I was wondering if someone can tell me where are the main Unity configuration files, at least the file that you can graphically configure through CCSM. I'm wanting to edit the dash size and the panel colour, but I didn't find where to do it.
Unity and Compiz are using GConf to store their settings. GConf is a configuration store that provides an API for applications to read and write configuration information and receive notifications when configuration items change. The configuration data is saved under ~/.gconf, but modifications should only be made through the GConf daemon.
You can modify the Unity settings directly using gconf-editor and browsing to /apps/compiz-1/plugins/unityshell/screen0/options. You will notice that Unity responds to changes instantly, the same as CCSM.
If you want a command line tool to modify these settings, use gconftool-2. For example, to reduce the launcher icon size I can do:
gconftool-2 --set /apps/compiz-1/plugins/unityshell/screen0/options/icon_size --type int 32
