Mouse scroll wheel works selectively in Ubuntu VM

jm flag

I'm getting an odd issue in my Ubuntu 22.10 virtual machine running in Proxmox.

My mouse is a Razer wired mouse that's showing up in Ubuntu as "VirtualPS/2 VMWare VMMouse"

In Settings > Mouse & Touchpad, the scroll wheel is recognized and works properly when I "test my settings." However, it doesn't work in any other application, including terminal, Firefox, etc.

Elsewhere, I found information that I should use xev in the terminal. In xev, every single button on my mouse (including clicking the scroll wheel) is recognized properly, but nothing is registered on scroll.

I'm a bit confused about where to go next... I can't figure out why xev doesn't see my scroll wheel but the Mouse & Touchpad control panel somehow recognizes it.

Any pointers on where to turn next to get my scroll wheel working would be much appreciated.

This turned out to be an issue with web browsers in particular, after I realized that mouse scroll worked in desktop windows but not in Brave or Firefox.

Reinstalling Firefox did the trick on that browser.

On Brave, I needed to go to brave://flags and change the "Preferred Ozone platform" setting from "Default" to "Auto." I realized as I was fumbling around that Ubuntu was using XWayland, which I believe Brave was not using by default, leading it to ignore scroll wheel input? Or something.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
