Problem: I have a stationary computer with ubuntu linux 18.04. 3 monitors connected and I can have maximum 9 workspaces. Even if I set "Gnome tweak tool" to 12 workspaces it shows only 9 workspaces. Note! The left/right monitor shows 12 workspaces.

Wanted behaviour: To set workspaces to more then 9 monitors, and that both center screen and side monitors show icon for the amount of screens.

Installations/Packages implemented:

(The packages are required but does not solve the problem with limit maximum 9 workspaces)

  • Gnome tweaks tool - To have extra workspaces.

  • Gnoe workspace grid -

  • Multi monitor add-on - to have workspaces visible on left/right screens.


  • I don't see. I was able to set 20 fixed workspaces that accordingly all show up as tiny thumbnails in the overview. This however may be related to the fact you have a multi-monitor setup, or to the multi-monitors extension.

  • @vanadium. I update the title to clarify that it is a 3-monitor-solution.

  • @pomsky I updated the question. The packages are a requirement to extend amount of monitors and have workspace visible on the 2nd/3rd monitor. But packages does not solve the problem of limitation 9 workspace.

By updating "multi monitors add-on" and "Gnome workspace grid" it is now possible in "workspace grid" to set up to 36 workspaces.
