I've just upgraded from 14.04 LTS to 16.04 LTS. I am using Compiz as window manager. Unfortunately I am no longer able to use the mouse wheel on the workspace pane (bottom right on screen) to scroll forward/backward between the workspaces.

I have CompizConfig Settings Manager installed, but cannot find such a setting in it. Is there a way to enable this feature again?

  • Have you tried CTRL+ALT+ARROW KEY and CTRL+ALT+MOUSE WHEEL? – kevy Jul 18 '17 at 15:10
  • @VinuKevy: Ctrl+Alt+Arrow-Key is working. Ctrl+Alt+Mouse-Wheel is not doing anything. – Jenny O'Reilly Jul 18 '17 at 15:13
  • @JennyO'Reilly You should place your cursor over a window tray before using Ctrl+Alt+Mouse Wheel – Dami Sep 5 '18 at 9:55

To do so (presuming you have compizconfig-settings-manager installed)

Go to Desktop > Viewport Switcher.

enter image description here

It shows 20 buttons by default, which doesn't mean you actually can trigger 20 buttons.

To check which ones work, you can use the xev command. Type the command into a terminal, ensure the xev window has focus and then try your buttons.

  • Well it does seem to work with "button 4" and "button 5", but only if no program has the focus. For example if I have a firefox window open, it scrolls the page up/down instead of switching the workspace. I also tried it with some combinations (ctrl, shift, alt or super). But it is the same. Any ideas? – Jenny O'Reilly Jul 18 '17 at 16:30

It turns out that I was using the wrong window manager after the update to Ubutnu 16.04 LTS. In Ubuntu 14.04 LTS I was using Metacity which has this feature of switching workspaces with the mouse wheel by default. So I simply switched from Compiz back to Metacity.
