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?

I got this issue with ASUS notebook with ATI 58xx mobile after using Janitor (Ubuntu Tweak) or updates and could fix it (well at least get 2D) by 

sudo apt-get install fglrx-updates

Still try to get 3D back.

Okay first of all you either DONT'T ctrl-C when running that and you use "sudo service unity stop" and then "unity --reset"...

And then of coarse later go to unity 2d and go to your system settings> appearance>behavior>Reset to defaults, which should fix the problems, it always did for me...

OH OH OH and before you go to back to unity 3D, go to ccsm and go to "Ubuntu Unity plugin" and inside the settings there is a box to the left that lets you enable/disable the plugin...

MAKE SURE IT IS ENABLED!!!

^^Is wrong I' sorry...Here is the solution: Step 1: 

sudo apt-get install guake

Step 2: Go to startup applications and make sure guake is in it, if not add it.

Step 3: Launch unity 3d, and wait for guake to pop up, and then hit F12(or whatever key you set it to)

Step 4: In guake:

ccsm

Step 5: once compiz config settings manager is up (there shouldn't be any window borders) go to "Ubuntu Unity plugin" and click on it and enable it in the checkbox to the left.

Step 6: Back in guake make a new tab with "Shift+Ctrl+T" and inside there input:

unity --replace

Step 7: Go to this page a respond to this answer telling me your results...

  • Ok, sorry about the ctrl-C. I guess I was just running home to DOS. I will use the other commands you enclosed. Thanks. I will try the mentioned unity2d system settings and let you know the results. Thanks again.

  • I tried all of the above mentioned fixes. But none seem to have any effect on my problem. In Unity 3D I still have no "system tray" and no "unity panel".

  • Are you sure it is not just "Taking to long to load"? Because that and the fact I didn't have Ubuntu Unity plugin enabled were the only times that the panel didn't show up...

  • I really don't think it is just loading to slow. Example: My wife fixed lunch for me. I rebooted into Ubuntu 12.05 w/Unity 3D. $0 minutes later after lunch it was still like it was when I went to lunch. I have rechecked everything you recommended and all is enabled correctly. But no Unity 3D.

    I put this in as a "bug", Ubuntu replied that they "confirmed" the issue I was having. This morning there was an update to Unity in my Update Manager. I applied it, rebooted using Unity 3D, and it now works like it is suppose to. So I am going to close this out. Thanks for you help, I appreciate it.
