Green speckled dash...?

Ubuntu's dash turns green when I press the Super key after upgrading from Ubuntu 12.10 to Ubuntu 13.04. I'm not sure what causes the problem, and I haven't found any similar problems.

I have included a screenshot so you can see for yourself.

Any solutions?

  • Open up Terminal and use these commands dconf reset -f /org/compiz/ and unity --reset-icons. See if that works.

Okay, there was nothing wrong with my driver. I installed CompizConfig Settings Manager with

sudo apt-get install compizconfig-settings-manager

After I did that, I opened CompizConfig Settings Manager, and selected the Ubuntu Unity Plugin, and made sure that the background color was set to #000000 and that Dash Blur was set to No Blur.

This should fix the problem, as it did for me.

I found my answer from 13.04 Dash bug on Ubuntu Forums.


I had the same problem, hare is what I did:

  • Install Unity Tweak Tool from Ubuntu Software Centre.

  • In Unity Tweak Tool click on search button and deactivate background blur.

and that's it, everything is going to run OK.


I had similar problem with my nVidia graphic card on 12.10.

Go to System Settings > Software and Updates > Additional Drivers

and try to choose other option. It worked for me.
