Unable to activate "Workspace span displays" option

[RedaBousbah]

Describe the bug
When trying to activate the option "Workspace span displays" of Gnome (via Tweaks or bash) it is immediately disabled.
This also happens for "Static Workspaces".

Expected behavior
I want to be able to change workspace on all monitors when navigate them. This is an important part of my workflow, and is the only deal-breaker for using this amazing tool.

Screenshots

To Reproduce

• Occurs on:
  • X.Org
  • Wayland
• GNOME Shell version: 3.36
• Distro: Ubuntu 20.04
• Steps to reproduce, if applicable:

1. Open Tweaks
2. Go to "Workspaces"
3. Go to "Display Handling"
4. Click "Workspaces span displays"
5. Close Tweaks
6. Repeat steps 1-3, and see that "Workspaces span displays" is now disabled.

We are currently only compatible with the one workspace per external monitor mode since it's was the most adapted to my vision of the ideal workflow and also because altering the behavior of GNOME Shell can be a bit complex and maintain multiple mode can be very time consuming.
Therefore step after step our code base is becoming more mature and I may be incline to work a second option if there enough demands.
But we also have other fundamental stone to build like window resizing.

I don't know how to express it, but I'd love to see this as well! Thanks!

This would be pretty nice!
Or the option to have independent workspace-stacks per monitor (though I'm not sure how that would work with keyboard shortcuts and such).

I think, especially in a working environment, using multiple monitors is a must.

I am a developer myself and I make extensive use of workspaces, GNOME's workflows is made such that you never have to minimize a window (out of the box the minimize button is absent), if you need more space on the screen, add a workspace.
I usually work with 5 workspaces (2 screens each), making a total of 10 available programs. Not having this options means the best you can do (with 5 workspaces) is 6 usable windows, having an entire screen wasted...

Due to the fact that this is aimed at GNOME it is strange that it works so suboptimally with its core philosophy.

@RedaBousbah I'll work on it

@RedaBousbah I'll work on it

Thank you very much!

Love the work so far! For me, this is a must-have.

I really need this too.

My setup is a laptop which I then connect to two large monitors. The laptop remains as the primary display and the workspaces can only be added there. The two monitors remain static and are hugely underused.

I just started using/ testing Material Shell, and this is one of the things I miss the most.

I think it would be nice to have the option to "freeze" a monitor to a workspace for some tasks, just like the window option "Always on visible workspace", but for most part I need the workspace to change on all monitors.

Apart from this, I'm very impressed with Material Shell. Keep up the good work.

Definietly - I honestly just wait for this one feature to start using material shell - really love to see implementation of this <3

Aw I would love to see this too. I can't use it as is on my work PC for now. @PapyElGringo you made such a good job with material-shell, I hope you find the time to implement this.

@PapyElGringo I'm endorsing this request too. I'm impressed by Material Shell, after a few hours of usage, and I plan to stick to it for the future, but I really, really wish to see this new feature implemented ASAP. Looking forward to it, keep up the good work!
