Today when I logged in to my Ubuntu 12.04, the update manager told me of some upgrades. Compiz and Unity were in those upgrades.

After I installed the upgrades, I can no longer get the Unity panel on the left side of screen or the systray at the top of screen. I now have to run Ubuntu 12.04 with Unity 2D. My laptop is a HP Pavilion dv9000 with Nvidia GeForce Go 7600 video.

I tried to run "unity --reset" but it says there are serious issues with compiz. I have cut & pasted the read out from the terminal below.

As you can see the terminal never comes back to the CI prompt. I must do a control C to get to the CI prompt, but then the OS is frozen. I have to reboot and run Unity 2D in able to do anything on my laptop. I hope I have explained this enough and provided some useful info. I am at a loss to understand what the problem is, or what exactly what is causing the problem. Is it Unity or Compiz? Can anyone help?
