I see the same issue after upgrading (yes, just recently, I'm a slacker) to 13.10 from 13.04, on evince and nautilus. I too am running XFCE. (Specifically 4.10)
Hovering over those applications and using the scroll wheel still raises them, just as if I'd clicked on them, but does not scroll them. "click scrolling" (as described above by Willy) does cause the applications in question to scroll. The click functionality of my scrollwheel is normal unix middle button behaviour. I will try the PPA listed above and report back. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1171342 Title: mouse scroll wheel not working in gedit & System Monitor Status in GTK+ GUI Toolkit: Fix Released Status in X.Org X server: Confirmed Status in “gtk+3.0” package in Ubuntu: Fix Released Status in “xorg-server” package in Ubuntu: Triaged Bug description: Open System Monitor Using mouse wheel button - scroll up or down - list does not move.
