Ubuntu MATE 18 workspace configuration file?

Physically the settings are saved in ~/.config/dconf/user, you need gsettings and/or dconf to read/write values to this file.

Below is the list of GUI options and their corresponding CLI equivalent:

1. Switcher

   • [ ] Show only the current workspace (default is false)

     dconf write /org/mate/panel/objects/workspace-switcher/prefs/display-all-workspaces 'false'
     

   • [o] Show all workspaces in N rows (default is 1 row):

     dconf write /org/mate/panel/objects/workspace-switcher/prefs/display-all-workspaces 'true'
     dconf write /org/mate/panel/objects/workspace-switcher/prefs/num-rows 1
     

2. Workspaces

   • Number of workspaces (default is 4)

     gsettings set org.mate.Marco.general num-workspaces 4
     

   • Workspace names

     gsettings set org.mate.Marco.workspace-names name-1 'Workspace 1'
     gsettings set org.mate.Marco.workspace-names name-2 'Workspace 2'
     gsettings set org.mate.Marco.workspace-names name-3 'Workspace 3'
     gsettings set org.mate.Marco.workspace-names name-4 'Workspace 4'
     

   • [ ] Show workspace names in switcher (default is false)

     dconf write /org/mate/panel/objects/workspace-switcher/prefs/display-workspace-names 'false'
     

   • [ ] Allow workspace wrap around in switcher (default is false)

     dconf write /org/mate/panel/objects/workspace-switcher/prefs/wrap-workspaces 'false'
