How to change the number of workspaces from the command line?

Question

I'd like to change org.compiz.profiles.unity.plugins.core -> hsize and -> vsize from command line.

I thought I could use

gsettings set org.compiz.profiles.unity.plugins.core vsize 4

but then I've got an error message:

No such schema 'org.compiz.profiles.unity.plugins.core'

Is it possible at all? The setting can be clearly seen, as on the attached screenshot.

Solution 1

You can use dconf:

To get the current values:

dconf read /org/compiz/profiles/unity/plugins/core/hsize
dconf read /org/compiz/profiles/unity/plugins/core/vsize

To set new values:

dconf write /org/compiz/profiles/unity/plugins/core/hsize 2

Solution 2

The schema is org.compiz.core and it is a relocatable scheme (this makes it possible to support multiple profiles for Compiz).

For relocatable schemes you have to add the path if you use gsettings. It's /org/compiz/profiles/unity/plugins/core/ for the Compiz profile unity:

gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ hsize 4
gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ vsize 4

Reduce number of workspaces.

As I understand, gsettings is a preferred over dconf. It offers higher-level access to the dconf database. But I might be wrong.

This is only valid for application developers where the Gsettings API offers a cross platform access to the configuration database. Dconf access in your case (command line) is perfectly valid.

@frank you can use dconf write /org/compiz/profiles/unity/plugins/wall/allow-wraparound true to enable Wrap-Around and dconf write /org/compiz/profiles/unity/plugins/wall/allow-wraparound to disable it.

Any idea on how to enable or disable workspaces using dconf?
