I came across this in a Debian bug (https://bugs.debian.org/823195) and I found a workaround similar to comment #2. This works on Debian Sid, but not on Jessie, so this might not work on a system more than a year or two old.
Use normal (non-natural) scrolling in Xfce settings and run a command like: xinput --set-int-prop 12 "libinput Natural Scrolling Enabled" 8 1 You might have to replace the "12" with the ID of your mouse, which you can find with "xinput list". I think this is what GNOME's mouse settings does to enable natural scrolling. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1368402 Title: GTK3 apps don't understand natural scrolling in Xubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/xfce4-settings/+bug/1368402/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
