The extension suddenly stopped working on Ubuntu 20.04

[Michael-E-Rose]

The extension suddenly stopped working this morning; all I have is a column of 4 workspaces. I cannot activate the extension via Extension (on the desktop), I can activate the extension both in Chrome and Firefox, but without effect and on the next restart it's all gone again.

I asked the question on SO: https://askubuntu.com/q/1397303/334172 Not sure it's my settings (which I didn't change since yesterday), the package (looks unlikely) or Gnome.

I am not sure if this is an issue with this extension wsmatrix or with the chrome-extension that allows you to install gnome extensions from the web.

GNOME 40 has an application named Extensions, this application shows you all the installed extensions and allows to configure them. Can you check if this Extensions applications shows the Workspace Matrix in the list or not?

If it's not there, then maybe you want to just install it manually with the method mentioned here https://github.com/mzur/gnome-shell-wsmatrix#manual-linux-method

I use Ubuntu 20.04, too, and the extension works without issues. Please also look for error messages in the log output when you execute journalctl /usr/bin/gnome-shell.

I only have one other extension, Desktop Icons, and that works fine. As soon as I install Workspache Matrix, the slider moves to off immediately.

Here is the first output related to the WS matrix:

I reinstalled GNOME Tweaks, and now finally I can slide Extensions on again. Weird stuff, and thanks for the help!

Your log output indicates that you use the Workspace Grid extension. This is not the same as Workspace Matrix.

[Michael-E-Rose]

So much I know, but a) Workspace Grid was never installed and b) isn't Workspace Matrix based on Worspace Grid?

[mzur]

a) Workspace Grid was never installed

It's definitely in your log output: workspace-grid@mathematical.coffee.gmail.com

b) isn't Workspace Matrix based on Worspace Grid

Only feature-wise. Workspace Matrix was written from scratch.
