Change Dash Home Background

Is it possible to change the dash home background from semi-transparent to a solid. I have tried MyUnity, and Ubuntu Tweak with no success. Thanks.

Unfortunately, the only thing you can do with it is to change the colour and change the blur settings.

The Dash is affected by the opacity setting in "Background Color" option of unity.
If you're using 12.10 you can use black (#000000) if a color doesn't suit, don't know if 12.04 was ever fixed for black

Just raise the opacity till you're happy with result
(on 12.10 if using a very high opacity then you may as well also switch to the "no blur" option

Whether these are in your helper apps don't know, otherwise install compizconfig-settings-manager & you'll find in the unity plugin settings

Ah... Didn't know that. Always thought Background Colour opacity had no real effect since changing the opacity doesn't change the launcher and the panel.
