The Fedora (23) Mate comes with 4 desktops. How can I add more desktops? The manual says "right click on the desktop switcher applet -> settings. and change the amount of available deskops." There is no field to change the amount of desktops!
Just found it in another post. I am using compiz, so i have to change in the compiz settings:
this can easily be changed like described in the manual if you are using Marco (the default window-manager of MATE):
...or open a terminal and type
gsettings set org.mate.Marco.general num-workspaces 20 (20 is the number of workspaces/virtual desktops you wish; it must be between 1 and 36).
if you use Metacity i'm afraid there is no GUI-way to set the number of desktops, but it can be done by opening a terminal and enter
gsettings set org.gnome.desktop.wm.preferences num-workspaces 20 (20 is the number of workspaces/virtual desktops you wish; it must be between 1 and 36).
if you want to use Compiz have a look at this answer: https://askubuntu.com/a/34578/354350
change the window-manager:
to change the window-manager go to the Control Center and choose Desktop Settings, Windows and use the dropdown menu under Window Manager:
...or simply open a terminal and type
gsettings set com.linuxmint.desktop mate-window-manager marco.
