How to get "smooth scrolling" system-wide?

  • 772

I found an amazing extension for Google Chrome called SmoothScroll. It makes scrolling webpages extraordinarily visually appealing, just like in opera.

I was wondering if I could find something like this for Ubuntu that can be applied system wide so that I can experience this on any scrollbar I use.

gnome gtk google-chrome

    Although it's a bit old, i found out that gnome 3.4 supports smooth scroll

    You will also see improvements to the building blocks that our applications have been made with. This includes smooth scrolling, refreshed user interface components, a much refined visual theme and application menus.

    Does anybody knows how to enable it?

  2. Firefox does have a smooth scroll option too.

    But as far as I know this is implemented in those applications (and AFAIK only for the browser window, not for other widgets?), not in standard Gtk widgets (or Xorg, or whatever), so no system-wide setting exists (that I know of).

  3. No system-wide setting as applications need to handle XInput 2.1 events themselves or use a toolkit that does it automatically.

    Gnome/GTK3 applications handle smooth or pixel-perfect scrolling by default.

    Firefox requires setting an environment variable MOZ_USE_XINPUT2 (echo 'export MOZ_USE_XINPUT2=1' >> ~/.xsessionrc).

    Chromium introduced it recently in version 54 and you will need to install it from an a source that is more up-to-date than Ubuntu's repositories.

    KDE/QT apps apparently have support though I haven't tried.

    Electron-based apps (such as Atom) don't have any support for XInput 2.1 events yet.
