Description Patrick Clancy 2021-03-23 23:57:53 UTC

After upgrading to "groovy" 20.10 from 20.04 via a do-release-upgrade, the mouse scroll wheel no longer switches between virtual desktops. The scroll wheel does work within a window. There were no reported problems during the upgrade.

Rightclicking the desktop -> Configure desktop -> Mouse actions:
The action "Vertical scroll" is present, set to "Switch desktop", but the first icon to the right of that (with the left/right arrow symbols) is greyed out.

How many virtual desktops do you have? Does it work if you move the wheel very slowly?

Comment 2 Patrick Clancy 2021-03-24 20:21:25 UTC

It's configured for 8 desktops, this is unchanged from before the system upgrade.

Moving the wheel very slowly doesn't make a difference.

One thing I noted, after going back to 20.04 for awhile: that greyed out icon I mentioned is also greyed-out in 20.04 with desktop scrolling working.

Thanks. Looks like this is a duplicate of Bug 419878.
