A possible workaround is explained here: https://forums.linuxmint.com/viewtopic.php?t=242806
Adding this: GDK_CORE_DEVICE_EVENTS=1 at the end of ~/.profile solves this issue. GTK3 uses the X Input Device Extension Library by default. It seems that for some reason this extension is the source of the problem. Setting that environment variable, GKT3 only reacts to core X input events. It doesn't use that extension library. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mousetweaks in Ubuntu. https://bugs.launchpad.net/bugs/1354213 Title: With 'dwell-click' enabled there is no scrolling with mousewheel in gtk3 windows Status in mousetweaks package in Ubuntu: Confirmed Bug description: Test Case: enable dwell-click in System Settings > Universal access > Pointing & Clicking > Hover click or gsettings set org.gnome.desktop.a11y.mouse dwell-click-enabled true Try to scroll in a scroll-able gtk3 window with mouse wheel, nothing happens Scrolling is possible in gtk2 windows like Firefox ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: mousetweaks 3.12.0-1ubuntu1 ProcVersionSignature: Ubuntu 3.16.0-6.11-generic 3.16.0-rc7 Uname: Linux 3.16.0-6-generic x86_64 ApportVersion: 2.14.4-0ubuntu2 Architecture: amd64 CurrentDesktop: Unity Date: Thu Aug 7 19:33:45 2014 InstallationDate: Installed on 2014-07-31 (7 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Alpha amd64 (20140729) SourcePackage: mousetweaks UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mousetweaks/+bug/1354213/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
