Ubuntu 23.10 with GNOME 45 has replaced the top-left ‘Activities’ with a workspace indicator. By hovering over it, you can use mouse scroll to switch workspaces.

This is done by a simple extension called “Workspace Scroll”. Like the volume icon, with that extension, you can move mouse cursor over the top-left indicator, then scroll the middle mouse button to switch workspaces (aka Windows’ Virtual Desktop).

This can be useful for mouse heavily users, since it saves you a few mouse clicks!

How to Install Workspace Scroll

To install the extension for this feature, firstly press Ctrl+Alt+T on keyboard to open terminal.

Then, run command to install “Extension Manager” app:

sudo apt install gnome-shell-extension-manager

Next, click on top-left button to open overview, search for and launch “Extension Manager”.

Finally, use the tool to search and install the “Workspace Scroll” extension under ‘Browse’ tab.

For other Linux with GNOME 45, such as the upcoming Fedora 39, Arch/Manjaro etc, just open the link below:

Then use the ON/OFF switch to install that extension. If you don’t see the switch, install browser extension via the link in the page and refresh.

After installed the extension, just move your cursor to top-left indicator button, and scroll the middle wheel to verify.

In the recent update of Ubuntu 23.10 daily build, the GNOME desktop has been updated to v45 beta. And, here are some visual changes.

The default wallpaper now has a dark variant. Meaning changing Ubuntu Desktop to dark style will also change to dark style wallpaper. Though, the final wallpaper is not revealed yet!

The ‘Files’, aka Nautilus file manager, has been redesigned with more stylish layout. Which, supports drag and drop web image into file, and implements Global Search.

And, there’s new system extension to enhance tiling window support. Not only half screen tiling, it also support tiling window to quarter screen size, with either drag’n’drop or keyboard shortcuts, as well as features such as Tiling Pop-up and Tiling group.

By going to ‘Settings’ -> ‘Ubuntu Desktop’, you’ll see the new toggle options. Though, you can get even more by using “Extension Manager”.

Via the latest Gnome Shell package updates, the top-left ‘Activities’ button is finally replaced by an indicator. Now, it displays a white pill that indicates which workspace you’re on. Depends on how many workspaces you have, all others are indicated via gray dots.

As well, you may found the app menu, to indicate which app window is on focus, has also been removed. Though, the new Window Focus animation is not implemented at the moment.

They are even more great new features in Ubuntu 23.10. To try it out, just download the latest daily build image from the link below and install it in either real or virtual machine.

Ubuntu 23.10 is going to introduce new enhanced tiling window support! Here’s how you can try it out in Ubuntu 22.04 & Ubuntu 20.04.

For those who don’t know what is window tiling, it’s a window management behavior that snap window to screen edge/corner to be half or quarter-tile. So, you can work with 2, 3, or 4 app windows side by side in your screen.

Ubuntu so far has basic tiling support, that can only snap window to left or right half-tile. An enhanced tiling is available soon via a new built-in extension called “Tiling Assistant”.

By either dragging or use keyboard shortcut, user can tile window to left, right, top and bottom half, which is called Edge Tiling. And, tile window to top-left, top-right, bottom-left, and bottom-right quarter of screen, called Corner Tiling.

And, after tiling a window, it has a tiling pop-up feature that automatically show you ‘Super + Tab’ app switcher style pop-up to choose which app to auto-tile to the remaining screen space. And, when click focus (raise) a tiled window, all windows in the tile group raise together.

Run Ubuntu on laptop or other machine with touchscreen? You can enable touch feedback with an extension.

In these systems, it supports ripple feedback where the screen is touched. The feedback looks a bit like the locate mouse pointer function as the screenshot below shows you.

I don’t have a touchscreen device running Ubuntu. However, you can install and try the extension out by following steps one by one.
