How to set scroll button and middle click emulation on a trackball in 22.04?

eg flag

I had middle click emulation and scroll on my Logitech TrackMan Marble using xorg.conf settings on my 20.04, but when I upgraded to 22.04 it stopped working, I tried various changes in xorg.conf (some of them broke my X completely) and nothing worked, what do I do?

After searching, I found out that wayland is changing the way things work on 22.04, and I need to change it via gsettings, I explored the various settings and what worked for me was this:

gsettings set org.gnome.desktop.peripherals.trackball scroll-wheel-emulation-button 8 # uses the second button from the left)
gsettings set org.gnome.desktop.peripherals.trackball middle-click-emulation true

If you use a mouse, change the trackball to mouse in the path.

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.
