A week or so ago, I could use Autoscroll in Cinnamon on Fedora.

(I much prefer grab scroll, like in xreader, but I can't get it system-wide.)

I had reversed the scrolling direction under Cinnamon > Mouse and Trackpad > Reverse scrolling direction. But now everything ignores the scrolling direction, making Autoscroll harder for me to use. I've tested in Firefox, Xreader with the autoscroll option in the contextual menu, and LibreOffice, and in Cinnamon, and Gnome Classic. I've switched the setting back and forth, using both Cinnamon > Mouse and Trackpad > Reverse scrolling direction, and Gnome Classic > Settings > Mouse and Trackpad > (iirc) Natural Scrolling (not Traditional). But none of these affect the scrolling direction any more!

(I have trouble using scrollbars, and had painful tendon injuries for years after using scrollwheels.)

What are some possible causes, how can I test them, and how can I fix them and/or file a bug report?

And is there a system wide way to get grab scroll?

P.S. Here's the xinput list-prop data:

I assume that you're using Cinnamon in an Xorg session (not Wayland)?

I note that you also have another discussion about this here:

I thought it was a Cinnamon bug. I was wrong, and I'm not sure where to begin to debug it, so I asked here instead.

inxi -SGa doesn't say anything about the mouse.

No, that output was requested to provide definitive desktop information about your system.

You've provided system output confirming Cinnamon desktop. The graphics output would have confirmed Xorg or Wayland environment.

BTW, please use the code button when posting commands and output. It is the '#' button in the advanced editor.

(near-duplicate post; deleted in favor of revised version below.)

I'v also tested Cinnamon + Wayland and Gnome Classic + Xorg, same bug.

For some reason, switching between Cinnamon and Gnome Classic also keeps reverting my accessibility settings in Gnome Classic, so I get motion sickness every time I log into it.

Not sure what to suggest next. Perhaps cast your support net wider by posting to the Fedora Forum as well? For Wayland environments libinput gets configured by the compositor so there should be a mouse configuration utility for each display manager environment. With Xorg environments, the same applies, although an Xorg config file should take effect on a system-wide basis.

FWIW, libinput-config might be worth a shot...
https://discussion.fedoraproject.org...-config/100061
It allows configuration in Wayland environments when for some reason the desktop environment doesn't provide the necessary.

Okay, libinput list-devices says "natural scrolling" is disabled:

Ok, and is it disabled or enabled according to the Cinnamon mouse settings utility?
