz
obiii     7046  0.0  0.0  14224  1016 pts/0    S+   18:27   0:00 grep --color=auto 6921

It appears that the unity service is running, but that something is hiding it. Also, I have an on-board graphics adapter in a Dell PowerEdge. I came up with this info:

obiii@Linux:~$ lspci | grep VGA
