I have a problem, I always have the dash Maximazed in full view, and well not like Is there a way to get the original one ??
The dash is designed to open "maximised" for screens that are approximately the size of a standard netbook. This is called "Netbook" mode.
You can force dash to open "half-way" using "Desktop" mode through the following:
gsettings set com.canonical.Unity form-factor 'Desktop'
If you want to reverse this try
gsettings set com.canonical.Unity form-factor 'Automatic'
gsettings set com.canonical.Unity form-factor 'Netbook'
Alternatively, you can install the configuration editor
dconf-editor from the package
dconf-tools and do the same the graphical way:
For 12.04 and later you can use MyUnity :
There is also a rather neat overlooked method...
Click the dash maximise button as shown, followed by the dash button itself. This changes from netbook to desktop and most importantly the setting is retained when you logout and login.
