I have been experimenting with new themes provided by noobslab.com, and I am having issues applying all parts. It seems the only icons I can set are Ubuntu's default, anything else gives me blank pages, as shown below:
To give and example, I used apt-get to install the azure theme. Once installed, the theme is available through the Unity Tweak Tool. Once clicked, the theme applies to windowing and the launch bar. In all cases the icons have to be changed manually using the tweak tool, however, the problem described previously always happens (only default icons work). Has anyone experienced this? Is there another tool I can use to get the job done? Thanks to all that reply.
